Resolving the (Debate About) Nozzle Shocks in Tidal Disruption Events
Zachary L. Andalman, Eliot Quataert, Eric R. Coughlin +1
When a star passes within the Roche limit of a supermassive black hole (SMBH), it is pulled apart by the BH's tidal field in a tidal disruption event (TDE). The resulting flare is…
Estimation of Magnetic Fields from Synchrotron Emission: Numerical Tests
Nora B. Linzer, Lucia Armillotta, Eve C. Ostriker +1
We use models of spectrally resolved cosmic ray (CR) transport in TIGRESS MHD simulations of the local ISM to produce synthetic synchrotron emission and to test, on scales from a f…
X-ray Transmission Through Photoionized Gas with Moderate Thomson Optical Depth
Taya Govreen-Segal, Ehud Nakar, Eliot Quataert
We model the absorption of X-rays by gas obscuring the source and photoionized by it. We consider a broad range of column densities, including both Thomson-thin and Thomson-thick m…
Second public data release of the FIRE-2 cosmological zoom-in simulations of galaxy formation
Andrew Wetzel, Jenna Samuel, Pratik J. Gandhi +34
We describe the second data release (DR2) of the FIRE-2 cosmological zoom-in simulations of galaxy formation, from the Feedback In Realistic Environments (FIRE) project, available…
Super-Eddington accretion onto black holes and its application to fallback accretion
Tamar Faran, Eliot Quataert
We study the problem of steady-state spherical accretion onto a black hole, in which the internal energy of the flow is governed by radiation and photon diffusion dominates the ene…
Self-Similar Cosmic-Ray Transport in High-Resolution Magnetohydrodynamic Turbulence
Philipp Kempski, Drummond B. Fielding, Eliot Quataert +5
We study the propagation of cosmic rays (CRs) through a simulation of magnetohydrodynamic (MHD) turbulence at unprecedented resolution of . We drive turbulence that is…
