After decades of fast-paced technical advances, optical/infrared (O/IR) interferometry has
seen a revolution in recent years:▪ The GRAVITY instrument at the Very Large Telescope …

We report on the polarized light curves of the Galactic Center supermassive black hole
Sagittarius A*, obtained at millimeter wavelength with the Atacama Large Millimeter …

Abstract The Event Horizon Telescope (EHT) Collaboration recently published the first
images of the supermassive black holes in the cores of the Messier 87 and Milky Way …

We present new astrometric and polarimetric observations of flares from Sgr A* obtained
with GRAVITY, the near-infrared interferometer at ESO's Very Large Telescope …

Hot spots, or plasmoids, which form 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 …

In this work we analyze the observational properties of incompressible relativistic fluid
spheres with and without thin-shells when surrounded by thin accretion disks. We consider a …

Pushed by a number of advances, electromagnetic observatories have now reached the
horizon scale of supermassive black holes. The existence and properties of horizons in our …

Large-amplitude Sgr A* near-infrared (NIR) flares result from energy injection into electrons
near the black hole event horizon. Astrometry data show continuous rotation of the emission …

We have performed a series of two-dimensional two-temperature general relativistic
magnetohydrodynamic simulations of magnetized accretion flows initiated from tori with …
