Abstract The Laser Interferometer Space Antenna (LISA) will be a transformative experiment
for gravitational wave astronomy, and, as such, it will offer unique opportunities to address …

In this article, we provide a review of the current state of the research of the black hole
shadow, focusing on analytical (as opposed to numerical and observational) studies. We …

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 …

Horizon-scale images of black holes (BHs) and their shadows have opened an
unprecedented window onto tests of gravity and fundamental physics in the strong-field …

Abstract CASA, the Common Astronomy Software Applications, is the primary data
processing software for the Atacama Large Millimeter/submillimeter Array (ALMA) and the …

In this paper we provide a first physical interpretation for the Event Horizon Telescopeʼs
(EHT) 2017 observations of Sgr A*. Our main approach is to compare resolved EHT data at …

In this paper we quantify the temporal variability and image morphology of the horizon-scale
emission from Sgr A*, as observed by the EHT in 2017 April at a wavelength of 1.3 mm. We …
