Scientific paper

The Large Area Telescope (LAT) on the Fermi Gamma-ray Space Telescope (formerly GLAST) provides an increase in sensitivity and has detected rapid variability of gamma-ray sources. The variability time scales detected from the gamma-ray loud blazars by LAT and EGRET, and gamma-ray luminosity are used to estimate the central black hole masses. In this work, we find that the lower limits of central black hole masses are in a range of (0.3-24)×107 M &sun;, which are compared with those obtained by other authors. Our results are consistent with other authors’ results. Also, the Lorentz factor, Γ, and the propagation angle, θ, are obtained for 18 blazars for which superluminal motions are known.
