Prompt Emission from Tidal Disruptions of White Dwarfs by Intermediate Mass Black Holes
Roman V. Shcherbakov, Asaf Pe'er, Christopher S. Reynolds +3
We present a qualitative picture of prompt emission from tidal disruptions of white dwarfs (WD) by intermediate mass black holes (IMBH). The smaller size of an IMBH compared to a s…
The Einstein Toolkit: A Community Computational Infrastructure for Relativistic Astrophysics
Frank Löffler, Joshua Faber, Eloisa Bentivegna +10
We describe the Einstein Toolkit, a community-driven, freely accessible computational infrastructure intended for use in numerical relativity, relativistic astrophysics, and other…
Robustness of Binary Black Hole Mergers in the Presence of Spurious Radiation
Tanja Bode, Deirdre Shoemaker, Frank Herrmann +1
We present an investigation into how sensitive the last orbits and merger of binary black hole systems are to the presence of spurious radiation in the initial data. Our numerical…
Mergers of Supermassive Black Holes in Astrophysical Environments
Tanja Bode, Tamara Bogdanovic, Roland Haas +3
Modeling the late inspiral and merger of supermassive black holes is central to understanding accretion processes and the conditions under which electromagnetic emission accompanie…
GRHydro: A new open source general-relativistic magnetohydrodynamics code for the Einstein Toolkit
Philipp Moesta, Bruno C. Mundim, Joshua A. Faber +7
We present the new general-relativistic magnetohydrodynamics (GRMHD) capabilities of the Einstein Toolkit, an open-source community-driven numerical relativity and computational re…
Super-Extremal Spinning Black Holes via Accretion
Tanja Bode, Pablo Laguna, Richard A. Matzner
A Kerr black hole with mass and angular momentum satisfies the extremality inequality . In the presence of matter and/or gravitational radiation, this bound ne…
