Compact Accretion Disks in the Aftermath of Tidal Disruption Events: Parameter Inference from Joint X-ray Spectra and UV/Optical Photometry Fitting
M. Guolo, A. Mummery, S. van Velzen +8
We present a multi-wavelength analysis of 14 tidal disruption events (TDEs)-including an off-nuclear event associated with an ultra-compact dwarf galaxy-selected for having availab…
JWST Discovery of a High-Redshift Tidal Disruption Event Candidate in COSMOS-Web
Mitchell Karmen, Suvi Gezari, Erini Lambrides +26
The rates and properties of tidal disruption events (TDEs) provide valuable insights into their host galaxy central stellar densities and the demographics of their central supermas…
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…
The Type I Superluminous Supernova Catalog I: Light Curve Properties, Models, and Catalog Description
Sebastian Gomez, Matt Nicholl, Edo Berger +25
We present the most comprehensive catalog to date of Type I Superluminous Supernovae (SLSNe), a class of stripped envelope supernovae (SNe) characterized by exceptionally high lumi…
Sub-relativistic Outflow and Hours-Timescale Large-amplitude X-ray Dips during Super-Eddington Accretion onto a Low-mass Massive Black Hole in the Tidal Disruption Event AT2022lri
Yuhan Yao, Muryel Guolo, Francesco Tombesi +32
We present the tidal disruption event (TDE) AT2022lri, hosted in a nearby ( Mpc) quiescent galaxy with a low-mass massive black hole ($10^4\,M_\odot < M_{\rm BH} < 10…
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.…
Episodic X-ray Outflows from the Tidal Disruption Event ASASSN-14li
Yukta Ajay, Dheeraj R. Pasham, Thomas Wevers +4
ASASSN-14li is a low-redshift () tidal disruption event (TDE) that has been studied extensively across the entire electromagnetic spectrum, and has provided one of the m…
A Multiwavelength study of the ongoing Changing-look AGN AT2021fxu
Yukta Ajay, Muryel Guolo, Dheeraj Pasham
We present multiwavelength analyses of an active optical transient AT2021fxu which shows the appearance of previously absent broad emission lines in a recent optical spectrum, sugg…
