The HRX-BL Lac sample
Listed in IVOA Registry (Virtual Observatory)
The unification of X-ray and radio selected BL Lacs has been an outstanding problem in the blazar research in the past years.
Description
Recent investigations have shown that the gap between the two classes can be filled with intermediate objects and that apparently all differences can be explained by mutual shifts of the peak frequencies of the synchrotron and inverse Compton component of the emission. We study the consequences of this scheme using a new sample of X-ray selected BL Lac objects comprising 104 objects with z<0.9 and a mean redshift of 0.34. 77 BL Lacs, of which the redshift could be determined for 64 (83%) objects, form a complete sample.
