Circular_text TITLE: GCN CIRCULAR NUMBER: 14735 SUBJECT: GRB 130603B: Swift detection of a bright short burst DATE: 13/06/03 16:15:25 GMT FROM: David Palmer at LANL A. Melandri (INAF-OAB), W. H. Baumgartner (GSFC/UMBC), D. N. Burrows (PSU), J. R. Cummings (NASA/UMBC), N. Gehrels (NASA/GSFC), C. Gronwall (PSU), K. L. Page (U Leicester), D. M. Palmer (LANL), R. L. C. Starling (U Leicester) and T. N. Ukwatta (MSU) report on behalf of the Swift Team: At 15:49:14 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 130603B (trigger=557310). Swift slewed immediately to the burst. The BAT on-board calculated location is RA, Dec 172.209, +17.045 which is RA(J2000) = 11h 28m 50s Dec(J2000) = +17d 02' 42" with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve showed a single spike structure with a duration of about 0.4 sec. The peak count rate was 60000 counts/sec (15-350 keV), at ~0 sec after the trigger. The XRT began observing the field at 15:50:12.8 UT, 59.0 seconds after the BAT trigger. Using promptly downlinked data we find an uncatalogued X-ray source with an enhanced position: RA, Dec 172.2006, 17.0719 which is equivalent to: RA(J2000) = 11h 28m 48.16s Dec(J2000) = +17d 04' 18.8" with an uncertainty of 2.7 arcseconds (radius, 90% containment). This location is 101 arcseconds from the BAT onboard position, within the BAT error circle. This position may be improved as more data are received; the latest position is available at http://www.swift.ac.uk/sper. A power-law fit to a spectrum formed from promptly downlinked event data gives a column density in excess of the Galactic value (1.93 x 10^20 cm^-2, Kalberla et al. 2005), with an excess column of 6.8 (+4.00/-3.31) x 10^21 cm^-2 (90% confidence). UVOT took a finding chart exposure of 150 seconds with the White filter starting 62 seconds after the BAT trigger. No credible afterglow candidate has been found in the initial data products. The 2.7'x2.7' sub-image covers 25% of the BAT error circle. The typical 3-sigma upper limit has been about 19.6 mag. The 8'x8' region for the list of sources generated on-board covers 100% of the BAT error circle. The list of sources is typically complete to about 18 mag. No correction has been made for the expected extinction corresponding to E(B-V) of 0.02. The Swift star trackers were not locked at the time of the burst, so there may be some additional error in the position. However the spike in the rates and the image detection is unambiguously real. We note that this bright short hard GRB is near (12 arcminutes) the location of the nearby galaxy NGC 3691. At z=0.003566, this corresponds to a nominal projected distance of about 50 kpc. Burst Advocate for this burst is A. Melandri (andrea.melandri AT brera.inaf.it). Please contact the BA by email if you require additional information regarding Swift followup of this burst. In extremely urgent cases, after trying the Burst Advocate, you can contact the Swift PI by phone (see Swift TOO web site for information: http://www.swift.psu.edu/too.html.)

Osborne and A.P. Beardmore (U. Leicester) report on behalf of the Swift-XRT team. Using 712 s of XRT Photon Counting mode data and 1 UVOT images for GRB 130603B, we find an astrometrically corrected X-ray position (using the XRT-UVOT alignment and matching UVOT field sources to the USNO-B1 catalogue): RA, Dec = 172.20070, +17.07112 which is equivalent to: RA (J2000): 11h 28m 48.17s Dec (J2000): +17d 04' 16.0" with an uncertainty of 2.0 arcsec (radius, 90% confidence). This position may be improved as more data are received. The latest position can be viewed at http://www.swift.ac.uk/xrt_positions. Position enhancement is described by Goad et al. (2007, A&A, 476, 1401) and Evans et al. (2009, MNRAS, 397, 1177). This circular was automatically generated, and is an official product of the Swift-XRT team.

