The Variability of the Black-Hole Image in M87 at the Dynamical Time Scale

Kaushik Satapathy, Dimitrios Psaltis, Feryal Ozel +235

The black-hole images obtained with the Event Horizon Telescope (EHT) are expected to be variable at the dynamical timescale near their horizons. For the black hole at the center o…

Toward determining the number of observable supermassive black hole shadows

Dominic W. Pesce, Daniel C. M. Palumbo, Ramesh Narayan +7

We present estimates for the number of shadow-resolved supermassive black hole (SMBH) systems that can be detected using radio interferometers, as a function of angular resolution,…

The Polarized Image of a Synchrotron Emitting Ring of Gas Orbiting a Black Hole

Ramesh Narayan, Daniel C. M. Palumbo, Michael D. Johnson +237

Synchrotron radiation from hot gas near a black hole results in a polarized image. The image polarization is determined by effects including the orientation of the magnetic field i…

First M87 Event Horizon Telescope Results. VIII. Magnetic Field Structure near The Event Horizon

The Event Horizon Telescope Collaboration

Event Horizon Telescope (EHT) observations at 230 GHz have now imaged polarized emission around the supermassive black hole in M87 on event-horizon scales. This polarized synchrotr…

First M87 Event Horizon Telescope Results. VII. Polarization of the Ring

The Event Horizon Telescope Collaboration

In 2017 April, the Event Horizon Telescope (EHT) observed the near-horizon region around the supermassive black hole at the core of the M87 galaxy. These 1.3 mm wavelength observat…
