We have added orientations to insure that diffraction spikes do not interfere with our observation. ----- Attempting Submission 2 (Mon Mar 19 23:42:41 GMT 2012) ----- HST Phase II Proposal 12502 (080905_update.apt) successfully submitted. ----- Attempting Submission 3 (Tue Mar 20 00:36:15 GMT 2012) ----- The number of orbits exceed the allotted orbits, as we are using part of our ToO orbits, but have not deleted ToO visits that are on hold (and which now would be modified before use). From the Locations to the Origins of Short Gamma-Ray Bursts While long-duration gamma-ray bursts (LGRBs) result from the collapse of massive stars, the progenitors of short-duration gamma-ray bursts (SGRBs) are still unknown. Although 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 spirals. Analysis of our Cycle 16 and Cycle 17 programs shows that the vast majority of SGRBs lie off of the rest-frame UV light (lambda < 400nm) of their hosts, and may even be more widely distributed than the red light (lambda > 600 nm). These results may be an indication that the progenitors of SGRBs have significant velocities. We will use two lines of attack to obtain substantial new insight into the origins of SGRBs. 1) WFC3 IR imaging of eleven hosts will nearly double the number of hosts with HST imaging in the rest-frame red. This new sample is large enough to turn the statistical suggestion already seen in the red light distribution into a statistical certainty, and would strongly imply that SGRBs are formed from compact binaries. Additionally if some of these bursts continue to show no evidence of an underlying host, models which predict neutron-star binaries with large velocities would be favored. 2) If an SGRB goes off in a nearby elliptical we will trigger a target of opportunity. The discovery of a globular cluster at the site of the explosion would provide revolutionary evidence that SGRBs are formed from compact binaries. We propose to observe all SGRBs localized to better than $0\farcs1$ since the Cycle 17 deadline. There are nine such bursts, all with optical or NIR transients observed with eight-meter telescopes. Based on past experience we can expect to be able transfer the astrometry to an HST image to better than $0\farcs05$, or less than the width of a drizzled WFC3/IR pixel. In addition we will observe the fields of two SGRBs that have already been imaged by ACS (GRB~060121) or WFPC2 (GRB~080503) without detecting the host. In the case of GRB~080503, the OT was still visible in one epoch, so for this burst we will be able to do astrometry to $\sim 0\farcs01$. All observations will be done in F160W of WFC3 to give us the reddest filter possible. We do this to attempt to avoid contaminating the red light profile of the galaxy by the narrower blue light profile, independent of redshift. Given the dramatic improvement in signal-to-noise ratio we have seen moving from WFPC2 or ACS to NICMOS, or for GRB~070714B, from the UVIS to the NIR on WFC3, observing in F160W would likely be a wise move even in the absence of this consideration. We will observe hosts with an R band magnitude brighter than 25 for one orbit, and fainter hosts for two orbits. We will reach a SNR of 1.0 per pixel at 24.1 Vega mags per arcsec$^2$ in F160W in one orbit (about 25.7 mags AB) and 24.5 Vegamags in two orbits. We find that a SNR of 1.0 per pixel works well with Sextractor in defining the boundary of the host. We make only one exception to our choice of F160W as our observing filter. This is in the search for an underlying globular cluster in the case of a burst going off in an elliptical with $z < 0.1$. Because of the exquisite PSF of the UVIS channel of WFC3, we will get a better optimal extraction SNR, and a better contrast between globular and elliptical, in the visible F606W filter than we would in the near-IR.
