SUPERMASSIVE BLACK HOLE AT THE GALACTIC CENTER
New Results and Actual Problems in Particle & Astroparticle Physics and Cosmology, 2014 We derive an analytical expression of a shadow size as a function of a charge in the Reissner - Nordstr?m (RN) metric. Using the derived expression we consider shadows for negative tidal charges and charges corresponding to naked singularities q=Q2/M2>1, where Q and M are black hole charge and mass, respectively.

Supermassive black holes : the local supermassive black hole mass function
, 2012 Over recent years there has been an increase of the number of secure supermassive black hole (SMBH) detections. These SMBH measurements have lead astronomers to establish well defined empirical relationships between the SMBH mass and some of the properties of the host galaxy.
