An End-to-End Numerical Framework for Tidal Disruption Events with AthenaK
Hong-Xuan Jiang, Mengqi Yang, David A. Velasco-Romero +4
In a tidal disruption event (TDE), a black hole (BH) tears apart a star, whose bound debris returns over many orbits to form an accretion disk. We present a framework built on the…

Magnetic Configuration Imprints on Quasi-Periodic Variability in GRMHD Simulations of Thin Accretion Disks
Jing-Ze Xia, Hong-Xuan Jiang, Indu K. Dihingia +1
The origin of quasi-periodic oscillations (QPOs) in black hole accretion flow remains uncertain, particularly regarding the role of magnetic field configurations in shaping disk st…

Dynamics and Radiative Signatures of Accretion Flows onto a Kerr-like Wormhole
Jing-ze Xia, Hong-xuan Jiang, Cheng Liu +1
Wormholes are a hypothetical object that connects disparate points in spacetime. It is a theoretically well-motivated black hole alternative and offers a potential observationally…
