Tanvir University of Leicester N ------------------------------------------------------------------------------------ Abstract During the past decade extraordinary progress has been made in determining the origin of long-duration gamma-ray bursts. It has been conclusively shown that these objects derive from the deaths of massive stars. Nonetheless, the origin of their observational cousins, short-duration gamma-ray bursts (SGRBs) remains a mystery. While SGRBs are widely thought to result from the inspiral of compact binaries, this is a conjecture. SGRBs have been found in elliptical galaxies, Abell Clusters, star-forming dwarfs and even an edge-on spiral. Whether they primarily result from an old population, a young population, or rapid evolution of binaries in globular clusters remains open. Here we propose to employ two related sets of observations which may dramatically advance our understanding of short bursts. The first is a variant of a technique that we pioneered and used to great effect in elucidating the origins of long-duration bursts. We will examine a statistical sample of hosts and measure the degree to which SGRB locations trace the red or blue light of their hosts, and thus old or young stellar populations. This will allow us to study the demographics of the SGRB population in a manner largely free of the distance dependent selection effects which have so far bedeviled this field. In the second line of attack we will use two targets of opportunity to obtain extremely precise positions of up to two nearby bursts -- one on a star-forming galaxy and the other on a elliptical. Observation of the star-formation galaxy could link at least some bursts directly to a young population; however, a discovery in later images of a globular cluster at the site of the explosion in an elliptical would provide revolutionary evidence that SGRBs are formed from compact binaries. ------------------------------------------------------------------------------------ Observations Description 11669( 7) - 17-Aug-2010 12:17:34 - [ 2] ------------------------ We propose to observe SGRB hosts where the location of the GRB is known to better than 0.2. In practice, these are GRBs with optical transients (OTs). The sample is derived from GRBs discovered since our last successful proposal, GO 11176, as well as two nearby GRBs which would be followed as ToOs. The positions of the last year?s GRBs have been obtained by early ground-based imaging, or in one case by a detection using the optical camera on Swift. Where we have VLT or Gemini detections of the optical transient, past experience shows we should be able to obtain relative astrometry between the ground and HST better than 0.05. The optical transient of GRB 070429B was only detected by the telescope on Swift. In this case, after taking an image with the CTIO 4-m to transfer the UVOT image to HST, we expect to have relative astrometry better than 0.2. The position of the optical transient of 070714B is from its discovery observations at the Liverpool Telescope. Here too our errors will be better than 0.2. Of course in the case of the ToOs (discussed in greater detail later) we should know the position of the GRB to better than an HST pixel. We will image all of last year?s hosts, and the star-forming ToO host, in ?blue? and ?red? filters. In cases where a redshift is known, we have chosen filters that will straddle the 4000 ? break. In other cases (primarily cases where the host magnitude is > 25), we have assumed that the redshift is comparable to or greater than one, and have chosen filters which should assure our two bands lie on opposite sides of the 4000 ? break. We will reach a SNR of 1.0 per pixel at 24 Vega mags per square arc-second in F160W in one orbit (about 25.6 mags AB) and 24.5 Vegamags in two orbits (we gain slightly over root two, as we use four dithers in both observations). Single orbits in F438W and F475W will reach a SNR of 1 per pixel at 24, and 24.7 B mag per square arc-second. The host of 071227, on which F438W must be used, is quite bright, so this depth should easily be sufficient. Similarly, two orbits of F606W on ACS will obtain a SNR of 1 on a (larger) ACS pixel at 25.2 R mag per square arc-second.
