Magnetized accretion onto rapidly spinning binary black holes: mini-disk thermodynamics, magnetic transport, and dual jets
Luciano Combi, Manuela Campanelli, Sean M. Ressler +2
Supermassive binary black holes embedded in gas-rich environments are promising multi-messenger sources for pulsar timing arrays and future space-borne gravitational-wave interfero…
Observational Tests of Sgr A*'s State of the Accretion Flow
F. Yusef-Zadeh, R. G. Arendt, H. Bushouse +4
General relativistic magneto-hydrodynamic (GRMHD) simulations of the possibly magnetically arrested disk (MAD) of the accretion flow of Sgr A* predict short and long time variabili…
Modes in Transitional Millisecond Pulsars: Evidence of Pulsar Wind-Induced Disk Heating from GRMHD and Radiative Transfer
Raphaël Mignon-Risse, Manuel Linares, Kyle Parfrey +2
Transitional millisecond pulsars (tMSPs) alternate between radio and X-ray pulsar states, and can represent the missing link between rotation- and accretion-powered neutron stars.…
Constraining the Galactic Center Dark Cluster with ELT/MICADO Observations
Sebastiano D. von Fellenberg, Matúš Labaj, Sean M. Ressler
The Galactic Center hosts the densest known stellar environment in the Milky Way, dominated by the massive black hole Sgr A* and the surrounding nuclear star cluster. Theory predic…
Stellar-wind Fueled Accretion onto Sagittarius A* in the Presence of a Nuclear Star Cluster
Edward Skrabacz, Lena Murchikova, Sean M. Ressler +2
The Milky Way's Galactic Center hosts the black hole Sagittarius A* (Sgr A*), which provides us with a close-up view into supermassive black hole accretion and feedback. Recent wor…
