Integral Field Spectroscopy of 13 Tidal Disruption Event Hosts from the ZTF Survey
Erica Hammerstein, S. Bradley Cenko, Suvi Gezari +6
The host galaxies of tidal disruption events (TDEs) have been shown to possess peculiar properties, including high central light concentrations, unusual star-formation histories, a…
Deja Vu All Over Again: The Reappearance of Supernova Refsdal
P. L. Kelly, S. A. Rodney, T. Treu +21
In Hubble Space Telescope (HST) imaging taken on 10 November 2014, four images of supernova (SN) "Refsdal" (redshift z=1.49) appeared in an Einstein-cross--like configuration (imag…
A Tidal Disruption Event in a Nearby Galaxy Hosting an Intermediate Mass Black Hole
Davide Donato, Stephen Bradley Cenko, Stefano Covino +9
We report the serendipitous discovery of a bright point source flare in the Abell cluster 1795 with archival EUVE and Chandra observations. Assuming the EUVE emission is associated…
The Progenitor of Supernova 2011dh/PTF11eon in Messier 51
Schuyler D. Van Dyk, Weidong Li, S. Bradley Cenko +12
We have identified a luminous star at the position of supernova (SN) 2011dh/PTF11eon, in pre-SN archival, multi-band images of the nearby, nearly face-on galaxy Messier 51 (M51) ob…
