Properties of accretion shock waves in viscous flows with cooling effects

TL;DR

This paper investigates how shock waves form and behave in viscous accretion flows around black holes, considering cooling effects, and explores their observational implications.

Contribution

It provides a comprehensive analysis of shock properties in viscous, cooling accretion flows, including parameter space and shock oscillation conditions.

Findings

Identified parameter regions for steady and oscillating shocks.

Analyzed the impact of cooling and viscosity on shock formation.

Linked shock behavior to black hole observational features.

Abstract

We study the properties of the shock waves for a viscous accretion flow having low angular momentum in presence of synchrotron cooling. We present all possible accretion solutions in terms of flow parameters. We identify the region of the parameter space for steady and oscillating shocks and show the effect of various energy dissipation processes on it. We discuss the role of the shock waves while explaining the observations from black hole candidates.
