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…
Repeating transients in galactic nuclei: confronting observations with theory
Petra Suková, Francesco Tombesi, Dheeraj R. Pasham +5
In the last few years, a mysterious new class of astrophysical objects has been uncovered. These are spatially coincident with the nuclei of external galaxies and show X-ray variat…
Alive and Strongly Kicking: Stable X-ray Quasi-Periodic Eruptions from eRO-QPE2 over 3.5 Years
Dheeraj Pasham, Shubham Kejriwal, Eric Coughlin +5
Quasi-periodic eruptions (QPEs) are recurring bursts of soft X-rays from the nuclei of galaxies. Their physical origin is currently a subject of debate, with models typically invok…
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…
Discovery of An Apparent Red, High-Velocity Type Ia Supernova at z = 2.9 with JWST
J. D. R. Pierel, M. Engesser, D. A. Coulter +27
We present the JWST discovery of SN 2023adsy, a transient object located in a host galaxy JADES-GS with a host spectroscopic redshift of . Th…
Extended emission line regions in post-starburst galaxies hosting tidal disruption events
Thomas Wevers, K. Decker French
We report the discovery of an extended emission line region (EELR) in MUSE observations of Markarian 950, a nearby () post-starburst (PSB) galaxy that hosted the tidal d…
