Shadow size for the supermassive black hole at the Galactic Center |
|
Abstract |
We discuss a shadow concept introduced by Falcke, Melia and Agol. We present estimates of shadow sizes for different parameters of black hole at the Galactic Center. We discuss results of observations of the smallest spot at the Galactic Center and their connections with the shadow size. We describe analytical dependences of shadow sizes as functions of charge and cosmological constant and discuss opportunity to get better fits with anti-de-Sitter or Reissner -- Nordstrom black hole models. |
