The Black Hole Masses and Host Galaxies of BL Lac Objects

Abstract

We have measured the central stellar velocity dispersion in the host galaxies of 11 BL Lac objects with redshifts z <= 0.125. The range of velocity dispersions, 170-370 km/s, is similar to that of nearby radio galaxies. Using the correlation between stellar velocity dispersion and black hole mass defined for nearby galaxies, we derive estimates of the black hole masses in the range 10^7.9 - 10^9.2 solar masses. We do not find any significant difference between the black hole masses in high-frequency-peaked and low-frequency-peaked BL Lac objects. Combining the velocity dispersions with previously measured host galaxy structural parameters, we find that the host galaxies lie on the fundamental plane of elliptical galaxies. This supports the conclusions of imaging studies that the majority of BL Lac hosts are normal giant ellipticals.
