How does the Beaming Effect Beam the TeV Blazars?

The detection of TeV emission in extragalactic galaxies has motivated detailed investigations into the beaming effect in blazars, a defining characteristic of relativistic jets that modulates multiwavelength radiation, though quantitative constraints remain limited. This study systematically analyzes the beaming effect in TeV blazars by disentangling beamed and unbeamed components in high-energy spectra (X-ray, $\gamma$-ray, TeV bands) and estimating Doppler factors across these bands, thereby probing their de-beamed intrinsic luminosities. Utilizing a comprehensive sample of TeV blazars, we apply a two-component model to decompose core-dominated and extended emissions. Doppler factors are derived from core-dominance parameters and jet geometries. Results indicate that low-energy peaked sources (LBLs) sources exhibit the strongest beaming, confirming that high energy core-dominance parameters serve as robust tracers of the beaming effect. Doppler factors peak in the $\gamma$-ray band and display a concave-to-convex evolutionary pattern from radio to TeV energies, suggesting distinct emission regions or viewing angles across bands. The derived Doppler factors enable calculation of de-beamed intrinsic luminosities, providing new insights into the intrinsic properties of blazar jets.
