Formation of an accretion flow

C Bonnerot, NC Stone - Space Science Reviews, 2021 - Springer
After a star has been tidally disrupted by a black hole, the debris forms an elongated stream.
We start by studying the evolution of this gas before its bound part returns to the original …

Stellar tidal disruption events in general relativity

NC Stone, M Kesden, RM Cheng… - General Relativity and …, 2019 - Springer
A tidal disruption event (TDE) ensues when a star passes too close to a supermassive black
hole (SMBH) in a galactic center, and is ripped apart by its tidal field. The gaseous debris …

Populating the upper black hole mass gap through stellar collisions in young star clusters

K Kremer, M Spera, D Becker… - The Astrophysical …, 2020 - iopscience.iop.org
Theoretical modeling of massive stars predicts a gap in the black hole (BH) mass function
above∼ 40–50 M⊙ for BHs formed through single star evolution, arising from (pulsational) …

The missing link in gravitational-wave astronomy: discoveries waiting in the decihertz range

MA Sedda, CPL Berry, K Jani… - … and Quantum Gravity, 2020 - iopscience.iop.org
The gravitational-wave astronomical revolution began in 2015 with LIGO's observation of the
coalescence of two stellar-mass black holes. Over the coming decades, ground-based …

General relativistic hydrodynamic simulation of accretion flow from a stellar tidal disruption

H Shiokawa, JH Krolik, RM Cheng… - The Astrophysical …, 2015 - iopscience.iop.org
We study how the matter dispersed when a supermassive black hole tidally disrupts a star
joins an accretion flow. Combining a relativistic hydrodynamic simulation of the stellar …

A long-duration gamma-ray burst of dynamical origin from the nucleus of an ancient galaxy

AJ Levan, DB Malesani, BP Gompertz, AE Nugent… - Nature …, 2023 - nature.com
The majority of long-duration (> 2 s) gamma-ray bursts (GRBs) arise from the collapse of
massive stars, with a small proportion created from the merger of compact objects. Most of …

On the mass and luminosity functions of tidal disruption flares: rate suppression due to black hole event horizons

S van Velzen - The Astrophysical Journal, 2018 - iopscience.iop.org
The tidal disruption of a star by a massive black hole is expected to yield a luminous flare of
thermal emission. About two dozen of these stellar tidal disruption flares (TDFs) may have …

The Zwicky Transient Facility census of the local universe. I. Systematic search for calcium-rich gap transients reveals three related spectroscopic subclasses

Abstract Using the Zwicky Transient Facility alert stream, we are conducting a large
spectroscopic campaign to construct a complete, volume-limited sample of transients …

A dark year for tidal disruption events

J Guillochon, E Ramirez-Ruiz - The Astrophysical Journal, 2015 - iopscience.iop.org
Main-sequence disruptions of stars by supermassive black holes result in the production of
an extended, geometrically thin debris stream winding repeatedly around the black hole. In …

A Model for the Possible Connection Between a Tidal Disruption Event and Quasi-periodic Eruption in GSN 069

M Wang, J Yin, Y Ma, Q Wu - The Astrophysical Journal, 2022 - iopscience.iop.org
Quasi-periodic eruptions (QPEs) are found in the center of five galaxies, where a tidal
