Abstract:
We study the γ-ray luminosity and beaming effect for Fermi
blazars. Our results are as follows. (i) There are significant
correlations between γ-ray luminosity and radio core luminosity,
and between γ-ray luminosity and Rv, which suggests that the
γ-ray emissions have a strong beaming effect. (ii) Using the
Lext/Mabs as an indicator of environment effects, we find that there
is no significant correlation between γ-ray luminosity and
Lext/Mabs for all sources when we remove the effect of redshift. Flat
spectrum radio quasars considered alone also do not show a
significant correlation, but BL Lacertae objects (BL Lacs) still show
a significant correlation when we remove the effect of redshift.
These results suggest that the γ-ray emission may be affected by
the environment on a kiloparsec scale for BL Lacs.
Description:
We tried to select a large number of blazars with reliable redshift,
radio core and extended radio luminosity at 1.4GHz. Firstly, we
considered the following samples of blazars to get the radio core
luminosity and extended luminosity at 1.4GHz: Kharb et al. (2010,
J/ApJ/710/764), Antonucci & Ulvestad (1985ApJ...294..158A 1985ApJ...294..158A), Cassaro et
al. (1999A&AS..139..601C 1999A&AS..139..601C), Murphy et al. (1993MNRAS.264..298M 1993MNRAS.264..298M), Landt
& Bignall (2008MNRAS.391..967L 2008MNRAS.391..967L), Caccianiga & Marcha (2004, Cat.
J/MNRAS/348/973), Giroletti et al. (2004).
We cross-correlated these samples with the Fermi LAT Third Source
Catalog (3FGL), and we acquired the 3FGL spectral index and energy
flux at 0.1-100GeV from clean sources in 3FGL (Fermi-LAT Collaboration
2015, J/ApJS/218/23)
Using these catalogs, we compiled 201 Fermi blazars.
