Study of microwave/gamma-ray properties for Fermi-LAT bright AGNs

TL;DR

This study explores the relationship between microwave and gamma-ray emissions in bright AGNs detected by Fermi-LAT, leveraging recent microwave data to understand their emission mechanisms across large cosmological volumes.

Contribution

It provides a systematic analysis of the correlation between microwave and gamma-ray emissions in Fermi-LAT bright AGNs using WMAP data, a novel approach in this context.

Findings

Detected 106 bright, high-latitude AGNs with Fermi-LAT.

Analyzed correlations between microwave and gamma-ray emissions.

Identified potential links between emission mechanisms.

Abstract

Blazars are a small fraction of all extragalactic sources but, unlike other objects, they are strong emitters across the entire electromagnetic spectrum. Recent data in the microwave region of the electromagnetic spectrum have become available to allow for systematic studies of blazars over large cosmological volumes. This frequency band is indeed particularly suited for the selection of blazars since at these frequencies the contamination from radio extended components with steep spectra is no longer present and the emission from the accretion process is negligible. During the first 3 months of scientific operations Fermi-LAT detected 106 bright, high-galactic latitude (| b |> 10 deg) AGNs with high significance. In this study we investigate the possible relations between the microwave and the gamma-ray emissions for Fermi-LAT detected AGNs belonging to WMAP 5th year bright source catalog.
