X-rays from the location of the Bactrian Transient ASASSN-15lh
R. Margutti, B. D. Metzger, R. Chornock +13
We present the detection of persistent soft X-ray radiation with L_x ~ 10^41-10^42 erg/s at the location of the extremely luminous, double-humped transient ASASSN-15lh as revealed…
The GALEX Time Domain Survey. II. Wavelength-Dependent Variability of Active Galactic Nuclei in the Pan-STARRS1 Medium Deep Survey
T. Hung, S. Gezari, D. O. Jones +12
We analyze the wavelength-dependent variability of a sample of spectroscopically confirmed active galactic nuclei (AGN) selected from near-UV () variable sources in the GALEX…
Superluminous supernova 2015bn in the nebular phase: evidence for the engine-powered explosion of a stripped massive star
M. Nicholl, E. Berger, R. Margutti +25
We present nebular-phase imaging and spectroscopy for the hydrogen-poor superluminous supernova SN 2015bn, at redshift z=0.1136, spanning +250-400 d after maximum light. The light…
Revisiting the Lick Observatory Supernova Search Volume-Limited Sample: Updated Classifications and Revised Stripped-Envelope Supernova Fractions
Isaac Shivvers, Maryam Modjaz, Weikang Zheng +11
We re-examine the classifications of supernovae (SNe) presented in the Lick Observatory Supernova Search (LOSS) volume-limited sample with a focus on the stripped-envelope SNe. The…
The Afterglow and Early-Type Host Galaxy of the Short GRB 150101B at z=0.1343
Wen-fai Fong, Raffaella Margutti, Ryan Chornock +14
We present the discovery of the X-ray and optical afterglows of the short-duration GRB 150101B, pinpointing the event to an early-type host galaxy at z=0.1343 +/- 0.0030. This make…
A DECam Search for an Optical Counterpart to the LIGO Gravitational Wave Event GW151226
P. S. Cowperthwaite, E. Berger, M. Soares-Santos +97
We report the results of a Dark Energy Camera (DECam) optical follow-up of the gravitational wave (GW) event GW151226, discovered by the Advanced LIGO detectors. Our observations c…
PS1-14bj: A Hydrogen-Poor Superluminous Supernova With a Long Rise and Slow Decay
R. Lunnan, R. Chornock, E. Berger +27
We present photometry and spectroscopy of PS1-14bj, a hydrogen-poor superluminous supernova (SLSN) at redshift discovered in the last months of the Pan-STARRS1 Medium De…
A Dark Energy Camera Search for Missing Supergiants in the LMC After the Advanced LIGO Gravitational Wave Event GW150914
J. Annis, M. Soares-Santos, E. Berger +104
The collapse of the core of a star is expected to produce gravitational radiation. While this process will usually produce a luminous supernova, the optical signatue could be sublu…
Ejection of the massive Hydrogen-rich envelope timed with the collapse of the stripped SN2014C
Raffaella Margutti, A. Kamble, D. Milisavljevic +19
We present multi-wavelength observations of SN2014C during the first 500 days. These observations represent the first solid detection of a young extragalactic stripped-envelope SN…