Baumgartner (GSFC/UMBC), J. R. Cummings (GSFC/UMBC), E. E. Fenimore (LANL), N. Gehrels (GSFC), H. A. Krimm (GSFC/USRA), A. Y. Lien (NASA/GSFC/ORAU), C. B. Markwardt (GSFC), A. Melandri (INAF-OAB), D. M. Palmer (LANL), T. Sakamoto (AGU), G. Sato (ISAS), M. Stamatikos (OSU), J. Tueller (GSFC), T. N. Ukwatta (MSU) (i.e. the Swift-BAT team): Using the data set from T-61 to T+242 sec from the recent telemetry downlink, we report further analysis of BAT GRB 130603B (trigger #557310) (Melandri, et al., GCN Circ. 14735). The BAT ground-calculated position is RA, Dec = 172.222, 17.063 deg, which is RA(J2000) = 11h 28m 53.2s Dec(J2000) = +17d 03' 48.2" with an uncertainty of 1.0 arcmin, (radius, sys+stat, 90% containment). The partial coding was 100%. The mask-weighted light curve shows a single FRED-like spike starting at ~T_0.000, peaking at ~T+0.012 sec, and returning to baseline at~T+0.2sec. There is a smaller pulse ridding on the tail of the initial pulse. T90 (15-350 keV) is 0.18 +- 0.02 sec (estimated error including systematics). The time-averaged spectrum from T+0.01 to T+0.26 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 0.82 +- 0.07. The fluence in the 15-150 keV band is 6.3 +- 0.3 x 10^-7 erg/cm2. The 1-sec peak photon flux measured from T-0.36 sec in the 15-150 keV band is 6.4 +- 0.3 ph/cm2/sec. All the quoted errors are at the 90% confidence level. The results of the batgrbproduct analysis are available at http://gcn.gsfc.nasa.gov/notices_s/557310/BA/

Tanvir, K. Wiersema (U. Leicester), O. Hartoog (Amsterdam), K. Kolle, J. Mendez (ING) and T. Kupfer (Nijmegan) report for a larger collaboration: We observed the location of GRB 130603B (Melandri et al. GCN 14735) with the William Herschel Telescope, beginning at 21:39 UT approximately 5.8 hours after the burst. In our z and r-band observations we identify a galaxy present in the SDSS DR9 observations of the field with a magnitude of r=20.94. In addition we identify a point-like source, offset approximately 1" to the SW of this source, with an approximate (+/- 1") position of; RA(J2000) 11 28 48.16 DEC(J2000) +17:04:18.0 This source is blended with the SDSS galaxy, but appears to be brighter. We suggest this is likely to be the optical afterglow of GRB 130603B."

Malesani (DARK/NBI), D. Xu (DARK/NBI), P. Jakobsson (U. Iceland), J. Datson (Tuorla Obs.), R. Salinas (FINCA), T. Augusteijn (NOT), Y. Martinez-Osorio (NOT), report on behalf of a larger collaboration: We observed the field of the short GRB 130603B (Melandri et al., GCN 14735) using the 2.5m NOT telescope beginning on 2013 Jun 3 at 21:22 UT. Observations consisted of 5x360 s in the r band. As noted by Levan et al. (GCN 14742), the refined XRT position (Evans et al., GCN 14739) straddles a galaxy detected in the SDSS, which has a photometric redshift z=0.39+/-0.11. Our images reveal a point source superimposed over this galaxy, and consistent with the XRT posion, at the following coordinates (J2000+/-0.5"): R.A.: 11:28:48.15 Dec.: +17:04:18.0 This source is not visible in the SDSS and it is the afterglow of GRB 130603B. We obtain a preliminary magnitude of r = 20.9 calibrated against SDSS (DR9). The afterglow is located ~0.8" SW of the host galaxy nucleus. Our results are consistent with those of Levan et al. (GCN 14742). [GCN OPS NOTE(06jun13): Per author's request, the author list was changed; 1 was dropped and 4 were added.]

