Afterglows from binary neutron star post-merger systems embedded in AGN disks
Adithan Kathirgamaraju, Hui Li, Benjamin R. Ryan +1
The observability of afterglows from binary neutron star mergers, occurring within AGN disks is investigated. We perform 3D GRMHD simulations of a post-merger system, and follow th…
PATOKA: Simulating Electromagnetic Observables of Black Hole Accretion
George N. Wong, Ben S. Prather, Vedant Dhruv +11
The Event Horizon Telescope (EHT) has released analyses of reconstructed images of horizon-scale millimeter emission near the supermassive black hole at the center of the M87 galax…
Radiation GRMHD simulations of M87: funnel properties and prospects for gap acceleration
Philippe Z. Yao, Jason Dexter, Alexander Y. Chen +2
We use the public code ebhlight to carry out 3D radiative general relativistic magnetohydrodynamics (GRMHD) simulations of accretion onto the supermassive black hole in M87. The si…
Pair Drizzle around Sub-Eddington Supermassive Black Holes
George N. Wong, Benjamin R. Ryan, Charles F. Gammie
Electron-positron pair creation near sub-Eddington accretion rate black holes is believed to be dominated by the Breit-Wheeler process (photon-photon collisions). The interacting h…
Monitoring the Morphology of M87* in 2009-2017 with the Event Horizon Telescope
Maciek Wielgus, Kazunori Akiyama, Lindy Blackburn +26
The Event Horizon Telescope (EHT) has recently delivered the first resolved images of M87*, the supermassive black hole in the center of the M87 galaxy. These images were produced…
Bremsstrahlung in GRMHD models of accreting black holes
R. Yarza, G. N. Wong, B. R. Ryan +1
The role of bremsstrahlung in the emission from hot accretion flows around slowly accreting supermassive black holes is not thoroughly understood. In order to appraise the importan…
