Rapid dimming followed by a state transition: a study of the highly variable nuclear transient AT 2019avd over 1000+ days
Yanan Wang, Dheeraj R. Pasham, Diego Altamirano +16
The tidal disruption of a star around a supermassive black hole (SMBH) offers a unique opportunity to study accretion onto a SMBH on a human-timescale. We present results from our…
A luminous dust-obscured Tidal Disruption Event candidate in a star forming galaxy at 42 Mpc
Christos Panagiotou, Kishalay De, Megan Masterson +11
While the vast majority of Tidal Disruption Events (TDEs) has been identified by wide-field sky surveys in the optical and X-ray bands, recent studies indicate that a considerable…
Unusual Hard X-ray Flares Caught in NICER Monitoring of the Binary Supermassive Black Hole Candidate AT2019cuk/Tick Tock/SDSS J1430+2303
Megan Masterson, Erin Kara, Dheeraj R. Pasham +17
The nuclear transient AT2019cuk/Tick Tock/SDSS J1430+2303 has been suggested to harbor a supermassive black hole (SMBH) binary near coalescence. We report results from high-cadence…
UV/Optical disk reverberation lags despite a faint X-ray corona in the AGN Mrk 335
Erin Kara, Aaron J. Barth, Edward M. Cackett +37
We present the first results from a 100-day Swift, NICER and ground-based X-ray/UV/optical reverberation mapping campaign of the Narrow-Line Seyfert 1 Mrk 335, when it was in an un…
Evidence for AGN-Regulated Cooling in Clusters at : A Multi-Wavelength View of SPT-CL J0607-4448
Megan Masterson, Michael McDonald, Behzad Ansarinejad +9
We present a multi-wavelength analysis of the galaxy cluster SPT-CL J0607-4448 (SPT0607), which is one of the most distant clusters discovered by the South Pole Telescope (SPT) at…
