Ultraviolet and optical observations of tidal disruption events [PDF]

open access: yesEPJ 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.

Relativistic cross sections of tidal disruption events [PDF]

open access: yesEPJ Web of Conferences, 2012
In this contribution I introduce and discuss the so-called cross sections of tidal disruption and partial mass stripping of stars after a tidal encounter with a rotating supermassive black hole. The presented approach is fully relativistic.

Optical Appearance of Eccentric Tidal Disruption Events [PDF]

open access: yesThe Astrophysical Journal Letters, 2023
Stars approaching supermassive black holes can be tidally disrupted. Despite being expected to emit X-rays, tidal disruption events (TDEs) have been largely observed in optical bands, which is poorly understood.

Simulations of Tidal Disruption Events [PDF]

open access: yes, 2020
Numerical simulations have historically played a major role in understanding the hydrodynamics of the tidal disruption process. Given the complexity of the geometry of the system, the challenges posed by the problem have indeed stimulated much work on ...

Tidal Disruption Event Demographics with the Zwicky Transient Facility: Volumetric Rates, Luminosity Function, and Implications for the Local Black Hole Mass Function [PDF]

open access: yesAstrophysical Journal Letters, 2023
We conduct a systematic tidal disruption event (TDE) demographics analysis using the largest sample of optically selected TDEs. A flux-limited, spectroscopically complete sample of 33 TDEs is constructed using the Zwicky Transient Facility over 3 yr ...

Ubiquitous Late Radio Emission from Tidal Disruption Events [PDF]

open access: yesAstrophysical 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 ...

Tormund's return: Hints of quasi-periodic eruption features from a recent optical tidal disruption event [PDF]

open access: yesAstronomy & Astrophysics, 2023
Quasi-periodic eruptions (QPEs) are repeating thermal X-ray bursts associated with accreting massive black holes, the precise underlying physical mechanisms of which are still unclear.

A Unified Theory of Jetted Tidal Disruption Events: From Promptly Escaping Relativistic to Delayed Transrelativistic Jets [PDF]

open access: yesAstrophysical Journal Letters, 2023
Only a tiny fraction ∼1% of stellar tidal disruption events (TDEs) generate powerful relativistic jets evidenced by luminous hard X-ray and radio emissions.

The rebrightening of a ROSAT-selected tidal disruption event: repeated weak partial disruption flares from a quiescent galaxy? [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2023
The ROSAT-selected tidal disruption event (TDE) candidate RX J133157.6-324319.7 (J1331), was detected in 1993 as a bright (0.2–2 keV flux of (1.0 ± 0.1) × 10−12 erg s−1 cm−2), ultra-soft (kT = 0.11 ± 0.03 keV) X-ray flare from a quiescent galaxy (z = 0.