Thne (IAA-CSIC), A. de Ugarte Postigo (IAA-CSIC/DARK), J. Gorosabel (IAA-CSIC/UPV-EUH), N. Tanvir (U. Leicester), and J. P. U. Fynbo (DARK/NBI) report: We obtained spectroscopy of the afterglow (GCN 14742, Levan et al, GCN 14743, de Ugarte Postigo et al.) of the short GRB 130603B (GCN 14735, Melandri et al.) with OSIRIS/GTC starting at 23:05 UT. Three spectra of 900s were obtained with grism R1000B. The afterglow lies on top of an SDSS galaxy as noted in Levan et al. The spectrum shows a strong trace of the afterglow with absorption lines of the Ca II doublet as well as MgII and MgI. Superimposed are emission lines from the host galaxy of [OII], [OIII], Hbeta and Hgamma extended in the spatial direction. Absorption and emission lines lie at a common redshift of z=0.356. We therefore determine this to be the redshift of the short GRB and its host galaxy. We acknowledge the excellent support by the GTC staff, in particular Rene Rutten and David Garcia.

Berger (Harvard), S. Jha (Rutgers) report: We observed the field of the short-duration GRB 130603B (Melandri et al., GCN 14735) with the Inamori Magellan Areal Camera and Spectrograph (IMACS) mounted on the Magellan/Baade 6.5-m telescope starting on 2013 Jun 04.004 UT (8.3-hr after the BAT trigger). In 600-s of r-band imaging, we detect the optical afterglow and host galaxy (Levan et al., GCN 14742; de Ugarte Postigo et al., GCN 14743). A 1200-s spectrum reveals several nebular emission lines from the host galaxy at a common redshift of 0.356, confirming the results of Thoene et al. (GCN 14744).

Gehrels (GSFC), S. D. Barthelmy (GSFC), T. Sakamoto (AGU) We report the spectral lag analysis for GRB 130603B (GCN Circ. 14735 & 14740) based on the BAT data. Using 2-ms binned light curves, the spectral lag for the 15-25 keV to 50-100 keV bands is 0.6 +-0.7 ms, and -2.5 +-0.7 mc for the 25-50 keV to 100-350 keV bands for both peaks combined. These lag values and the hard spectrum (GCN Circ. 14741) place this burst in the short burst category. There is no evidence for extended emission at the 0.005 cnts/det/sec level.

Snchez-Ramrez, A. J. Castro-Tirado (IAA-CSIC), J. Gorosabel (IAA-CSIC, UPV-EHU), F. J. Aceituno (IAA-CSIC), E. Sonbas (Adiyaman Univ.), E. Gogus, T. Gver (Sanbaci Univ.), H. Kirbiyik (TUG) and D. Garca-Alvrez (GTC) on behalf of a larger collaboration, report: We have observed the optical afterglow of the short-duration GRB 130603B (Melandri et al. GCNC 14735, Norris et al. GCNC 14746). Optical images have been obtained with the 1.0m telescope at the Tbitak National Observatory (Antalya, Turkey) in the R-band and with the 1.5m telescope at Observatorio de Sierra Nevada (Granada, Spain) in the I-band, starting on June 3. 771 and June 3.854 UT (2.69 hr and 4.69 hr post burst) respectively. Spectra covering the range 3500-10000 A were obtained with the 10.4m GTC (+OSIRIS) starting on June 3.993 UT (i.e. 8 hr post burst). At the position of the optical afterglow (Levan et al. GCNC 14742) the afterglow spectrum shows Ca II in absorption, and we detect significant contribution of the underlying host galaxy (eg. [OII], [OIII], H-beta and H-alpha emission lines about 1 off), implying altogether a redshift of z = 0.356, consistent with the values provided by Thoene et al. (GCNC 14744) and Foley et al.

