X-Ray Analysis and Modeling of the Broadband Spectrum for the Flaring Radio Galaxy IC 310

POSTER

Abstract

Radio galaxies are active galactic nuclei with jets misaligned with respect to the line of sight, making them a good laboratory for studying jet structure. Only a handful of radio galaxies have been detected at TeV gamma-ray energies. IC 310, a radio galaxy in the Perseus cluster known to exhibit fast TeV gamma-ray variability, was detected at an elevated TeV gamma-ray flux in March 2024 by the LHAASO gamma-ray observatory. Multi-wavelength follow-up observations of IC 310 during the flaring state were organized. We analyzed the X-Ray follow-up observations from the NuSTAR and Swift-XRT telescopes and constructed a broadband spectral energy distribution (SED) using contemporaneous optical and gamma-ray data for IC 310. We also fit the SED with one-zone and two-zone synchrotron self-Compton (SSC) models in order to gain insight to the underlying physics in extreme environments in the universe.
