Understanding the behavior of energy X-rays from the black hole candidate GRS 1915+105

Abstract

Black Hole candidate GRS 1915+105 shows a very interesting behaviour at high energy X-rays. For instance, it shows quasi-Periodic Oscillations (QPO) only at high energies. Also the spectral slopes at high energies vary and carry information about the winds and jets produced at the centrifugal barrier. We discuss these aspects of the observations with explanation from the present theoretical models.
