On the TeV gamma-ray and X-ray correlations exhibited in high-energy peaked BL Lacs: Mrk 501 and 1ES 1959+650

TL;DR

This paper investigates the correlation between TeV gamma-ray and X-ray emissions in high-energy peaked BL Lac objects, specifically Mrk 501 and 1ES 1959+650, extending previous analyses from Mrk 421 to understand their spectral energy distributions.

Contribution

It extends the analysis of TeV and X-ray correlations to Mrk 501 and 1ES 1959+650, testing the SSC model's predictions for these sources.

Findings

Confirmed correlation between X-ray and TeV gamma-ray fluxes in the studied BL Lacs.

Provided constraints on magnetic field values based on flux correlation analysis.

Supported the applicability of the SSC model to high-energy peaked BL Lacs.

Abstract

The spectral energy distribution (SED) of blazars is generally understood through the standard one-zone synchrotron self-Compton (SSC) model, where a strong correlation between X-ray and TeV gamma-ray fluxes is expected. Recently, for Mrk 421 the correlation was confirmed and interpreted within the SSC model arguing that a description of the correlation up to large flux values considerably restricts the value of the magnetic field under the assumption of an electron spectral index independent of the flux state. In this work, we extend the analysis done on Mrk 421 for other two high-energy peaked BL Lacs: Mrk 501 and 1ES 1959+650.
