Repeated Partial Tidal Disruptions and Quasi-Periodic Eruptions in SwJ023017.0+283603
Dheeraj Pasham, Eric Coughlin, Chris Nixon +5
SwJ023017.0+283603 (SwJ0230) exhibited soft X-ray (0.3-1.0 keV) eruptions recurring roughly every 22 days. We present results from an extended monitoring campaign of SwJ0230 using…
A Potential Second Shutoff from AT2018fyk: An updated Orbital Ephemeris of the Surviving Star under the Repeating Partial Tidal Disruption Event Paradigm
Dheeraj Pasham, Eric Coughlin, Muryel Guolo +4
The tidal disruption event (TDE) AT2018dyk/ASASSN-18UL showed a rapid dimming event 500 days after discovery, followed by a re-brightening roughly 700 days later. It has been hypot…
Repeating nuclear transients from repeating partial tidal disruption events: reproducing ASASSN-14ko and AT2020vdq
Ananya Bandopadhyay, Eric R. Coughlin, C. J. Nixon +1
Some electromagnetic outbursts from the nuclei of distant galaxies have been found to repeat on months-to-years timescales, and each of these sources can putatively arise from the…
Ultra-deep cover: an exotic and jetted tidal disruption event candidate disguised as a gamma-ray burst
R. A. J. Eyles-Ferris, C. J. Nixon, E. R. Coughlin +1
Gamma-ray bursts (GRBs) are traditionally classified as either short GRBs with durations s that are powered by compact object mergers, or long GRBs with durations $\gt…
Alive but Barely Kicking: News from 3+ years of Swift and XMM-Newton X-ray Monitoring of Quasi-Periodic Eruptions from eRO-QPE1
Dheeraj R. Pasham, Eric R. Coughlin, Michal Zajacek +11
Quasi-periodic Eruptions (QPEs) represent a novel class of extragalactic X-ray transients that are known to repeat at roughly regular intervals of a few hours to days. Their underl…
Lense-Thirring Precession after a Supermassive Black Hole Disrupts a Star
Dheeraj R. Pasham, Michal Zajacek, C. J. Nixon +8
An accretion disk formed around a supermassive black hole (SMBH) after it disrupts a star is expected to be initially misaligned with respect to the black hole's equatorial plane.…
