Demographics of black holes at 100 R scales: accretion flows, jets, and shadows

Dhanya G. Nair, Neil M. Nagar, Venkatessh Ramakrishnan +87

Using the Event Horizon Telescope (EHT), the gravitationally lensed rings around the supermassive black holes (SMBHs) in Messier 87 (M87) and Sagittarius A* (Sgr A*) have now been…

Machine- and deep-learning-driven angular momentum inference from BHEX observations of the photon ring

Joseph R. Farah, Jordy Davelaar, Daniel Palumbo +2

The photon ring is an important probe of black hole (BH) properties and will be resolved by the Black Hole Explorer (BHEX) for the first time. However, extraction of black ho…

Prospects of Detecting a Jet in Sagittarius A* with VLBI

Erandi Chavez, Sara Issaoun, Michael D. Johnson +3

Event Horizon Telescope (EHT) images of the horizon-scale emission around the Galactic Center supermassive black hole Sagittarius A* (Sgr A*) favor accretion flow models with a jet…
