Shocks Power Tidal Disruption Events
The Astrophysical Journal, 2023 Accretion of debris seems to be the natural mechanism to power the radiation emitted during a tidal disruption event (TDE), in which a supermassive black hole tears apart a star.

Nuclear Physics with Gravitational Waves from Neutron Stars Disrupted by Black Holes
The Astrophysical Journal Letters, 2023 Gravitational waves from neutron star–black hole (NSBH) mergers that undergo tidal disruption provide a potential avenue to study the equation of state of neutron stars and hence the behavior of matter at its most extreme densities.

Extremely Relativistic Tidal Disruption Events
The Astrophysical Journal Letters, 2023 Extreme tidal disruption events (eTDEs), which occur when a star passes very close to a supermassive black hole, may provide a way to observe a long-sought general relativistic effect: orbits that wind several times around a black hole and then leave ...

Interpretation of the Observed Neutrino Emission from Three Tidal Disruption Events
The Astrophysical Journal, 2023 Three Tidal Disruption Event candidates (AT2019 dsg , AT2019 fdr , and AT2019 aalc ) have been associated with high-energy astrophysical neutrinos in multimessenger follow-ups.

Relativistic tidal disruption events
EPJ Web of Conferences, 2012 In March 2011 Swift detected an extremely luminous and long-lived outburst from the nucleus of an otherwise quiescent, low luminosity (LMC-like) galaxy. Named Swift J1644+57, its combination of high-energy luminosity (1048 ergs s−1 at peak), rapid X-ray ...

Tidal flares and rates from an archival cluster survey
EPJ Web of Conferences, 2012 Tidal disruption flares (TDFs) are potent indicators of the co-evolution of galaxies and the massive black holes (MBHs) which they host in their nuclei, both in terms of the individual black holes revealed by tidal flares and in terms of the overall ...

The Astrophysical Journal Letters, 2023 We report the discovery of a faint optical tidal disruption event (TDE) in the nearby star-forming galaxy NGC 3799. Identification of the TDE is based on its position at the galaxy nucleus, a light curve declining as t ^−5/3 , a blue continuum with an ...

Stellar dynamics and tidal disruption events in galactic nuclei
EPJ Web of Conferences, 2012 The disruption of a star by the tidal field of a massive black hole is the final outcome of a chain of complex dynamical processes in the host galaxy. I introduce the “loss cone problem”, and describe the many theoretical and numerical challenges on the ...

Rubin Observatory’s Survey Strategy Performance for Tidal Disruption Events
The Astrophysical Journal Supplement Series, 2023 Tidal disruption events (TDEs) are rare transients, which are considered as promising tools for probing supermassive black holes in quiescent galaxies.

Ultraviolet and optical observations of tidal disruption events
EPJ Web of Conferences, 2012 Tidal disruption events are expected to produce a luminous flare of radiation from fallback accretion of tidally disrupted stellar debris onto the central supermassive black hole.