Perley (Caltech), and S. B. Cenko (GSFC) report on behalf of a larger collaboration: On June 3.97 UT we start observing the optical afterglow of the Short GRB 130603B (Melandri et al. GCN 14735, Evans et al., GCN 14739, Levan et al. GCN 14742, and de Ugarte Postigo et al. GCN 14743) with the Gemini-South telescope equipped with the GMOS camera. The observation sequence consists of a series of 8x3min exposures in the g',r' and i' filters. The OT is clearly detected in individual exposures. Using the coadded frames and a 0.7" aperture, we estimate the following magnitudes: g = 21.7 +/- 0.2 r = 21.2 +/- 0.1 i = 20.7 +/- 0.2 These are not corrected for Galactic extinction or for contribution of the host galaxy, which is likely significant. An RGB image of the field showing the optical transient has been posted to: http://www.astro.caltech.edu/~dperley/gcn/130603b/130603b_gmos.png Also, a spectroscopic sequence was obtained: based on CaHK lines and several emission lines we confirm the redshift of GRB 130603B to be z=0.356 (as also reported by Thoene et al. GCN. 14744, Foley et al. 14745). We thank the Gemini South Staff, in particular A. Cardwell, J. Turner and Mischa Schirmer, for the excellent support.

Stroh (PSU), D.N. Burrows (PSU), A.P. Beardmore (U. Leicester), P.A. Evans (U. Leicester), B.P. Gompertz (U. Leicester), G. Stratta (ASDC), P. D'Avanzo (INAF-OAB), V. D'Elia (ASDC) and A. Melandri report on behalf of the Swift-XRT team: We have analysed 6.6 ks of XRT data for GRB 130603B (Melandri et al. GCN Circ. 14735), from 43 s to 28.2 ks after the BAT trigger. The data comprise 378 s in Windowed Timing (WT) mode (the first 9 s were taken while Swift was slewing) with the remainder in Photon Counting (PC) mode. The enhanced XRT position for this burst was given by Evans et al. (GCN. Circ 14739). The light curve can be modelled with an initial power-law decay with an index of alpha=0.35 (+0.08, -0.09), followed by a break at T+2404 s to an alpha of 1.46 (+0.13, -0.12). A spectrum formed from the WT mode data can be fitted with an absorbed power-law with a photon spectral index of 1.97 (+0.23, -0.22). The best-fitting absorption column is 2.8 (+1.0, -0.8) x 10^21 cm^-2, in excess of the Galactic value of 1.9 x 10^20 cm^-2 (Kalberla et al. 2005). The PC mode spectrum has a photon index of 2.21 (+0.18, -0.17) and a best-fitting absorption column of 2.5 (+/-0.5) x 10^21 cm^-2. The counts to observed (unabsorbed) 0.3-10 keV flux conversion factor deduced from this spectrum is 3.6 x 10^-11 (6.2 x 10^-11) erg cm^-2 count^-1. A summary of the PC-mode spectrum is thus: Total column: 2.5 (+/-0.5) x 10^21 cm^-2 Galactic foreground: 1.9 x 10^20 cm^-2 Excess significance: 7.7 sigma Photon index: 2.21 (+0.18, -0.17) If the light curve continues to decay with a power-law decay index of 1.46, the count rate at T+24 hours will be 4.7 x 10^-3 count s^-1, corresponding to an observed (unabsorbed) 0.3-10 keV flux of 1.7 x 10^-13 (2.9 x 10^-13) erg cm^-2 s^-1. The results of the XRT-team automatic analysis are available at http://www.swift.ac.uk/xrt_products/00557310. This circular is an official product of the Swift-XRT team.

In 1 hour of observations, we detect a ~0.2 mJy radio source in coincidence with the reported optical afterglow (Levan et al., GCN 14742; de Ugarte Postigo et al., GCN 14743; Foley et al., GCN 14745; Cucchiara et al., GCN 14748). We note that this is only the fourth detection of radio emission from a short GRB, of which one case (GRB 120804A; Berger et al., 2013, ApJ, 765, 121) was due to host galaxy emission. Further observations are planned. We thank the VLA staff for quickly executing these observations."

