From Feast to Famine: A Systematic Study of Accretion onto Oblique Pulsars with 3D GRMHD Simulations
Ariadna Murguia-Berthier, Kyle Parfrey, Alexander Tchekhovskoy +1
Disk-fed accretion onto neutron stars can power a wide range of astrophysical sources ranging from X-ray binaries, to accretion powered millisecond pulsars, ultra-luminous X-ray so…
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…
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…
Angular Momentum Loss During Stable Mass Transfer onto a Compact object: the Effect of Mass Loss via Accretion Disk Winds
Monica Gallegos-Garcia, Jonatan Jacquemin-Ide, Vicky Kalogera
We use an analytic framework to calculate the evolution of binary orbits under a physically-motivated model that accounts for angular momentum loss associated with winds from an ac…
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…
Collapsar Gamma-ray Bursts Grind their Black Hole Spins to a Halt
Jonatan Jacquemin-Ide, Ore Gottlieb, Beverly Lowell +1
The spin of a newly formed black hole (BH) at the center of a massive star evolves from its natal value due to two competing processes: accretion of gas angular momentum that incre…
Collapsar Black Holes are Likely Born Slowly Spinning
Ore Gottlieb, Jonatan Jacquemin-Ide, Beverly Lowell +2
Collapsing stars constitute the main black hole (BH) formation channel, and are occasionally associated with the launch of relativistic jets that power -ray bursts (GRBs). Thus…
Rapid Black Hole Spin-down by Thick Magnetically Arrested Disks
Beverly Lowell, Jonatan Jacquemin-Ide, Alexander Tchekhovskoy +1
Black hole (BH) spin can play an important role in galaxy evolution by controlling the amount of energy and momentum ejected from near the BH into the surroundings. We focus on rad…
