The Cosmic History of Black Hole Growth from Deep Multiwavelength Surveys by Ezequiel Treister, C. Megan Urry

“…Significant progress has been made in the last few years on understanding how supermassive black holes form and grow. In this paper, we begin by reviewing the spectral signatures of active galactic nuclei (AGN) ranging from radio to hard X-ray wavelengths. …”

Can the New Neutrino Telescopes Reveal the Gravitational Properties of Antimatter? by Dragan Slavkov Hajdukovic

“…Our simplified calculations suggest that the antineutrinos emitted by supermassive black holes in the centre of the Milky Way and Andromeda Galaxy could be detected by the new generation of neutrino telescopes.…”

Intermediate Mass Black Holes: Their Motion and Associated Energetics by C. Sivaram, Kenath Arun

“…We also consider their formation in the early universe and also discuss the possibility of supermassive black holes forming from mergers of several IMBH and compare the relevant time scales involved with other scenarios.…”

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.…”

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. …”

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. …”

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. …”

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.…”

Dark matter annihilation via Breit-Wigner enhancement with heavier mediator by Yu Cheng, Shao-Feng Ge, Jie Sheng, Tsutomu T. Yanagida

“…We propose a new scenario that both the dark matter freeze-out in the early Universe and its possible annihilation for indirect detection around a supermassive black hole are enhanced by a Breit-Wigner resonance. …”

Relativistic Einstein rings of Reissner–Nordström black holes nonminimally coupled to electrodynamics by Rodrigo Maier

Constraining Binary Mergers in Active Galactic Nuclei Disks Using the Nonobservation of Lensed Gravitational Waves by Samson H. W. Leong, Justin Janquart, Aditya Kumar Sharma, Paul Martens, Parameswaran Ajith, Otto A. Hannuksela

“…We show that a considerable fraction of the BBH in AGN disks will be strongly lensed by the central supermassive black hole (SMBH). Thus, the nonobservation of lensed GW signals can be used to constrain the fraction of BBH binaries residing in AGN disks. …”
