Modeling Reconstructed Images of Jets Launched by SANE Super-Eddington Accretion Flows Around SMBHs with the ngEHT
Brandon Curd, Razieh Emami, Freek Roelofs +1
Tidal disruption events (TDEs) around super massive black holes (SMBHs) are a potential laboratory to study super-Eddington accretion disks and sometimes result in powerful jets or…
Tracing the hot spot motion using the next generation Event Horizon Telescope (ngEHT)
Razieh Emami, Paul Tiede, Sheperd S. Doeleman +19
We propose to trace the dynamical motion of a shearing hot spot near the SgrA* source through a dynamical image reconstruction algorithm, StarWarps. Such a hot spot may form as the…
Probing plasma composition with the next generation Event Horizon Telescope (ngEHT)
Razieh Emami, Richard Anantua, Angelo Ricarte +15
We explore the plasma matter content in the innermost accretion disk/jet in M87* as relevant for an enthusiastic search for the signatures of anti-matter in the next generation of…
Emission Modeling in the EHT-ngEHT Age
Richard Anantua, Joaquín Dúran, Nathan Ngata +9
This work proposes a methodology to test phenomenologically-motivated emission processes that account for the flux and polarization distribution and global structure of the 230 GHz…
Unraveling Twisty Linear Polarization Morphologies in Black Hole Images
Razieh Emami, Angelo Ricarte, George N. Wong +23
We investigate general relativistic magnetohydrodynamic simulations (GRMHD) to determine the physical origin of the twisty patterns of linear polarization seen in spatially resolve…
The Photon Ring in M87*
Avery E. Broderick, Dominic W. Pesce, Paul Tiede +48
We report measurements of the gravitationally lensed secondary image -- the first in an infinite series of so-called "photon rings" -- around the supermassive black hole M87* via s…
