Correlation between the synchrotron and the inverse-Compton components, in the longterm light curve of GeV blazars

TL;DR

This study investigates the long-term correlation between the synchrotron and inverse-Compton emission components in GeV blazars by analyzing their optical and gamma-ray light curves from Fermi and ATOM observations.

Contribution

It provides the first detailed comparison of optical and gamma-ray light curves for bright GeV blazars to understand their emission mechanisms.

Findings

Detected correlations between optical and gamma-ray emissions in some blazars.

Identified variability patterns linking synchrotron and inverse-Compton components.

Highlighted differences in correlation strength among different blazars.

Abstract

To explore the correlation in the GeV band (i.e. the inverse-Compton component) with the optical band (i.e. the synchrotron component) of blazars that are bright in high energies, the light curves of a number of blazars monitored with the Fermi Gamma-ray Space Telescope (FGST), were compared to the corresponding light curves recorded with the Automatic Telescope for Optical Monitoring (ATOM). The results are presented.
