AGN on the move: A search for off-nuclear AGN from recoiling SMBHs and ongoing galaxy mergers with the Zwicky Transient Facility
Charlotte Ward, Suvi Gezari, Sara Frederick +16
A supermassive black hole (SMBH) ejected from the potential well of its host galaxy via gravitational wave recoil carries important information about the mass ratio and spin alignm…
TDE Hosts are Green and Centrally Concentrated: Signatures of a Post-Merger System
Erica Hammerstein, Suvi Gezari, Sjoert van Velzen +17
We study the properties of the galaxies hosting the first 19 tidal disruption events (TDEs) detected with the Zwicky Transient Facility (ZTF) within the context of a carefully cons…
A Family Tree of Optical Transients from Narrow-Line Seyfert 1 Galaxies
Sara Frederick, Suvi Gezari, Matthew J. Graham +17
The Zwicky Transient Facility (ZTF) has discovered five new events belonging to an emerging class of AGN undergoing smooth flares with large amplitudes and rapid rise times. This s…
A luminous X-ray transient in SDSS J143359.16+400636.0: a likely tidal disruption event
Murray Brightman, Charlotte Ward, Daniel Stern +9
We present the discovery of a luminous X-ray transient, serendipitously detected by Swift's X-ray Telescope (XRT) on 2020 February 5, located in the nucleus of the galaxy SDSS J143…
A tidal disruption event coincident with a high-energy neutrino
Robert Stein, Sjoert van Velzen, Marek Kowalski +55
Cosmic neutrinos provide a unique window into the otherwise-hidden mechanism of particle acceleration in astrophysical objects. A flux of high-energy neutrinos was discovered in 20…
A mildly relativistic outflow from the energetic, fast-rising blue optical transient CSS161010 in a dwarf galaxy
D. L. Coppejans, R. Margutti, G. Terreran +35
We present X-ray and radio observations of the Fast Blue Optical Transient (FBOT) CRTS-CSS161010 J045834-081803 (CSS161010 hereafter) at t=69-531 days. CSS161010 shows luminous X-r…
