AT2021lwx: Another Neutrino-coincident Tidal Disruption Event with a Strong Dust Echo? [PDF]
Astrophysical JournalWe discuss the possible association of an astrophysical neutrino (IC220405B) with the recently reported, extremely energetic tidal disruption event (TDE) candidate AT2021lwx (ZTF20abrbeie, aka “Scary Barbie”) at redshift z = 0.995.

Further evidence of Quasiperiodic Eruptions in a tidal disruption event AT2019vcb by SRG/eROSITA [PDF]
Monthly notices of the Royal Astronomical SocietyWe report the discovery of a short, large amplitude X-ray flare from AT2019vcb (aka Tormund), a tidal disruption event (TDE) at z = 0.088. The discovery is based on the data from the SRG/eROSITA X-ray telescope which happened to observe the source ...

Radio Observations of an Ordinary Outflow from the Tidal Disruption Event AT2019dsg [PDF]
Astrophysical Journal, 2021 We present detailed radio observations of the tidal disruption event (TDE) AT2019dsg, obtained with the Karl G. Jansky Very Large Array (VLA) and the Atacama Large Millimeter/submillimeter Array (ALMA), and spanning 55–560 days post disruption.

Tidal Stripping and Disruption of Globular Clusters [PDF]
Symposium - International Astronomical Union, 1985 Tidal stripping and disruption of globular clusters may be responsible for the absence of low density clusters in the inner region of the Galaxy. We have studied these processes by integrating orbits of stars while the cluster is moving through a spherically symmetric galactic potential with constant circular velocity (Vcir =220 km/s).

Signatures of Tidal Disruption of the Hercules Ultrafaint Dwarf Galaxy [PDF]
Astrophysical JournalThe Hercules ultrafaint dwarf galaxy (UFD) has long been hypothesized to be tidally disrupting, yet no conclusive evidence has been found for tidal disruption owing partly to difficulties in identifying Hercules member stars.

Infrared Echoes of Optical Tidal Disruption Events: ∼1% Dust-covering Factor or Less at Subparsec Scale [PDF]
Astrophysical Journal, 2021 The past decade has experienced an explosive increase of optically discovered tidal disruption events (TDEs) with the advent of modern time-domain surveys.

Underluminous tidal disruption events [PDF]
Monthly notices of the Royal Astronomical Society, 2023 We have evidence of X-ray flares in several galaxies consistent with a a star being tidally disrupted by a supermassive black hole (MBH). If the star starts on a nearly parabolic orbit relative to the MBH, one can derive that the fallback rate follows ...

Rapid Accretion State Transitions following the Tidal Disruption Event AT2018fyk [PDF]
Astrophysical Journal, 2021 Following a tidal disruption event (TDE), the accretion rate can evolve from quiescent to near-Eddington levels and back over timescales of months to years.
