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…

Demystifying flux eruptions: Magnetic flux transport in magnetically arrested disks

Jonatan Jacquemin-Ide, Mitchell C. Begelman, Beverly Lowell +3

Magnetically arrested disks (MADs) are a compelling model for explaining variability in low-luminosity active galactic nuclei (AGN), including horizon-scale outbursts like those ob…

Modelling the Future of Gaia Neutron Star-Main Sequence Binaries: From Eccentric Orbits to Millisecond Pulsar-White Dwarfs

Debatri Chattopadhyay, Kyle A. Rocha, Seth Gossage +3

We model the evolution of 21 Gaia neutron star (NS)-main-sequence binaries (orbital period -- days, eccentricity ) using binary evolutio…

Universal Radial Scaling of Large-Scale Black Hole Accretion for Magnetically Arrested And Rocking Accretion Disks

Aretaios Lalakos, Alexander Tchekhovskoy, Elias R. Most +3

Accretion onto supermassive black holes (BHs) can launch relativistic jets that inject energy and momentum into their surroundings. Understanding how such feedback shapes large-sca…

Black hole spectral states revealed in GRMHD simulations with texture memory accelerated cooling

Pedro Naethe Motta, Jonatan Jacquemin-Ide, Rodrigo Nemmen +2

X-ray binaries (XRBs) display spectral state transitions that are accompanied by substantial changes in the hardness, luminosity, and structure of the accretion flow. We developed…

Black Hole Spin-down in Collapsars in 3D Neutrino Transport GRMHD Simulations

Danat Issa, Beverly Lowell, Jonatan Jacquemin-Ide +2

Collapsars -- massive stars whose cores promptly collapse into black holes (BHs) -- can power long-duration gamma-ray bursts (LGRBs) via relativistic, collimated, electromagnetical…
