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.

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

Searching for ultra-light bosons and constraining black hole spin distributions with stellar tidal disruption events. [PDF]
Nat Commun, 2022 Stars that pass close to the supermassive black holes located in the center of galaxies can be disrupted by tidal forces, leading to flares that are observed as bright transient events in sky surveys.

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.

Tidal Disruption Encores [PDF]
The Astrophysical Journal LettersNuclear 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).

Ubiquitous Late Radio Emission from Tidal Disruption Events [PDF]
The Astrophysical Journal, 2023 We present radio observations of 23 optically discovered tidal disruption events (TDEs) on timescales of ∼500–3200 days postdiscovery. We detect nine new TDEs that did not have detectable radio emission at earlier times, indicating a late-time ...

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 New Population of Mid-infrared-selected Tidal Disruption Events: Implications for Tidal Disruption Event Rates and Host Galaxy Properties [PDF]
The Astrophysical JournalMost tidal disruption events (TDEs) are currently found in time-domain optical and soft X-ray surveys, both of which are prone to significant obscuration. The infrared (IR), however, is a powerful probe of dust-enshrouded environments; hence, we recently

Astrophysical Journal LettersThe unluckiest star orbits a supermassive black hole elliptically. Every time it reaches the pericenter, it shallowly enters the tidal radius and gets partially tidally disrupted, producing a series of flares.

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 ...
