An Extremely Luminous Panchromatic Outburst from the Nucleus of a Distant Galaxy
A recent bright emission observed by the Swift satellite is due to the sudden accretion of a star onto a massive black hole. Variable x-ray and γ-ray emission is characteristic of the most extremeExpand

Swift J2058.4+0516: Discovery of a possible second relativistic tidal disruption flare?
TLDR
Swift J2058+05 may be the second member of a new class of relativistic outbursts resulting from the tidal disruption of a star by a supermassive black hole. Expand

Swift and NuSTAR observations of GW170817: Detection of a blue kilonova
GROWTH observations of GW170817 The gravitational wave event GW170817 was caused by the merger of two neutron stars (see the Introduction by Smith). In three papers, teams associated with the GROWTHExpand

Afterglows, Redshifts, and Properties of Swift Gamma-Ray Bursts
We present optical, near-IR, and radio follow-up of 16 Swift bursts, including our discovery of nine afterglows and a redshift determination for three. These observations, supplemented by data fromExpand

A Population Of Massive, Luminous Galaxies Hosting Heavily Dust-Obscured Gamma-Ray Bursts: Implications For The Use Of Grbs As Tracers Of Cosmic Star Formation
We present observations and analysis of the host galaxies of 23 heavily dust-obscured gamma-ray bursts (GRBs) observed by the Swift satellite during the years 2005-2009, representing all GRBs with anExpand

The host galaxies of Type Ia supernovae discovered by the Palomar Transient Factory
We present spectroscopic observations of the host galaxies of 82 low-redshift Type Ia supernovae (SNe Ia) discovered by the Palomar Transient Factory. We determine star formation rates,Expand

SN 2010jl: OPTICAL TO HARD X-RAY OBSERVATIONS REVEAL AN EXPLOSION EMBEDDED IN A TEN SOLAR MASS COCOON
Some supernovae (SNe) may be powered by the interaction of the SN ejecta with a large amount of circumstellar matter (CSM). However, quantitative estimates of the CSM mass around such SNe are missingExpand

An achromatic break in the afterglow of the short GRB 140903A: evidence for a narrow jet
We report the results of our observing campaign on GRB140903A, a nearby (z=0.351) short duration (T90~0.3 s) gamma-ray burst discovered by Swift. We monitored the X-ray afterglow with Chandra up toExpand
