X-ray properties of AGN from the CJF sample
Listed in IVOA Registry (Virtual Observatory)
We present the soft X-ray properties obtained in the ROSAT All-Sky survey and from pointed PSPC observations for the AGN in the complete flux-density limited Caltech-Jodrell Bank flat spectrum sample (hereafter CJF).
Description
CJF is a VLBI survey (VLBA observations at 5GHz) of 293 AGN with detailed information on jet component motion. We investigate and discuss the soft X-ray properties of this AGN sample and examine the correlations between X-ray and VLBI properties, test beaming scenarios, and search for the discriminating properties between the sub-samples detected and not detected by ROSAT.
Comparing the observed and the predicted X-ray fluxes by assuming an Inverse Compton (IC) origin for the observed X-rays, we compute the beaming or Doppler factor, {delta}_IC_, for the CJF sources and compare it with the equipartition Doppler factor, {delta}_EQ_. We further contrast the Doppler factors with other beaming indicators derived from the VLBI observations, such as the value of the expansion velocity, and the observed and intrinsic brightness temperature.

We calculate two different core dominance parameters (R): the ratio of total VLBI flux to single-dish flux, R_V_, and the ratio of the VLBI core-component flux to single-dish flux, R_C_. In addition, we investigate the large-scale radio structure of the AGN and the difference between the pc- and kpc-scale structure (misalignment) with regard to the X-ray observations.
