Shadow Cast of the Schwarzschild-like Black Holes

The Event Horizon Telescope has recently seen the edge of a black hole. This fruitful outcome reveals a fine structure near the black hole horizon. The photon ring and shadow have been clearly observed which provides us with a good opportunity to test general relativity in the regime of strong gravity. In this thesis first we study Schwarzschild black hole and its properties, then we calculate null geodesics of Schwarzschild metric from Euler-Lagrange to find its shadow cast which is two dimensional dark zone in the celestial sphere caused by the strong gravity of the black hole. Last, we study the shadow of the quantum corrected Schwarzschild black hole. Hence, we discuss the effect of the quantum on the shadow of the black hole.
