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, producing photons that eventually emerge from an inhomogeneous photosphere. We…
Radiation GRMHD Models of Accretion onto Stellar-Mass Black Holes: II. Super-Eddington Accretion
Lizhong Zhang, James M. Stone, Christopher J. White +3
We present a comprehensive analysis of super-Eddington black hole accretion simulations that solve the GRMHD equations coupled with angle-discretized radiation transport. The simul…
Perturbing AGN Accretion Disks with Stars and Moderately Massive Black Holes: Implications for Changing-Look AGN and Quasi-Periodic Eruptions
Sierra A. Dodd, Xiaoshan Huang, Shane W. Davis +1
We present a model that explains some extreme variability phenomena observed in active galactic nuclei (AGN). In this model, an orbiting companion interacts with the accretion disk…
Radiation GRMHD Models of Accretion onto Stellar-Mass Black Holes: I. Survey of Eddington Ratios
Lizhong Zhang, James M. Stone, Patrick D. Mullen +3
We summarize results from a survey of radiation-dominated black hole accretion flows across a wide range of mass accretion rates, as well as two values of black hole spin and initi…
Radiation-magnetohydrodynamic Simulations of Accretion Flow Formation After a Tidal Disruption Event
Maria Renee Meza, Xiaoshan Huang, Shane W. Davis +1
We perform 3D radiation-magnetohydrodynamic simulations of the evolution of the fallback debris after a tidal disruption event. We focus on studying the effects of magnetic fields…
Radiative magnetohydrodynamics simulation of minidisks in equal-mass massive black hole binaries
Chi-Ho Chan, Vishal Tiwari, Tamara Bogdanović +2
We are on the cusp of detecting gravitational waves (GWs) from individual massive black hole binaries (MBHBs) with the Laser Interferometer Space Antenna and pulsar-timing arrays.…
Disk draining in LIGO progenitor black hole binaries and its significance to electromagnetic counterparts
Xiaoshan Huang, Sierra Dodd, Sophie Lund Schrøder +2
The effect of tidal forces on transport within a relic accretion disk in binary black holes is studied here with a suite of two-dimensional hydrodynamic simulations. As the binary…
Pre-peak Emission in Tidal Disruption Events
Xiaoshan Huang, Shane W. Davis, Yan-fei Jiang
The rising part of a tidal disruption event light curve provides unique insight into early emission and the onset of accretion. Various mechanisms are proposed to explain the pre-p…
