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…

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…

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…

X-Ray Bright Active Galactic Nuclei in Local Dwarf Galaxies: Insights from eROSITA

Andrea Sacchi, Akos Bogdan, Urmila Chadayammuri +1

Although supermassive black holes (SMBHs) reside in the heart of virtually every massive galaxy, it remains debated whether dwarf galaxies commonly host SMBHs. Because low-mass gal…
