Successive Partial Disruptions with Orbital Precession in a White Dwarf-Black Hole System for Repeating GRB 250702B
Yuri Sato, Rin Oikawa, Kazuma Kato +2
The peculiar gamma-ray burst GRB 250702B is the longest event ever observed, lasting about one day and exhibiting four prompt-emission flares of s with irregular recurren…
AT2019cmw: A highly luminous, cooling featureless TDE candidate from the disruption of a high mass star in an early-type galaxy
Jacob L. Wise, Daniel A. Perley, Nikhil Sarin +23
We present optical/UV photometric and spectroscopic observations, as well as X-ray and radio follow-up, of the extraordinary event AT2019cmw. With a peak bolometric luminosity of ~…
The Advanced X-ray Imaging Satellite (AXIS) Community Science Book
Michael Koss, Nafisa Aftab, Steven W. Allen +395
The AXIS Community Science Book represents the collective effort of 592 scientists worldwide to define the transformative science enabled by the Advanced X-ray Imaging Satellite (A…
VLBI Diagnostics of Off-axis Jets in Radio Flares of Tidal Disruption Events
Tatsuya Matsumoto
The origin of late-time radio flares in tidal disruption events remains unclear. In particular, the peculiar radio flare observed in AT2018hyz has motivated two leading scenarios:…
Quasi-Periodic Eruptions as a Probe of Accretion Disk in Tidal Disruption Events
Tomoya Suzuguchi, Tatsuya Matsumoto
Quasi-periodic eruptions (QPEs) are X-ray transients characterized by nearly regular recurring flares from galactic nuclei. Recent observations have confirmed that some QPEs occur…
Continued Rapid Radio Brightening of the Tidal Disruption Event AT2018hyz
Yvette Cendes, Edo Berger, Paz Beniamini +15
We present ongoing radio observations of the tidal disruption event (TDE) AT2018hyz, which was first detected in the radio at 972 days after disruption, following multiple non-dete…
