Tidal Disruption Encores [PDF]

The Astrophysical Journal Letters
Nuclear star clusters (NSCs), made up of a dense concentration of stars and the compact objects they leave behind, are ubiquitous in the central regions of galaxies surrounding the central supermassive black hole (SMBH).

Tidal Disruption of a Magnetized Star [PDF]

The Astrophysical Journal
Tidal disruptions of stars by supermassive black holes in galactic centers (TDEs) are now being actively studied both theoretically and observationally. They are observed throughout the electromagnetic spectrum, from radio to gamma-rays.

Shocks Power Tidal Disruption Events [PDF]

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.

A radio-emitting outflow produced by the tidal disruption event AT2020vwl [PDF]

Monthly Notices of the Royal Astronomical Society, 2023
A tidal disruption event (TDE) occurs when a star is destroyed by a supermassive black hole. Broadband radio spectral observations of TDEs trace the emission from any outflows or jets that are ejected from the vicinity of the supermassive black hole ...

Quasi-periodic X-ray eruptions years after a nearby tidal disruption event. [PDF]

Nature
Quasi-periodic eruptions (QPEs) are luminous bursts of soft X-rays from the nuclei of galaxies, repeating on timescales of hours to weeks1–5. The mechanism behind these rare systems is uncertain, but most theories involve accretion disks around ...

AT2019azh: an unusually long-lived, radio-bright thermal tidal disruption event [PDF]

Monthly Notices of the Royal Astronomical Society, 2022
Tidal disruption events (TDEs) occur when a star is destroyed by a supermassive black hole at the center of a galaxy, temporarily increasing the accretion rate onto the black hole and producing a bright flare across the electromagnetic spectrum.

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 [PDF]

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.

Fundamental scaling relationships revealed in the optical light curves of tidal disruption events [PDF]

Monthly Notices of the Royal Astronomical Society, 2023
We present fundamental scaling relationships between properties of the optical/UV light curves of tidal disruption events (TDEs) and the mass of the black hole that disrupted the star. We have uncovered these relations from the late-time emission of TDEs.

The γ-ray afterglows of tidal disruption events. [PDF]

Mon Not R Astron Soc, 2016
A star wandering too close to a supermassive black hole (SMBH) will be tidally disrupted. Previous studies of such "tidal disruption event" (TDE) mostly focus on the stellar debris that are bound to the system, because they give rise to luminous flares.
