Gravitational Test Beyond the First Post-Newtonian Order with the Shadow of the M87 Black Hole

Dimitrios Psaltis, Lia Medeiros, Pierre Christian +185

The 2017 Event Horizon Telescope (EHT) observations of the central source in M87 have led to the first measurement of the size of a black-hole shadow. This observation offers a new…

Monitoring the Morphology of M87* in 2009-2017 with the Event Horizon Telescope

Maciek Wielgus, Kazunori Akiyama, Lindy Blackburn +26

The Event Horizon Telescope (EHT) has recently delivered the first resolved images of M87*, the supermassive black hole in the center of the M87 galaxy. These images were produced…

A coupled guiding center-Boris particle pusher for magnetized plasmas in compact-object magnetospheres

Fabio Bacchini, Bart Ripperda, Alexander A. Philippov +1

We present a novel numerical scheme for simulating the motion of relativistic charged particles in magnetospheres of compact objects, typically filled with highly magnetized collis…

Magnetic Reconnection and Hot Spot Formation in Black Hole Accretion Disks

Bart Ripperda, Fabio Bacchini, Alexander Philippov

Hot spots, or plasmoids, forming due to magnetic reconnection in current sheets, are conjectured to power frequent X-ray and near-infrared flares from Sgr A*, the black hole in the…
