Abstract:
We selected 457 blazars (193 flat spectrum radio quasars, 61
low-synchrotron peaked blazars, 69 intermediate-synchrotron peaked
blazars and 134 high-synchrotron peaked blazars) from the second
Fermi-LAT catalog (2FGL) of γ-ray sources, which have X-ray
observations. We calculated the lower limits for their Doppler
factors, δγ, and compared the lower limits with the
available Doppler factors and the apparent superluminal velocities in
the literature.
Description:
Based on the 2FGL catalog and the Roma BZCAT (see Massaro et al. 2009,
J/A+A/495/691; latest version at http://www.asdc.asi.it/bzcat/), we
compiled the available X-ray data from the literature for 457 Fermi
blazars (193 FSRQs, 61 LBLs, 69 IBLs and 134 HBLs),
