The Process of Stellar Tidal Disruption by Supermassive Black Holes [PDF]
, 2021 Tidal disruption events (TDEs) are among the brightest transients in the optical, ultraviolet, and X-ray sky. These flares are set into motion when a star is torn apart by the tidal field of a massive black hole, triggering a chain of events which is ...

The Final Season Reimagined: 30 Tidal Disruption Events from the ZTF-I Survey [PDF]
Astrophysical Journal, 2022 Tidal disruption events (TDEs) offer a unique way to study dormant black holes. While the number of observed TDEs has grown thanks to the emergence of wide-field surveys in the past few decades, questions regarding the nature of the observed optical, UV,

Tidal Disruption of Near-Earth Asteroids during Close Encounters with Terrestrial Planets [PDF]
Astrophysical Journal Letters, 2023 Numerical modeling has long suggested that gravitationally bound (or so-called rubble-pile) near-Earth asteroids (NEAs) can be destroyed by tidal forces during close and slow encounters with terrestrial planets.

Two Candidate Obscured Tidal Disruption Events Coincident with High-energy Neutrinos [PDF]
Astrophysical Journal Letters, 2023 Recently, three optical tidal disruption event (TDE) candidates discovered by the Zwicky Transient Facility (ZTF) have been suggested to be coincident with high-energy neutrinos.

Tidal Disruption Events and Dark Matter Scatterings with Neutrinos and Photons [PDF]
Physics Letters B, 2023 Stars can be tidally disrupted when passing near a black hole, and the debris can induce a flux of high-energy neutrinos. It has been discussed that there are hints in IceCube data of high-energy neutrinos produced in Tidal Disruption Events.

Partial stellar tidal disruption events and their rates [PDF]
Monthly notices of the Royal Astronomical Society, 2023 Tidal disruption events (TDEs) of stars operated by massive black holes (MBHs) will be detected in thousands by upcoming facilities such as the Vera Rubin Observatory. In this work, we assess the rates of standard total TDEs, destroying the entire star,

A Bright First Day for Tidal Disruption Events [PDF]
Astrophysical Journal, 2023 Stream–stream collision may be an important prepeak energy dissipation mechanism in tidal disruption events (TDEs). We perform local three-dimensional radiation hydrodynamic simulations in a wedge geometry including the gravity to study stream self ...

A Mildly Relativistic Outflow Launched Two Years after Disruption in Tidal Disruption Event AT2018hyz [PDF]
Astrophysical Journal, 2022 We present late-time radio/millimeter (as well as optical/UV and X-ray) detections of tidal disruption event (TDE) AT2018hyz, spanning 970–1300 d after optical discovery.

A bright year for tidal disruptions [PDF]
Monthly Notices of the Royal Astronomical Society, 2016 When a star is tidally disrupted by a supermassive black hole (BH), roughly half of its mass falls back to the BH at super-Eddington rates. Being tenuously gravitationally bound and unable to cool radiatively, only a small fraction f_in << 1 of the returning debris will likely be incorporated into the disk and accrete, with the vast majority ...

The maximum mass of a black hole which can tidally disrupt a star: Measuring black hole spins with tidal disruption events [PDF]
Monthly notices of the Royal Astronomical Society, 2023 The tidal acceleration experienced by an object at the event horizon of a black hole decreases as one over the square of the black hole’s mass. As such there is a maximum mass at which a black hole can tidally disrupt an object outside of its event ...
