		| Abstract: | 
		Recently, a tight correlation has been discovered between black hole mass and stellar velocity dispersion in galaxy bulges. We are carrying out a program to measure the stellar velocity dispersions in the host galaxies of low-redshift BL Lac objects, so that the black hole masses can be estimated by applying the M-sigma correlation. We will describe our results and the implications for the unification of BL Lac objects and radio galaxies. |
