Impact of anisotropic ejecta on jet dynamics and afterglow emission in binary neutron-star mergers

Vasilis Mpisketzis, Raphaël Duqué, Antonios Nathanail +2

Binary neutron stars mergers widely accepted as potential progenitors of short gamma-ray bursts. After the remnant of the merger has collapsed to a black hole, a jet is powered and…

First M87 Event Horizon Telescope Results. IX. Detection of Near-horizon Circular Polarization

The Event Horizon Telescope Collaboration

Event Horizon Telescope (EHT) observations have revealed a bright ring of emission around the supermassive black hole at the center of the M87 galaxy. EHT images in linear polariza…

Polarimetric Geometric Modeling for mm-VLBI Observations of Black Holes

Freek Roelofs, Michael D. Johnson, Andrew Chael +4

The Event Horizon Telescope (EHT) is a millimeter very long baseline interferometry (VLBI) array that has imaged the apparent shadows of the supermassive black holes M87* and Sagit…

Future Prospects for Constraining Black-Hole Spacetime: Horizon-scale Variability of Astrophysical Jet

Kotaro Moriyama, Alejandro Cruz-Osorio, Yosuke Mizuno +3

The Event Horizon Telescope (EHT) Collaboration has recently published the first horizon-scale images of the supermassive black holes M87* and Sgr A* and provided some first inform…

First Sagittarius A* Event Horizon Telescope Results. VI: Testing the Black Hole Metric

The Event Horizon Telescope Collaboration

Astrophysical black holes are expected to be described by the Kerr metric. This is the only stationary, vacuum, axisymmetric metric, without electromagnetic charge, that satisfies…

First Sagittarius A* Event Horizon Telescope Results. III: Imaging of the Galactic Center Supermassive Black Hole

The Event Horizon Telescope Collaboration

We present the first event-horizon-scale images and spatiotemporal analysis of Sgr A* taken with the Event Horizon Telescope in 2017 April at a wavelength of 1.3 mm. Imaging of Sgr…
