Overview

Stacked analysis reveals significant gamma-ray emission from Seyfert galaxies, suggesting complex corona structures.

Key Points

  • Gamma-ray detections showed a significant TS of 30.6, indicating strong emission from the AGN sample.
  • Average gamma-ray luminosity reached (1.5±1.0)×10^40 erg/s in the 1-300 GeV range, marking important findings.
  • Using Fermi-Large Area Telescope observations, a stacking technique was applied to enhance detection accuracy.
  • This discovery supports theoretical expectations of compact corona regions but challenges existing models with the extended corona.
