Strongly Magnetized Super-Eddington Accretion: How Spin and Accretion Rate Regulate Energy Output and Mass Loss
Tom Man Kwan, Lixin Dai, Cheuk Kwan Kan +5
Strongly magnetized super-Eddington accretion flows power many important astrophysical systems, but how black hole parameters control their output is unclear. We present 32 general…
Diverse Emission Patterns from Precessing Super-Eddington Disks Formed in Tidal Disruption Events
Jin-Hong Chen, Lixin Dai, Kan Cheuk Kwan +2
A tidal disruption event (TDE) occurs when a star passes within the tidal radius of a supermassive black hole (SMBH). In TDEs it is expected that the orbital angular momentum of th…
QPEs as Lense-Thirring precession of super-Eddington flows
M. Middleton, A. Gurpide, T. M. Kwan +9
Quasi-periodic eruptions (QPEs) are a recently identified class of X-ray transient associated with tidal disruption events by supermassive black holes, and for which there are mult…
Formation of Wind-Fed Black Hole High-mass X-ray Binaries: The Role of Roche-lobe-Overflow Post Black-Hole Formation
Zepei Xing, Tassos Fragos, Emmanouil Zapartas +12
The three dynamically confirmed wind-fed black hole high-mass X-ray binaries (BH-HMXBs) are suggested to all contain a highly spinning black hole (BH). However, based on the theori…
Sub-relativistic Outflow and Hours-Timescale Large-amplitude X-ray Dips during Super-Eddington Accretion onto a Low-mass Massive Black Hole in the Tidal Disruption Event AT2022lri
Yuhan Yao, Muryel Guolo, Francesco Tombesi +32
We present the tidal disruption event (TDE) AT2022lri, hosted in a nearby ( Mpc) quiescent galaxy with a low-mass massive black hole ($10^4\,M_\odot < M_{\rm BH} < 10…
The Effects of Gas Angular Momentum on the Formation of Magnetically Arrested Disks and the Launching of Powerful Jets
Tom M. Kwan, Lixin Dai, Alexander Tchekhovskoy
In this letter, we investigate Bondi-like accretion flows with zero or low specific angular momentum by performing 3D general relativistic magnetohydrodynamic simulations. In order…
The properties of wind and jet from a super-Eddington accretion flow around a supermassive black hole
Hai Yang, Feng Yuan, Tom Kwan +1
Wind and jet are important medium of AGN feedback thus it is crucial to obtain their properties for the feedback study. In this paper we investigate the properties of wind and jet…
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…
