Multi-Frequency General Relativistic Radiation-Magnetohydrodynamic Simulations of Thin Disks
P. Chris Fragile, Peter Anninos, Nathaniel Roth +1
We present a set of six general relativistic, multi-frequency, radiation magnetohydrodynamic simulations of thin accretion disks with different target mass accretion rates around b…
StaNdaRT: A repository of standardized test models and outputs for supernova radiative transfer
Stéphane Blondin, Sergei Blinnikov, Fionntan P. Callan +26
We present the first results of a comprehensive supernova (SN) radiative-transfer (RT) code-comparison initiative (StaNdaRT), where the emission from the same set of standardized t…
An asymmetric electron-scattering photosphere around optical tidal disruption events
Giorgos Leloudas, Mattia Bulla, Aleksandar Cikota +10
A star crossing the tidal radius of a supermassive black hole will be spectacularly ripped apart with an accompanying burst of radiation. A few tens of such tidal disruption events…
Resolution Study of Thermonuclear Initiation in White Dwarf Tidal Disruption Events
Peter Anninos, Karen D. Camarda, Brooke Estes-Myers +1
We study the initiation of thermonuclear detonations in tidally disrupted white dwarf stars by intermediate-mass () black holes. The length scales required to resolve…
Dynamical Unification of Tidal Disruption Events
Lars Lund Thomsen, Tom Kwan, Lixin Dai +2
About a hundred tidal disruption events (TDEs) have been observed and they exhibit a wide range of emission properties both at peak and over their lifetimes. Some TDEs peak predomi…
General Relativistic Implicit Monte Carlo Radiation-Hydrodynamics
Nathaniel Roth, Peter Anninos, Peter B. Robinson +4
We report on a new capability added to our general relativistic radiation-magnetohydrodynamics code, Cosmos++: an implicit Monte Carlo (IMC) treatment for radiation transport. The…
