[abridged] We investigate the afterglow properties and large-scale environments of several short-duration gamma-ray bursts (GRBs) with sub-arcsecond optical afterglow positions but no bright coincident host galaxies. The purpose of this joint study is to robustly assess the possibility of significant offsets, a hallmark of the compact object binary merger model. Five such events exist in the current sample of 20 short bursts with optical afterglows, and we find that their optical, X-ray, and… Expand
GEMINI SPECTROSCOPY OF THE SHORT-HARD GAMMA-RAY BURST GRB 130603B AFTERGLOW AND HOST GALAXY
We present early optical photometry and spectroscopy of the afterglow and host galaxy of the bright short-duration gamma-ray burst GRB 130603B discovered by the Swift satellite. Using our Target ofExpand
The Locations of Short Gamma-Ray Bursts as Evidence for Compact Object Binary Progenitors
We present a detailed investigation of Hubble Space Telescope rest-frame UV/optical observations of 22 short gamma-ray burst (GRB) host galaxies and sub-galactic environments. Utilizing the highExpand
A Decade of Short-duration Gamma-ray Burst Broadband Afterglows: Energetics, Circumburst Densities, and jet Opening Angles
We present a comprehensive catalog and analysis of broad-band afterglow observations for 103 short-duration gamma-ray bursts (GRBs), comprised of all short GRBs from November 2004 to March 2015 withExpand
Spectroscopy of the short-hard GRB 130603B: The host galaxy and environment of a compact object merger
Context. Short duration gamma-ray bursts (SGRBs) are thought to be related to the violent merger of compact objects, such as neutron stars or black holes, which makes them promising sources ofExpand
On the nature of the "hostless" short GRBs
A significant proportion (~30 per cent) of the short-duration gamma-ray bursts (SGRBs)localized by Swift have no detected host galaxy coincident with the burst location to deeplimits, and also noExpand
The Luminous Infrared Host Galaxy of Short-duration GRB 100206A
The known host galaxies of short-hard gamma-ray bursts (GRBs) to date are characterized by low to moderate star formation rates (SFRs) and a broad range of stellar masses, in general agreement withExpand
A Jet Break in the X-Ray Light Curve of Short Grb 111020a: Implications for Energetics and Rates
We present broadband observations of the afterglow and environment of the short GRB 111020A. An extensive X-ray light curve from Swift/XRT, XMM-Newton, and Chandra, spanning {approx}100 s to 10 daysExpand
Constraining the progenitors of short gamma-ray bursts
So far the progenitors of short γ-ray bursts (SGRBs) have proved elusive. Their presence within both old and young environments and their bias against starforming regions provide tantalisingExpand
Identifying the Location in the Host Galaxy of the Short GRB 111117A with the Chandra Subarcsecond Position
We present our successful Chandra program designed to identify, with subarcsecond accuracy, the X-ray afterglow of the short GRB 111117A, which was discovered by Swift and Fermi. Thanks to our rapidExpand
Implications of Understanding Short Gamma-Ray Bursts Detected by Swift
In an effort to understand the puzzle of classifying gamma-ray bursts (GRBs), we perform a systematic study of Swift GRBs and investigate several short GRB issues. Though short GRBs have a shortExpand
