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…
A High-Frequency Doppler Feature in the Power Spectra of Simulated GRMHD Black Hole Accretion Disks
Sarah Wellons, Yucong Zhu, Dimitrios Psaltis +2
Black hole binaries exhibit a wide range of variability phenomena, from large-scale state changes to broadband noise and quasi-periodic oscillations, but the physical nature of muc…
Radio Observations Reveal Unusual Circumstellar Environments for Some Type Ibc Supernova Progenitors
Sarah Wellons, Alicia M. Soderberg, Roger A. Chevalier
We present extensive radio observations of the nearby Type Ibc supernovae 2004cc, 2004dk, and 2004gq spanning 8-1900 days after explosion. Using a dynamical model developed for syn…
