A Semi-analytical Model for Stellar Evolution in AGN Disks by Alexander J. Dittmann, Matteo Cantiello

“…Disks of gas accreting onto supermassive black holes may host numerous stellar-mass objects, formed within the disk or captured from a nuclear star cluster. …”

What Drives the H i Content of Central Galaxies—A Comparison between Hydrodynamic Simulations and Observations Using Random Forest by Xiao Li, Cheng Li, H. J. Mo

“…Beyond that, the accretion rate of supermassive black holes is the most important feature in TNG, while specific star formation rate is the top ranked in EAGLE. …”

Rates of Stellar Tidal Disruption Events around Intermediate-mass Black Holes by Janet N. Y. Chang, Lixin Dai, Hugo Pfister, Rudrani Kar Chowdhury, Priyamvada Natarajan

“…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. …”

Radiative properties and QPOs around charged black hole in Kalb–Ramond gravity by Shokhzod Jumaniyozov, Muhammad Zahid, Mirzabek Alloqulov, Inomjon Ibragimov, Javlon Rayimbaev, Sardor Murodov

“…We also obtain constrain values for the black hole mass, charge, KR field parameter, and QPO orbits found using Markovian chain Monte Carlo (MCMC) simulations for stellar mass (XTE J1550, GRS 1915+105), intermediate mass (M82-X1), and supermassive black holes (Sgr A*). Finally, we explore the radiative properties of the accretion disk around the charged black hole in KR gravity, such as the total radiation flux, accretion disc temperature, and differential luminosity.…”

Assessing the Dark Matter Content of Two Quasar Host Galaxies at z ∼ 6 through Gas Kinematics by Qinyue Fei, John D. Silverman, Seiji Fujimoto, Ran Wang, Luis C. Ho, Manuela Bischetti, Stefano Carniani, Michele Ginolfi, Gareth Jones, Roberto Maiolino, Wiphu Rujopakarn, N. M. Förster Schreiber, Juan M. Espejo Salcedo, L. L. Lee

“…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 by Nicholas Kaaz, Yoram Lithwick, Matthew Liska, Alexander Tchekhovskoy

“…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 by Dawid Brzeminski, Anson Hook, Junwu Huang, Clayton Ristow

“…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. …”
