Misaligned magnetized accretion flows onto spinning black holes: Magneto-spin alignment, outflow power, and intermittent jets
Koushik Chatterjee, Nicholas Kaaz, Matthew Liska +2
Magnetic fields regulate black hole (BH) accretion, governing both inflow and outflow dynamics. When a BH accumulates substantial vertical magnetic flux, it enters the magnetically…
Magnetorotational dynamo can generate large-scale vertical magnetic fields in 3D GRMHD simulations of accreting black holes
Jonatan Jacquemin-Ide, François Rincon, Alexander Tchekhovskoy +1
Jetted astrophysical phenomena with black hole (BH) engines, including binary mergers, jetted tidal disruption events, and X-ray binaries, require a large-scale vertical magnetic f…
How to Turn Jets into Cylinders near Supermassive Black Holes in 3D GRMHD Simulations
Valeriia Rohoza, Aretaios Lalakos, Max Paik +4
Accreting supermassive black holes (SMBHs) produce highly magnetized relativistic jets that tend to collimate gradually as they propagate outward. However, recent radio interferome…
Synchrotron polarization signatures of surface waves in supermassive black hole jets
Jordy Davelaar, Bart Ripperda, Lorenzo Sironi +7
Supermassive black holes in active galactic nuclei (AGN) are known to launch relativistic jets, which are observed across the entire electromagnetic spectrum and are thought to be…
Jets with a Twist: Emergence of FR0 Jets in 3D GRMHD Simulation of Zero Angular Momentum Black Hole Accretion
Aretaios Lalakos, Alexander Tchekhovskoy, Omer Bromberg +4
Spinning supermassive black holes (BHs) in active galactic nuclei (AGN) magnetically launch relativistic collimated outflows, or jets. Without angular momentum supply, such jets ar…
Winds and Disk Turbulence Exert Equal Torques on Thick Magnetically Arrested Disks
Vikram Manikantan, Nicholas Kaaz, Jonatan Jacquemin-Ide +4
The conventional accretion disk lore is that magnetized turbulence is the principal angular momentum transport process that drives accretion. However, when dynamically important la…
Large-scale Evolution of Seconds-long Relativistic Jets from Black Hole-Neutron Star Mergers
Ore Gottlieb, Danat Issa, Jonatan Jacquemin-Ide +11
We present the first numerical simulations that track the evolution of a black hole-neutron star (BH-NS) merger from pre-merger to . The disk that forms…
Hours-long Near-UV/Optical Emission from Mildly Relativistic Outflows in Black Hole-Neutron Star Mergers
Ore Gottlieb, Danat Issa, Jonatan Jacquemin-Ide +7
The ongoing LIGO-Virgo-KAGRA observing run O4 provides an opportunity to discover new multi-messenger events, including binary neutron star (BNS) mergers such as GW170817, and the…
The EB-correlation in Resolved Polarized Images: Connections to Astrophysics of Black Holes
Razieh Emami, Sheperd S. Doeleman, Maciek Wielgus +18
We present an in-depth analysis of a newly proposed correlation function in visibility space, between the E and B modes of the linear polarization, hereafter the EB-correlation, fo…
Millimeter Observational Signatures of Flares in Magnetically Arrested Black Hole Accretion Models
He Jia, Bart Ripperda, Eliot Quataert +4
In general relativistic magneto-hydrodynamic (GRMHD) simulations, accreted magnetic flux on the black hole horizon episodically decays, during which magnetic reconnection heats up…
