Star-Disk Collisions II: Debris Stream Dynamics and Implications for QPEs and Other Transients Near SMBHs
Philippe Z. Yao, Eliot Quataert, Yan-Fei Jiang +1
Quasi-periodic eruptions (QPEs) are repeating soft X-ray nuclear transients with recurrence times of hours-days and flare duty cycles of 10-20%. Many aspects of QPEs can be m…
Radiation GRMHD Models of Accretion onto Stellar-Mass Black Holes: III. Near-Eddington Accretion
Lizhong Zhang, James M. Stone, Shane W. Davis +3
We present a comprehensive analysis of four near-Eddington black hole accretion models from GRMHD simulations with full radiation transport. This study investigates the dynamical e…
PACHA: Probing AGN Coronae with High-redshift AGN
Xiurui Zhao, Elias Kammoun, Marco Ajello +19
The X-ray emission of active galactic nuclei (AGN) is generally attributed to inverse Compton scattering of accretion-disk photons by hot electrons in a compact corona. In local AG…
Non-Stationary Discs and Instabilities
Omer Blaes, Yan-Fei Jiang, Jean-Pierre Lasota +1
We review our current knowledge of thermal and viscous instabilities in accretion discs around compact objects. We begin with classical disc models based on analytic viscosity pres…
X-ray Variability and Photosphere Evolution during Accretion Disk Formation in Tidal Disruption Events
Xiaoshan Huang, Maria Renee Meza, Sol Bin Yun +3
The early time emission in tidal disruption events (TDEs) originates from both accretion and shocks, which produce photons that eventually emerge from an inhomogeneous photosphere.…
Radiation Hydrodynamic Simulations of Low-Energy Explosions of Red and Yellow Supergiants
Andrea Antoni, Yan-Fei Jiang, Eliot Quataert
A variety of physical processes leads to the low-energy ejection of material from the hydrogen-rich envelopes of red and yellow supergiants. These include common envelope events, s…
