Key Points

  • To explore the multi-wavelength emission behavior and gamma-ray activity of the radio galaxy SBS 1343+537.
  • Conducted coordinated observations using Fermi-LAT, Swift, and SRT.
  • Collected multi-frequency data across radio, optical, X-ray, and gamma-ray wavelengths.
  • Performed broadband modeling to analyze emission mechanisms.
  • Confirmed a short-lived gamma-ray flare with a power-law spectrum.
  • Observed stable X-ray flux and minor ultraviolet activity.
  • Noted an increase in radio flux density at 20 GHz, indicating potential spectral index inversion.

Abstract

The object with extended wings of emission, and core blazar-like properties. It was recently spatially associated with the , on board the . radio galaxy has a radio jet, and complex morphology. Although its classification is still uncertain, in literature it is indicated as a possible FR-I γ-ray source 4FGL J1346.5+5330, which detected by the LAT FGST In June 2024, the observed enhanced γ-ray activity from and observations. Fermi-LAT The event was followed up by the NGSO SRT Here, we present multi-frequency data (radio, optical, , X-ray, and γ-ray) collected during this observing campaign. UV Our results confirm the detection of a short-lived γ-ray flare, consistent with a power-law spectrum. We report a stable X-ray flux, minor activity in the band, and a flux density increase in the radio unit UV 20 GHz band, which might indicate a mild spectral index inversion. The broadband modelling confirms a typical blazar-like emission in the core of this source, dominated by one-zone and leptonic processes. SED SSC EC
