Active Galactic Nuclei (Agns), Doubling Time Scale, Central Black Hole Mass

Scientific paper

The Large Area Telescope (LAT) on the Fermi Gamma-ray Space Telescope (formerly GLAST) provides an increase of sensitivity and has detected rapid variation in the γ-ray region. In this work, the variation timescales detected from the γ-ray loud blazars by LAT and EGRET are used to estimate the central black hole masses for 14 blazars. The obtained masses are in a range of (2.07 ~ 15.54) × 107 M&sun;, the Doppler factors are in the range of δ = 1.12 ~ 4.63, which are comparable with those obtained by other authors.