The observations started on 2013-06-04 at 00:00:28 UT (i.e., 8.187 hr after the burst). A total exposure of 4x600 s was obtained, covering the spectral range from ~300 to ~2100 nm. A continuum is detected in all the UVB/VIS/NIR arms of the spectra. We identify several absorption features which we interpret as Ca II H & K and Mg II from the optical afterglow, as well as emission lines such as the [O II] doublet, [O III], H-alpha, H-beta, and [S II] from the host galaxy, all at a common redshift of z=0.3564+/-0.0002, fully consistent with the measurements by Thoene et al.

Melandri (INAF-OAB) report on behalf of the Swift/UVOT team: The Swift/UVOT began settled observations of the field of GRB 130603B 62 s after the BAT trigger (Melandri et al., GCN Circ. 14735). A source 2'' from the centre of the XRT error circle (Evans et al. GCN Circ. 14739) and coincident with the optical afterglow detected by WHT (Levan et al., GCN circ. 14742) and NOT (de Ugarte Postigo et al., GCN circ. 14743) is detected in UVOT exposures. The source, in UVOT images, shows no clear fading behaviour between the first and the latest exposures. Preliminary detections and 3-sigma upper limits using the UVOT photometric system (Breeveld et al. 2011, AIP Conf. Proc. 1358, 373) for the early exposures are: Filter T_start(s) T_stop(s) Exp(s) Mag white 62 4981 383 20.81 0.17 v 605 5393 225 >19.8 b 530 6212 432 21.14 0.45 (2.5 sigma) u 275 6007 659 20.87 0.39 (2.8 sigma) w1 654 5802 413 >20.6 m2 3960 5597 393 >20.4 w2 580 6555 365 20.69 0.39 (2.8 sigma) The magnitudes in the table are not corrected for the Galactic extinction due to the reddening of E(B-V) = 0.02 in the direction of the burst (Schlegel et al. 1998).

Perley (Caltech) report on behalf of a larger collaboration: We have imaged the field of the short-hard GRB 130603B (Melandri et al., GCN 14735) with the robotic Palomar 60 inch telescope. Images were obtained in the r' and i' filters beginning at 04:00 on 2013 June 4 (~ 12.2 hr after the Swift trigger). At the location of the optical afterglow (Levan et al., GCN 14742), we detect a source mildly blended with the presumed host galaxy. Using a large aperture to include both objects, we measure a magnitude of r' = 20.8 at this time (calibrated with respect to several nearby point sources from SDSS).

Leicester), A. J. Levan (U. Warwick), A. S. Fruchter (STScI), J. Hjorth (DARK/NBI) and K. Wiersema (U. Leicester) report: We observed the location of GRB 130603B with HST/ACS and WFC3/IR. The host galaxy is clearly resolved as a disturbed spiral, and it appears that the GRB occurred close to a spiral arm that seems to have been tidally distorted or drawn out by interaction with a smaller neighbour. Our provisional analysis finds a point-source limit of F606W>27.6, corresponding to M_V~-14.3, at the location of the GRB. This is approaching a factor ~100 below what would be expected if there were a rising supernova comparable to SN1998bw, ruling out such an association for this burst. It also rules out some part of the parameter space of other radioactively-powered transients that have been proposed may accompany short GRBs. The position of the GRB lands on a region of extended emission in the F160W (H') filter of WFC3/IR. Another epoch scheduled for a few weeks from now will allow a deeper search for a counterpart through image subtraction. We thank the STScI director and staff for rapidly expediting these observations.

