Extensive near infrared monitoring of millimeter-wave / gamma-ray bright blazars

TL;DR

This study conducted extensive near-infrared monitoring of blazars that are bright in millimeter-wave and gamma-ray frequencies, revealing correlated activity patterns and providing a valuable dataset for understanding their emission mechanisms.

Contribution

It is the first comprehensive near-infrared monitoring campaign of a selected sample of millimeter-wave and gamma-ray bright blazars, with over 2000 data points for correlation analysis.

Findings

Detected correlated near-infrared and gamma-ray activity in blazars.

Provided a large dataset for future multi-wavelength studies.

Identified new sources with activity in both bands.

Abstract

We established a sample of millimeter-wave and gamma-ray bright active galactic nuclei matching the WMAP catalog with the EGRET catalog, highest energy photons and the Fermi bright source list. We have monitored over 80 of these objects in the near infrared, obtaining over 2000 JHKs data points directly comparable with Fermi data. We present examples of correlated near infrared and gamma-ray activity of known blazars and recently identified sources.
