Change in Mass of Spinning Black Holes Due to Change in AngularMomentum

Abstract

The present paper reviews the change in mass of spinning black holes w.r.t. the angular momentum in AGN as proposed by Mahto, D. & Kumari, A. to show that the change in mass of spinning black holes due to change in the angular momentum decreases with increasing their masses for both categories of spin a*=1/2 & a*=1 in the same manner provided that the change in mass of spinning black holes w.r.t. the angular momentum for a*=1/2 is lesser than to that of spinning black holes of the same mass for a*=1.
