Black hole pulsars and monster shocks as outcomes of black hole--neutron star mergers

Yoonsoo Kim, Elias R. Most, Andrei M. Beloborodov +1

The merger of a black hole (BH) and a neutron star (NS) in most cases is expected to leave no material around the remnant BH; therefore, such events are often considered as sources…

Bulk Motions in the Black Hole Jet Sheath as a Candidate for the Comptonizing Corona

Navin Sridhar, Bart Ripperda, Lorenzo Sironi +2

Using two-dimensional general relativistic resistive magnetohydrodynamic simulations, we investigate the properties of the sheath separating the black hole jet from the surrounding…

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)…

A New Particle Pusher with Hadronic Interactions for Modeling Multimessenger Emission from Compact Objects

Minghao Zou, Hayk Hakobyan, Rostom Mbarek +3

We propose novel numerical schemes based on the Boris method in curved spacetime, incorporating both hadronic and radiative interactions for the first time. Once the proton has los…

Dual Jet Interaction, Magnetically Arrested Flows, and Flares in Accreting Binary Black Holes

Sean M. Ressler, Luciano Combi, Bart Ripperda +1

Supermassive binary black holes in galactic centers are potential multimessenger sources in gravitational waves and electromagnetic radiation. To find such objects, isolating uniqu…

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…
