Abstract:
We present simultaneous Planck, Swift, Fermi, and ground-based data
for 105 blazars belonging to three samples with flux limits in the
soft X-ray, hard X-ray, and γ-ray bands, with additional 5GHz
flux-density limits to ensure a good probability of a Planck
detection. We compare our results to those of a companion paper
presenting simultaneous Planck and multi-frequency observations of 104
radio-loud northern active galactic nuclei selected at radio
frequencies. While we confirm several previous results, our unique
data set allows us to demonstrate that the selection method strongly
influences the results, producing biases that cannot be ignored.
Description:
In this paper, we considered three samples of blazars that are
flux-limited in the high-energy part of the electromagnetic spectrum:
soft X-ray (0.1-2.4keV) sources from the ROSAT All-Sky Survey Bright
Source Catalog (1RXS, Voges et al. 1999, Cat. IX/10, hereafter RASS
sample), hard X-ray (15-150keV) sources from the Swift-BAT 54-month
source catalog (Cusumano et al. 2010, Cat. J/A+A/524/A64, hereafter
BAT sample), and γ-ray sources from the Fermi-LAT 3-month bright
AGN source list (Abdo et al. 2009, Cat. J/ApJ/700/597, hereafter
Fermi-LAT sample).
