Sifting for Sapphires: Systematic Selection of Tidal Disruption Events in iPTF
T. Hung, S. Gezari, S. B. Cenko +15
We present results from a systematic selection of tidal disruption events (TDEs) in a wide-area (4800~deg), band, Intermediate Palomar Transient Factory (iPTF) experiment…
Far-UV HST Spectroscopy of An Unusual Hydrogen Poor Superluminous Supernova: SN2017egm
Lin Yan, D. A. Perley, A. De Cia +4
SN2017egm is the closest (z=0.03) H-poor superluminous supernova (SLSN-I) detected to date, and a rare example of an SLSN-I in a massive and metal-rich galaxy. Here we present the…
Illuminating Gravitational Waves: A Concordant Picture of Photons from a Neutron Star Merger
M. M. Kasliwal, E. Nakar, L. P. Singer +78
Merging neutron stars offer an exquisite laboratory for simultaneously studying strong-field gravity and matter in extreme environments. We establish the physical association of an…
Light curves of hydrogen-poor Superluminous Supernovae from the Palomar Transient Factory
Annalisa De Cia, A. Gal-Yam, A. Rubin +24
We investigate the light-curve properties of a sample of 26 spectroscopically confirmed hydrogen-poor superluminous supernovae (SLSNe-I) in the Palomar Transient Factory (PTF) surv…
Spatially resolved analysis of Superluminous Supernovae PTF~11hrq and PTF~12dam host galaxies
Aleksandar Cikota, Annalisa De Cia, Steve Schulze +12
Superluminous supernovae (SLSNe) are the most luminous supernovae in the universe. They are found in extreme star-forming galaxies and are probably connected with the death of mass…
Hydrogen-poor Superluminous Supernovae With Late-time H-alpha Emission: Three Events From the Intermediate Palomar Transient Factory
Lin Yan, R. Lunnan, D. Perley +20
We present observations of two new hydrogen-poor superluminous supernovae (SLSN-I), iPTF15esb and iPTF16bad, showing late-time H-alpha emission with line luminosities of (1-3)e+41…
Discovery of a Mid-infrared Echo from the TDE candidate in the nucleus of ULIRG F01004-2237
Liming Dou, Tinggui Wang, Lin Yan +5
We present the mid-infrared (MIR) light curves (LCs) of a tidal disruption event (TDE) candidate in the center of a nearby ultraluminous infrared galaxy (ULIRG) F01004-2237 using a…
Revisiting optical tidal disruption events with iPTF16axa
T. Hung, S. Gezari, N. Blagorodnova +12
We report the discovery by the intermediate Palomar Transient Factory (iPTF) of a candidate tidal disruption event (TDE) iPTF16axa at , and present its broadband photometr…
