ST ScI Preprint #1396 . ... We focus on data reduction and analysis, describing the procedures used to model the host galaxy surface brightness radial profiles. ... With the present reclassification of the host galaxy of 1418+546 as an elliptical, there remain no undisputed examples of a disk galaxy hosting a BL Lac nucleus. ... At larger redshifts, only six of 23 BL Lac objects are resolved so the present data do not constrain possible luminosity evolution of the host galaxies. ...

... The sky distribution of the BCGs from the HSS sample is shown in Fig. 6 together with BCGs from the SBS and Case surveys (Izotov et al. [ 1993b ]; Pustilnik et al. ... First, we compare the apparent magnitude distributions of the three samples. ... The similar behaviour of the faint end of the apparent magnitude distributions infers that the Northern BCG sample may have a similar completeness down to this limiting magnitude. ...

... The BM effect causes low-luminosity blazars (particularly BL Lacs) to be missed in surveys because the apparent luminosity of the non-thermal nuclear source does not exceed that of the host galaxy by a large factor. ... Browne (1995). ... In addition to these objects, a large fraction of the newly-identified BL Lacs in our sample (10 of 22; see Table 5) have been so classified only by virtue of our usage of the expanded March? et al.

... Dark matter in normal galaxies . ... I will pay attention to such issues as the constraints on dark matter profile, micro-lensing counts from the galactic bar, rotation and the structure of the bar. One of the central issues of the modeling is the exchange of the angular momentum between the disk and the dark matter. ... Our results indicate that in realistic models the exchange of angular momentum between the bar and the dark matter is much smaller than previously estimated. ...
