Abstract:
This paper presents a catalog of 312 X-ray selected BL Lacertae
objects (XBLs), optically identified through the end of 2011. It
contains the names from different surveys, equatorial coordinates,
redshifts, multifrequency flux values, and luminosities for each
source. In addition, the different characteristics of XBLs are
statistically investigated (redshift, radio/optical/X-ray
luminosities, central black hole (BH) mass, synchrotron peak
frequency, broadband spectral indices, optical flux variability).
Their values are collected through an extensive bibliographic and
database search or calculated by us. The redshifts range from 0.031 to
0.702 with a maximum of the distribution at z=0.223. The 1.4GHz
luminosities of XBLs logνLν∼39-42erg/s while optical V and
X-ray 0.1-2.4keV bands show logνLν∼43-46erg/s. The XBL hosts
are elliptical galaxies with effective radii reff=3.26-25.40kpc and
ellipticities, ε=0.04-0.52. Their R-band absolute magnitudes
MR range from -21.11mag to -24.86mag with a mean value of -22.83mag.
The V-R indices of the hosts span from 0.61 to 1.52 and reveal a
fourth-degree polynomial relationship with z that enables us to
evaluate the redshifts of five sources whose V-R indices were
determined from the observations but whose redshifts values are either
not found or not confirmed. The XBL nuclei show a wider range of
7.31mag for MR with the highest luminosity corresponding to
MR=-27.24mag. The masses of central BHs are found in the interval
logMBH=7.39-9.30 solar masses (with distribution maximum at
logMBH/M☉=8.30). The synchrotron peak frequencies are spread
over the range logνpeak=14.56-19.18Hz with a peak of the
distribution at logνpeak=16.60Hz. The broadband radio-to-optical
(αro), optical-to-X-ray (αox), and radio-to-X-ray
(αrx) spectral indices are distributed in the intervals
(0.17,0.59), (0.56,1.48), and (0.41,0.75), respectively. In the
optical energy range, the overall flux variability increases, on
average, towards shorter wavelengths: <Δm≥1.22,1.50, and
1.82mag through the R, V, B bands of Johnson-Cousins system,
respectively. XBLs seem be optically less variable at the intranight
timescales compared to the radio-selected BL Lacs (RBLs).
Description:
We present a catalog of 312 X-ray selected BL Lacerate objects (XBLs)
compiled on the basis of different X-ray surveys and optically
identified through the end of 2011. We also performed a statistical
study of the different characteristics of XBLs. The values are
collected through an extensive bibliographic and database search or
calculated by us.
