Spectral Properties of M87 Using Two-Component Flow

TL;DR

This paper models M87's spectral data with a two-component advective disk, attributing the flat spectrum to synchrotron radiation from shock-accelerated non-thermal electrons in the CENBOL region.

Contribution

It introduces a two-component flow model to explain M87's spectral features, emphasizing shock acceleration of electrons as the origin of non-thermal emission.

Findings

Flat spectrum explained by synchrotron radiation from non-thermal electrons

Non-thermal electron distribution results from shock acceleration in sub-Keplerian flow

Model fits observational data of M87 successfully

Abstract

We fit the observational data for M87 using two-component advective disk model. We show that the flat spectrum from the nucleus of M87 is due to synchrotron radiation produced by non-thermal electrons in the CENBOL. The non-thermal distribution is produced due to acceleration of electrons across the shock in a sub-Keplerian flow.
