The gamma-ray photon spectral index view of transition blazars

Abstract The Fermi Large Area Telescope (LAT) has detected a large number of γ-ray-emitting sources, among which jet-dominated active galactic nuclei (AGN) are typically classified as BL Lac objects or flat-spectrum radio quasars based on their spectral properties. However, recent observations have revealed a growing number of jet-dominated AGNs exhibiting transition behaviors between these two subclasses, making their classification less straightforward. In this study, we investigate transition
