Modelling the flaring emission at the Galactic Centre

Research output: Chapter in Book/Report/Conference proceedingConference proceeding contribution

Abstract

The massive black hole at the Galactic Centre is known to be variable in radio, millimeter, near-IR and X-rays. We investigate the physical processes responsible for the variable observed emissions from the compact radio source, Sgr A*. We study the evolution of the variable emission region and present light curves and time-resolved spectra of emissions from the accretion disk, close to the event horizon, near the marginally stable orbit of a Kerr black hole.
