Multiwavelength observations of 26W20, a radio galaxy which displays BL Lacertae characteristics.

Abstract (from CDS):

object{26W20}, a radio galaxy located at a projected distance of 2.2Mpc from the center of Abell 754 (z=0.054) exhibits core emission properties similar to those of a BL Lac object. New radio observations and VLA archival data show parsec scale features in the core (Lr∼1041erg/s) with a flat spectrum. From observations with ROSAT, we demonstrate that the X-ray core emission (Lx=3x1043erg/s) is non-thermal and variable. An 18% increase in the X-ray luminosity was observed in two observations separated by five days. The optical morphology is that of a large, normal elliptical galaxy (mv=15.6) and the optical spectrum lacks strong emission lines. If the innermost segment of the radio jet is close to our line of sight, Doppler boosting could explain both the observed X-ray intensity and the absence of emitting line regions.
