Abstract

Isolated black holes accreting interstellar gas can account for the salient properties of the BL Lac-type objects. The observed frequency spectra in the visible and infrared, the rapid variations in intensity and polarisation, and the absence of discrete features in the optical spectra are all consequences of the adopted black hole accretion model.