Berger and W. Fong (Harvard) report: "We obtained the public Hubble Space Telescope ACS/F606W and WFC3/F160W images of GRB 130603B (Tanvir et al. GCN #14893) from MAST and performed an astrometric tie of these images relative to our afterglow images from Magellan/IMACS (Foley et al. GCN #14745). The resulting total rms of the astrometic fit is 33 mas. At the location of the optical afterglow we identify an apparent point source in the WFC3/F160W image, with no corresponding counterpart in the ACS/F606W image (the circles marking the afterglow position have a radius of 10-sigma): https://www.cfa.harvard.edu/~eberger/GRB130603B_HST.tif PSF-matched photometry indicates m(F160W)=25.8+/-0.2 AB mag and m(F606W)>27.5 mag (3-sigma; the limit is consistent with Tanvir et al. GCN #14893). At the redshift of GRB 130603B (z=0.356) these values correspond to absolute magnitudes of M(F160W)=-15.2 mag and M(F606W)>-13.5 mag. The red V-H>1.7 mag color is potentially in good agreement with the afterglow g/r/i colors at early time (8.4 hr), which indicate a spectral index of beta~-1.7 (Cucchiara et al. arXiv:1306.2028). Based on this spectral index and the g/r/i magnitudes from Cucchiara et al., the interpolated/extrapolated magnitudes in the HST filters at 8.4 hr are m(F160W)=20.0 mag and m(F606W)=21.9 mag, or V-H~1.9 mag. Therefore, it is possible that the source detected in WFC3/F160W is the fading afterglow, indicating a decline rate of alpha_NIR~-1.6 between 8.4 hr and 9.4 days. Incidentally, this decline rate is in good agreement with the Swift/XRT decline rate of alpha_X~-1.6 at about 1 hr to 1 day ( http://www.swift.ac.uk/xrt_live_cat/00557310/) Alternatively, the red V-H color and the absolute magnitude of M(F160W)=-15.2 mag can be explained as emission from an r-process powered "kilonova", along the recent models by Barnes & Kasen arXiv:1303.5787. For their fiducial model (with M_ej=0.01 Msun and v_ej=0.1c), the expected absolute magnitude in the rest-frame J-band (corresponding to observed H-band) at an observed time of 9.4 days is about -15 mag, while the expected magnitude in the rest-frame B-band (corresponding to observed V-band) is exceedingly low (about -3 mag). Thus, it is possible that the red source we detected in the WFC3/F160W image represents the first detection of an r-process powered transient associated with a short GRB, thereby strengthening their association with NS-NS/NS-BH mergers. As noted by Tanvir et al. (GCN #14893) additional observations to determine variability are essential."

Ruffini, C.L. Bianco, M. Enderli, M. Muccino, A.V. Penacchioni, G.B. Pisani, J.A. Rueda, N. Sahakyan, Y. Wang report: After a rest-frame time of 5000 sec from the BAT trigger (Melandri et al., GCN 14735), the late X-ray rest-frame luminosity of GRB 130603B overlaps the one of GRB 090510A (see the figure at: ). This match occurs irrespectively of their isotropic energies, which differ by a factor of ~50 (GRB 130603B: E_iso = 2.1 * 10^51 erg, Frederiks et al., GCN 14772; GRB 090510A: E_iso = 1.1 * 10^53 erg, Muccino et al. 2013, ApJ, in press, arXiv:1306.3467). According to Muccino et al. 2013, GRB 090510A is a long GRB exploded in a high density enviroment (10^3 particles/cm^3). The similarity shown in the plot indicates that also GRB 130603B could be a long duration GRB observed at closer distance (z~0.35). Therefore the detection (or not detection) of a supernova associated to GRB 130603B between 20th-23rd of June, becomes a crucial test. Observations are strongly encouraged.

Taken together with the Swift/XRT afterglow light curve for t>4000 sec (Kennea et al., GCN 14749), these observations indicate a single power-law decline with index alpha_X=-1.83+/-0.15. Therefore, the XMM observations rule out the presence of a break at t~4000 sec to 2.57 d, in contrast to the suggested X-ray and optical break at ~8 hr (Tanvir et al., arXiv: 1306.4971)."

Digital image subtraction relative the first epoch (on 2013 June 13.15 UT) reveals that the near-IR point source coincident with the afterglow position has faded away, confirming our original suggestion that it is associated with GRB 130603B (Berger et al. 2013 arXiv:1306.3960). The subtraction also confirms our brightness measurement, with m(F160W)=25.8 AB mag. Coupled with an early steep decline in the optical band based on additional Magellan/IMACS observations at 32.2 hr post-burst, with r>24.8 AB mag (see also Cucchiara et al. 2013, arXiv:1306.2028; Tanvir et al. 2013, arXiv:1306.4971) this confirms the likely kilonova origin of this source."
