The jet apparent motion and central engine study of Fermi blazars [HEAP]

http://arxiv.org/abs/2303.16383


The study of blazar jet has been performed for several decades via the VLBI technique, while its generation and propagation stay unclear. In the present work, we compiled a sample of 407 VLBI detected \textit{Fermi} blazars (VFBs) and studied the correlations between apparent velocity (${\rm log}\,\beta_{\rm app}$) and jet/accretion disk properties. We found a positive correlation between $\gamma$-ray luminosity (${\rm log}\,L_{\rm \gamma}$) and ${\rm log}\,\beta_{\rm app}$, the correlation suggests that the apparent motion of jet knot is related to the jet power.
