Delayed radio flares from a tidal disruption event [PDF]
Nature Astronomy, 2021 Radio observations of tidal disruption events (TDEs)—when a star is tidally disrupted by a supermassive black hole (SMBH)—provide a unique laboratory for studying outflows in the vicinity of SMBHs and their connection to accretion onto the supermassive ...

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 ...

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.

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 ...

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.

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.

AT 2022aedm and a New Class of Luminous, Fast-cooling Transients in Elliptical Galaxies
The Astrophysical Journal Letters, 2023 We present the discovery and extensive follow-up of a remarkable fast-evolving optical transient, AT 2022aedm, detected by the Asteroid Terrestrial impact Last Alert Survey (ATLAS).

Modelling the light-curves of objects tidally disrupted by a black hole
, 2009 Tidal disruption by massive black holes is a phenomenon, during which a large part of gravitational energy can be released on a very short time-scale. The time-scales and energies involved during X-ray and IR flares observed in Galactic centre suggest ...

Tidal Disruption of Milky Way Satellites with Shallow Dark Matter Density Profiles
Galaxies, 2016 Dwarf galaxies of the Local Group provide unique possibilities to test current theories of structure formation. Their number and properties have put the broadly accepted cold dark matter model into question, posing a few problems. These problems now seem

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.
