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 ...

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 ...

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.

First tidal disruption events discovered by SRG/eROSITA: X-ray/optical properties and X-ray luminosity function at z < 0.6 [PDF]
Monthly notices of the Royal Astronomical Society, 2021 We present the first sample of tidal disruption events (TDEs) discovered during the SRG all-sky survey. These 13 events were selected among X-ray transients detected in the 0 < l < 180○ hemisphere by eROSITA during its second sky survey (10 June–14 ...

Possible X-Ray Quasi-periodic Eruptions in a Tidal Disruption Event Candidate [PDF]
Astrophysical Journal Letters, 2021 X-ray quasi-periodic eruptions (QPEs) are a recently discovered phenomenon associated with supermassive black holes at the centers of galaxies. They are high-amplitude soft X-ray flares that recur on timescales of hours, but what causes these flares ...

Live to Die Another Day: The Rebrightening of AT 2018fyk as a Repeating Partial Tidal Disruption Event [PDF]
Astrophysical Journal Letters, 2022 Stars that interact with supermassive black holes (SMBHs) can be either completely or partially destroyed by tides. In a partial tidal disruption event (TDE), the high-density core of the star remains intact, and the low-density outer envelope of the ...

Magnetically Dominated Disks in Tidal Disruption Events and Quasi-Periodic Eruptions [PDF]
Monthly notices of the Royal Astronomical Society, 2022 The classical radiation pressure instability has been a persistent theoretical feature of thin, radiatively efficient accretion disks with accretion rates $\sim 1 - 100\%$ of the Eddington rate.

Nuclear Physics with Gravitational Waves from Neutron Stars Disrupted by Black Holes
The Astrophysical Journal Letters, 2023 Gravitational waves from neutron star–black hole (NSBH) mergers that undergo tidal disruption provide a potential avenue to study the equation of state of neutron stars and hence the behavior of matter at its most extreme densities.

Dynamical Unification of Tidal Disruption Events [PDF]
Astrophysical Journal Letters, 2022 The ∼100 tidal disruption events (TDEs) observed so far exhibit a wide range of emission properties both at peak and over their lifetimes. Some TDEs radiate predominantly at X-ray energies, while others radiate chiefly at UV and optical wavelengths ...

Cooling Envelope Model for Tidal Disruption Events [PDF]
Astrophysical Journal Letters, 2022 We present a toy model for the thermal optical/UV/X-ray emission from tidal disruption events (TDEs). Motivated by recent hydrodynamical simulations, we assume that the debris streams promptly and rapidly circularize (on the orbital period of the most ...
