Aarmed with Data: Bumps, Outflows, and Disk-like Emission in TDE 2025aarm
Aysha Aamer, Kate D. Alexander, Charlotte R. Angus +43
The origin of the optical emission in tidal disruption events (TDEs) remains one of the major outstanding questions in the field, in part due to the limited number of nearby events…
AT 2022csn: A Photometrically Peculiar Optical/UV Tidal Disruption Event in a Type II AGN
Yael Dgany, Iair Arcavi, Grisha Zeltyn +18
The emission mechanism and host galaxy preference of optical/UV tidal disruption events (TDEs) are still not entirely understood. We present observations of the TDE AT 2022csn, whi…
Infrared observations reveal the reprocessing envelope in the tidal disruption event AT 2019azh
Thomas M. Reynolds, Lars Thomsen, Seppo Mattila +14
Tidal disruption events (TDEs) are expected to release much of their energy in the far-ultraviolet (UV), which we do not observe directly. However, infrared (IR) observations can o…
The Double Tidal Disruption Event AT 2022dbl Implies That at Least Some "Standard" Optical TDEs are Partial Disruptions
Lydia Makrygianni, Iair Arcavi, Megan Newsome +37
Flares produced following the tidal disruption of stars by supermassive black holes can reveal the properties of the otherwise dormant majority of black holes and the physics of ac…
AT 2019aalc: a Bowen Fluorescence Flare With a Precursor Flare in an Active Galactic Nucleus
Marzena Śniegowska, Benny Trakhtenbrot, Lydia Makrygianni +10
AT 2019aalc is a peculiar sequence of highly variable emission events observed towards the nucleus of the broad-line AGN SDSS J152416.66+045119.0. The system exhibited two distinct…
Mapping the Inner 0.1 pc of a Supermassive Black Hole Environment with the Tidal Disruption Event and Extreme Coronal Line Emitter AT 2022upj
Megan Newsome, Iair Arcavi, D. Andrew Howell +10
Extreme coronal line emitters (ECLEs) are objects showing transient high-ionization lines in the centers of galaxies. They have been attributed to echoes of high-energy flares of i…
Light-Curve Structure and Halpha Line Formation in the Tidal Disruption Event AT 2019azh
Sara Faris, Iair Arcavi, Lydia Makrygianni +33
AT 2019azh is a H+He tidal disruption event (TDE) with one of the most extensive ultraviolet and optical data sets available to date. We present our photometric and spectroscopic o…
Probing the Sub-Parsec Dust of a Supermassive Black Hole with the Tidal Disruption Event AT 2020mot
Megan Newsome, Iair Arcavi, D. A. Howell +9
AT 2020mot is a typical UV/optical tidal disruption event (TDE) with no radio or X-ray signatures in a quiescent host. We find an i-band excess and re-brightening along the decline…
