Two-temperature treatments in magnetically arrested disk GRMHD simulations more accurately predict light curves of Sagittarius A*
León Salas, Matthew Liska, Sera Markoff +6
The Event Horizon Telescope Collaboration (EHTC) observed the Galactic centre source Sagittarius A* (Sgr A*) and used emission models primarily based on single ion temperature (1T)…
Magnetically-Driven Neutron-Rich Ejecta Unleashed: Global 3D Neutrino-General Relativistic Magnetohydrodynamic Simulations of Collapsars Probe the Conditions for r-process Nucleosynthesis
Danat Issa, Ore Gottlieb, Brian Metzger +5
Collapsars - rapidly rotating stellar cores that form black holes - can power gamma-ray bursts (GRBs) and are proposed to be key contributors to the production of heavy elements in…
H-AMR FORGE'd in FIRE I: Magnetic state transitions, jet launching and radiative emission in super-Eddington, highly magnetized quasar disks formed from cosmological initial conditions
Nicholas Kaaz, Matthew Liska, Alexander Tchekhovskoy +2
Quasars are powered by supermassive black hole (SMBH) accretion disks, yet standard disk models are inconsistent with many quasar observations. Recently, Hopkins et al. (2024) simu…
Extreme scale height variations and nozzle shocks in warped disks
Nicholas Kaaz, Yoram Lithwick, Matthew Liska +1
Accretion disks around both stellar-mass and supermassive black holes are likely often warped. Whenever a disk is warped, its scale height varies with azimuth. Sufficiently strong…
Strongly magnetized accretion with low angular momentum produces a weak jet
Alisa Galishnikova, Alexander Philippov, Eliot Quataert +2
We study the spherical accretion of magnetized plasma with low angular momentum onto a supermassive black hole, utilizing global general relativistic magnetohydrodynamic simulation…
Extreme magnetic fields around black holes
Koushik Chatterjee, Matthew Liska, Alexander Tchekhovskoy +2
Recent results of the event horizon-scale images of M87* and Sagittarius A* from the Event Horizon Telescope Collaboration show that strong magnetic fields are likely present aroun…
Resolution analysis of magnetically arrested disk simulations
León Salas, Gibwa Musoke, Koushik Chatterjee +4
Polarisation measurements by the Event Horizon Telescope from M87 and Sgr A suggest that there is a dynamically strong, ordered magnetic field, typical of what is e…
Tilted Accretion Disks
P. Chris Fragile, Matthew Liska
In this chapter, we review some of the interesting consequences that tilt between the spin axis of the black hole and angular momentum axis of the accretion disk can have on the dy…
