Explaining the X-ray Precursor, Ultra-long Prompt Emission, and Week-long Decay of GRB250702B with a Jetted Micro-TDE
Fulya Kıroğlu, Taeho Ryu, Alexander Tchekhovskoy +3
The longest detected gamma-ray burst, GRB250702B, exhibited seven hours of prompt -ray emission, preceded by a soft X-ray precursor ( day earlier) and followed by a weeks…
Thick Disks, Thin Hopes: Suppressed Capture and Merger Rates in AGN
Yashvardhan Tomar, Philip F. Hopkins, Kyle Kremer
Multiple models have been suggested over the years to explain the structure and support of accretion disks around supermassive black holes, from the standard thin thermal-pressure-…
Connecting Cores and Black Hole Dynamics Across Scales: From Globular Clusters to Massive Ellipticals
Kyle Kremer, Newlin C. Weatherford, Philip F. Hopkins +2
The centers of massive elliptical galaxies exhibit a wide range in density profiles, from central cusps to resolved cores with order kiloparsec sizes. The cored ellipticals have be…
Compact Objects in Globular Clusters
Kyle Kremer
It is now widely established that globular clusters host robust populations of white dwarfs, neutron stars, and black holes throughout their lifetimes. Within clusters, dynamical p…
Zooming In On The Multi-Phase Structure of Magnetically-Dominated Quasar Disks: Radiation From Torus to ISCO Across Accretion Rates
Philip F. Hopkins, Kung-Yi Su, Norman Murray +12
Recent radiation-thermochemical-magnetohydrodynamic simulations resolved formation of quasar accretion disks from cosmological scales down to ~300 gravitational radii , argu…
From Seeds to Supermassive Black Holes: Capture, Growth, Migration, and Pairing in Dense Proto-Bulge Environments
Yanlong Shi, Kyle Kremer, Philip F. Hopkins
The origins and mergers of supermassive black holes (BHs) remain a mystery. We describe a scenario from a novel multi-physics simulation featuring rapid (Myr) hyper-E…
Feedback-regulated Seed Black Hole Growth in Star-Forming Molecular Clouds and Galactic Nuclei
Yanlong Shi, Kyle Kremer, Philip F. Hopkins
The detection of supermassive black holes (SMBHs) in high-redshift luminous quasars may require a phase of rapid accretion, and as a precondition, substantial gas influx toward see…
FORGE'd in FIRE III: The IMF in Quasar Accretion Disks from STARFORGE
Philip F. Hopkins, Michael Y. Grudic, Kyle Kremer +3
Recently, we demonstrated self-consistent formation of strongly-magnetized quasar accretion disks (QADs) from cosmological radiation-magnetohydrodynamic-thermochemical galaxy-star…
An Analytic Model For Magnetically-Dominated Accretion Disks
Philip F. Hopkins, Jonathan Squire, Eliot Quataert +6
Recent numerical cosmological radiation-magnetohydrodynamic-thermochemical-star formation simulations have resolved the formation of quasar accretion disks with Eddington or super-…
FORGE'd in FIRE II: The Formation of Magnetically-Dominated Quasar Accretion Disks from Cosmological Initial Conditions
Philip F. Hopkins, Jonathan Squire, Kung-Yi Su +9
In a companion paper, we reported the self-consistent formation of quasar accretion disks with inflow rates down to <300 Schwarzschild radii fro…
