dc.descriptionWe present a radio/optical study of a sample of BL Lac objects at arcsecond and milliarcsecond resolution. The sample consists of 30 nearby (z<0.2) BL Lacs, mostly X-ray selected. These nearby objects are weak in the radio, yet we have successfully observed them with the VLA, VLBA and EVN, revealing interesting morphologies. Most importantly, we find evidence of relativistic boosting even in these low power sources (dominant core, one-sided jets). We present a radio/optical comparison including HST observations which have detected compact optical cores in all objects.
