Revealing the Nature of Extreme Coronal-line Emitter SDSS J095209.56+214313.3
Lovro Palaversa, Suvi Gezari, Branimir Sesar +4
Extreme coronal-line emitter (ECLE) SDSSJ095209.56+214313.3, known by its strong, fading, high ionization lines, has been a long standing candidate for a tidal disruption event, ho…
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…
Flows of X-ray gas reveal the disruption of a star by a massive black hole
Jon M. Miller, Jelle S. Kaastra, M. Coleman Miller +18
Tidal forces close to massive black holes can violently disrupt stars that make a close approach. These extreme events are discovered via bright X-ray and optical/UV flares in gala…
From Cosmic Birth to Living Earths: The Future of UVOIR Space Astronomy
Julianne Dalcanton, Sara Seager, Suzanne Aigrain +14
For the first time in history, humans have reached the point where it is possible to construct a revolutionary space-based observatory that has the capability to find dozens of Ear…
A Periodically Varying Luminous Quasar at z=2 from the Pan-STARRS1 Medium Deep Survey: A Candidate Supermassive Black Hole Binary in the Gravitational Wave-Driven Regime
Tingting Liu, Suvi Gezari, Sebastien Heinis +11
Supermassive black hole binaries (SMBHBs) should be an inevitable consequence of the hierarchical growth of massive galaxies through mergers, and the strongest sirens of gravitatio…
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…
