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…
Galaxy formation with wave/fuzzy dark matter: The core-halo structure and the solitonic imprint
Alvaro Pozo, Razieh Emami, Philip Mocz +9
Dark matter-dominated cores have long been claimed for the well-studied local group dwarf galaxies. More recently, extended stellar halos have been uncovered around several of thes…
On the Universality of Energy Extraction from Black Hole Spacetimes
Koushik Chatterjee, Ziri Younsi, Prashant Kocherlakota +1
The launching of astrophysical jets provides the most compelling observational evidence for direct extraction of black hole (BH) spin energy via the Blandford-Znajek (BZ) mechanism…
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…
