PS1-10jh Continues to Follow the Fallback Accretion Rate of a Tidally Disrupted Star
S. Gezari, R. Chornock, A. Lawrence +5
We present late-time observations of the tidal disruption event candidate PS1-10jh. UV and optical imaging with HST/WFC3 localize the transient to be coincident with the host galax…
Discovery of an outflow from radio observations of the tidal disruption event ASASSN-14li
Kate D. Alexander, Edo Berger, James Guillochon +2
We report the discovery of transient radio emission from the nearby optically-discovered TDE ASASSN-14li (distance of 90 Mpc), making it the first typical TDE detected in the radio…
Unbound Debris Streams and Remnants Resulting From the Tidal Disruptions of Stars by Supermassive Black Holes
James Guillochon, Michael McCourt, Xian Chen +2
The kinetic energy of a star in orbit about a supermassive black hole is a significant fraction of its rest mass energy when its periapse is comparable to its tidal radius. Upon it…
The Offset and Host Light Distributions of Long Gamma-Ray Bursts: A New View from HST Observations of Swift Bursts
Peter K. Blanchard, Edo Berger, Wen-fai Fong
[Abridged] We present the results of an extensive Hubble Space Telescope (HST) imaging study of ~100 Swift long-duration gamma-ray bursts (LGRBs) spanning 0.03 < z < 9.4 using rela…
A Decade of Short-duration Gamma-ray Burst Broad-band Afterglows: Energetics, Circumburst Densities, and Jet Opening Angles
Wen-fai Fong, Edo Berger, Raffaella Margutti +1
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…
Swift J1112.2-8238: A Candidate Relativistic Tidal Disruption Flare
G. C. Brown, A. J. Levan, E. R. Stanway +5
We present observations of Swift J1112.2-8238, and identify it as a candidate relativistic tidal disruption flare (rTDF). The outburst was first detected by Swift/BAT in June 2011…
Energy Injection in Gamma-ray Burst Afterglows
Tanmoy Laskar, Edo Berger, Raffaella Margutti +4
We present multi-wavelength observations and modeling of Gamma-ray Bursts (GRBs) that exhibit a simultaneous re-brightening in their X-ray and optical light curves, and are also de…
GALEX Detection of Shock Breakout in Type II-P Supernova PS1-13arp: Implications for the Progenitor Star Wind
S. Gezari, D. O. Jones, N. E. Sanders +23
We present the GALEX detection of a UV burst at the time of explosion of an optically normal Type II-P supernova (PS1-13arp) from the Pan-STARRS1 survey at z=0.1665. The temperatur…
Extragalactic Transients in the Era of Wide-Field Radio Surveys. I. Detection Rates and Light Curve Characteristics
Brian D. Metzger, Peter K. G. Williams, Edo Berger
The impending era of wide-field radio surveys has the potential to revolutionize our understanding of astrophysical transients. Here we evaluate the prospects of a wide range of pl…
