Hydrogen-Poor Superluminous Supernovae and Long-Duration Gamma-Ray Bursts Have Similar Host Galaxies
R. Lunnan, R. Chornock, E. Berger +27
We present optical spectroscopy and optical/near-IR photometry of 31 host galaxies of hydrogen-poor superluminous supernovae (SLSNe), including 15 events from the Pan-STARRS1 Mediu…
Short GRB 130603B: Discovery of a jet break in the optical and radio afterglows, and a mysterious late-time X-ray excess
Wen-fai Fong, Edo Berger, Brian D. Metzger +13
We present radio, optical/NIR, and X-ray observations of the afterglow of the short-duration 130603B, and uncover a break in the radio and optical bands at 0.5 d after the burst, b…
A panchromatic view of the restless SN2009ip reveals the explosive ejection of a massive star envelope
R. Margutti, D. Milisavljevic, A. M. Soderberg +54
The 2012 explosion of SN2009ip raises questions about our understanding of the late stages of massive star evolution. Here we present a comprehensive study of SN2009ip during its r…
A Reverse Shock in GRB 130427A
T. Laskar, E. Berger, B. A. Zauderer +7
We present extensive radio and millimeter observations of the unusually bright GRB 130427A at z=0.340, spanning 0.67 to 12 days after the burst. Taken in conjunction with detailed…
SN 2012au: A Golden Link Between Superluminous Supernovae and Their Lower-Luminosity Counterparts
D. Milisavljevic, A. Soderberg, R. Margutti +25
We present optical and near-infrared observations of SN 2012au, a slow-evolving supernova (SN) with properties that suggest a link between subsets of energetic and H-poor SNe and s…
PS1-10bzj: A Fast, Hydrogen-Poor Superluminous Supernova in a Metal Poor Host Galaxy
R. Lunnan, R. Chornock, E. Berger +26
We present observations and analysis of PS1-10bzj, a superluminous supernova (SLSN) discovered in the Pan-STARRS Medium Deep Survey at a redshift z = 0.650. Spectroscopically, PS1-…
