Rates of Stellar Tidal Disruption Events around Intermediate-mass Black Holes
Published 2025-01-01“…Rates of stellar tidal disruption events (TDEs) around supermassive black holes (SMBHs) have been extensively calculated using the loss cone theory, while theoretical work on TDE rates around intermediate-mass black holes (IMBHs) has been lacking. …”

Assessing the Dark Matter Content of Two Quasar Host Galaxies at z ∼ 6 through Gas Kinematics
Published 2025-01-01“…Notably, while the masses of these supermassive black holes (SMBHs) are approximately 1 dex higher than the low-redshift relationship with stellar mass, the closer alignment of SMBH and halo masses with a local relationship may indicate that the early formation of these SMBHs is linked to their dark matter halos, providing insights into the coevolution of galaxies and black holes in the early Universe.…”

Extreme Scale Height Variations and Nozzle Shocks in Warped Disks
Published 2025-01-01“…Accretion disks around both stellar-mass and supermassive black holes (BHs) are likely often warped. Whenever a disk is warped, its scale height varies with azimuth. …”

Searching for string bosenovas with gravitational wave detectors
Published 2025-01-01“…During the superradiance growth of a dark photon cloud — which occurs for dark photon masses m A ′ ~ 10 − 14 − 10 − 11 eV $$ {m}_{A^{\prime }}\sim {10}^{-14}-{10}^{-11}\textrm{eV} $$ around stellar-mass black holes ( m A ′ ~ 10 − 23 − 10 − 16 eV $$ {m}_{A^{\prime }}\sim {10}^{-23}-{10}^{-16}\textrm{eV} $$ for supermassive black holes) — the dark electromagnetic field might reach a critical field strength, when a network of dark photon strings is produced via a superheated phase transition. …”
