Abstract:
Active galactic nuclei (AGNs) can be divided into two major classes,
namely radio-loud and radio-quiet AGNs. A small subset of the
radio-loud AGNs is called blazars, which are believed to be unified
with Fanaroff-Riley type I/II (FRI/II) radio galaxies. Following our
previous work (Fan et al., 2011RAA....11.1413F 2011RAA....11.1413F), we present a sample
of 2400 sources with measured radio flux densities of the core and
extended components. The sample contains 250 BL Lacs, 520 quasars, 175
Seyferts, 1178 galaxies, 153 FRI or FRII galaxies and 104 unidentified
sources. We then calculate the radio core-dominance parameters and
spectral indices, and study their relationship. Our analysis shows
that the core-dominance parameters and spectral indices are quite
different for different types of sources. We also confirm that the
correlation between core-dominance parameter and spectral index exists
for a large sample presented in this work.
Description:
We compiled 2400 objects with the relevant data to calculate the
core-dominance parameters.
