Black holes are the most compact objects in the universe. Therefore, matter accreting onto them is likely to radiate photons of energy comparable to very high gravitational potential energy. We discuss the nature of the emitted radiation in X-rays and gamma-rays from black hole candidates. We present theoretical solutions, which comprise both Keplerian and sub-Keplerian components and suggest that shocks in accretion and outflows may play a major role in producing these spectra.

The Spectral Properties of Shocked Two-Component Accretion Flows in the Presence of Synchrotron Emission

Two-component advective flows have Keplerian accretion disks on the equatorial plane that is surrounded by sub-Keplerian transonic flows. In this Letter, we study the spectral properties of these

Sensitivity of Spectral and Temporal Properties of Accretion and Outflows on Space Time Geometry, Viscosity and Cooling

In this chapter, we describe the development of a radiation hydrodynamic simulation code and discuss the results obtained when we use it to study the dynamics of an accretion disk around a galactic



Fundamental States of Accretion/Jet Configuration and the Black Hole Candidate GRS1915+105

Advective disk paradigm of black hole accretion includes self-consistent formation of shocks and outflows from post-shock region. We apply this paradigm to understand rich variation of the light

Signature of Accretion Shocks in Emitted Radiation From a Two Temperature Advective Flows Around Black Holes

Centrifugal barrier supported boundary layer (CENBOL) of a black hole affects the spectrum exactly in the same way the boundary layer of a neutron star does. The CENBOL is produced due to standing or

Spectral Properties of Accretion Disks around Black Holes. II. Sub-Keplerian Flows with and without Shocks

Close to a black hole, the density of the sub-Keplerian accreting matter becomes higher compared with a spherical flow as a consequence of the presence of a centrifugal barrier, independently of

Radiative Processes, Spectral States and Variability of Black-Hole Binaries(Session 4 : Theoretical/Numerial Approaches to the Accretion Physics)

We review radiative processes responsible for X-ray emission in hard (low) and soft (high) spectral states of black-hole binaries. The main process in the hard state appears to be scattering of

Spectral Properties of Galactic and Extragalactic Black Hole Candidates

We review current theoretical understanding of the spectral properties (low and high states, transition of states, quasi-periodic oscillations etc.) of the low mass as well as supermassive black hole

Accretion processes on a black hole

The effect of cooling on time dependent behaviour of accretion flows around black holes

We present the results of several numerical simulations of two dimensional axi-symmetric accretion flows around black holes using Smoothed Particle Hydrodynamics (SPH) in the presence of cooling

Spectral Properties of Accretion Disks Around Galactic and Extragalactic Black Holes

We study the spectral properties of a very general class of accretion disks which can be decomposed into three distinct components apart from a shock at $r=r_s$: (1) An optically thick Keplerian disk

Grand Unification of Solutions of Accretion and Winds around Black Holes and Neutron Stars

We provide the complete set of global solutions of viscous transonic flows (VTFs) around black holes and neutron stars. These solutions describe the optically thick and optically thin flows from the

Structured coronae of accretion disks

A model for the fluctuating hard component of intense cosmic X-ray sources (such as Cyg X-1) is developed, based upon the amplification of magnetic fields by convective motions and differential
