Spectral evolution of active galactic nuclei: A unified description of the X-ray and gamma [PDF]
A model for spectral evolution is presented whereby active galactic nuclei (AGN) of the type observed individually emerge from an earlier stage at z approx = 4 in which they are the thermal X-ray sources responsible for most of the cosmic X-ray ...

Study of γ-Ray Emission from a Compact Radio Galaxy with the Fermi Large Area Telescope
The Astrophysical JournalThe radio galaxy PKS 1007+142 is classified as a compact steep-spectrum source (CSS) and belongs to the class of young active galactic nuclei (AGNs). In this paper, we investigate the γ -ray emission from this CSS by conducting a comprehensive analysis ...

Diagnosing the Particle Transport Mechanism in the Pulsar Halo via X-Ray Observations
The Astrophysical JournalPulsar halos (also termed “TeV halos”) are a new class of γ -ray sources in the Galaxy, which manifest as extended γ -ray emission around middle-aged pulsars, as discovered around the Geminga pulsar, the Monogem pulsar, and PSR J0622+3749 by the High ...

Likely Detection of GeV γ-Ray Emission from Pulsar Wind Nebula G32.64+0.53 with Fermi-LAT
The Astrophysical JournalIn this study, we report the likely GeV γ -ray emissions originating from the pulsar PSR J1849-0001's pulsar wind nebula (PWN) G32.64+0.53. Our analysis covers approximately 14.7 yr of data from the Fermi Large Area Telescope Pass 8.
