Exploring the Transitional Parameter Space of Blazars using Gamma-ray and X-ray Population Diagnostics

Sikandar Akbar, Zahir Shah, Zahoor Malik

Changing-look blazars occupy intermediate gamma-ray and X-ray spaces but lie closer to flat-spectrum radio quasars.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Overall, the results suggest that CLBs form a transitional population between the two main blazar subclasses while retaining characteristics closer to the FSRQ population.

C2weakest assumption

The gamma-ray and X-ray parameters drawn from the 4FGL-DR4 and LSXPS catalogs are assumed to be free of major selection biases and to faithfully represent the intrinsic properties of the three populations being compared.

C3one line summary

Changing-look blazars occupy intermediate regions in gamma-ray and X-ray parameter spaces but lie statistically closer to flat-spectrum radio quasars than to BL Lac objects according to centroids, PCA, UMAP, and random-forest classification.
