Two-component γ-Ray Emission Spectrum and X-Ray Polarization of the Radio Galaxy Pictor A

Two-component γ-Ray Emission Spectrum and X-Ray Polarization of the Radio Galaxy Pictor A

Pictor A is a γ -ray emitting radio galaxy and has a bright hotspot called the western hotspot (WHS), located ∼4′ away from the nucleus. In this work, we present an analysis of its 16 yr Fermi Large Area Telescope (LAT) data and report the Imaging X-ray Polarimetry Explorer (IXPE) observations for t...
