Slow-Light Effect in the Jet-Launching Region of M87
Yuh Tsunetoe, Dominic W. Pesce, Ramesh Narayan
We explore the impact of "slow-light" radiative transfer - i.e., general relativistic radiative transfer (GRRT) calculations in which the simulated fluid evolves while light rays a…
Extreme magnetic fields around black holes
Koushik Chatterjee, Matthew Liska, Alexander Tchekhovskoy +2
Recent results of the event horizon-scale images of M87* and Sagittarius A* from the Event Horizon Telescope Collaboration show that strong magnetic fields are likely present aroun…
Accessing a New Population of Supermassive Black Holes with Extensions to the Event Horizon Telescope
Xinyue Alice Zhang, Angelo Ricarte, Dominic W. Pesce +6
The Event Horizon Telescope has produced resolved images of the supermassive black holes Sgr A* and M87*, which present the largest shadows on the sky. In the next decade, technolo…
Limb-Brightened Jet in M87 from Anisotropic Nonthermal Electrons
Yuh Tsunetoe, Dominic W. Pesce, Ramesh Narayan +5
Very long baseline interferometry observations reveal that relativistic jets like the one in M87 have a limb-brightened, double-edged structure. Analytic and numerical models strug…
Jet Archaeology and Forecasting: Image Variability and Magnetic Field Configuration
Yuh Tsunetoe, Ramesh Narayan, Angelo Ricarte
We investigate how magnetic field variations around accreting black holes on event horizon scales affect the morphology of magnetically-driven jet on larger scales. By performing r…
Bridging Scales in Black Hole Accretion and Feedback: Magnetized Bondi Accretion in 3D GRMHD
Hyerin Cho, Ben S. Prather, Ramesh Narayan +4
Fueling and feedback couple supermassive black holes (SMBHs) to their host galaxies across many orders of magnitude in spatial and temporal scales, making this problem notoriously…
