... blazars, HPV, or OVV. In each case we have given the appropriate references
with sources listed at the end of the table. In our earlier lists we attempted to
restrict the objects to those strictly following the original definition of a BL Lac
object.

The emission lines tend to be seen when the BL Lac object itself is faint,
suggesting that they are always present but are swamped by the continuous
emission when the BL Lac object is bright. Clearly, if a BL Lac object were to be
observed ...

We then compared the jet kinematics with the optical and radio light curves
available for this BL Lac object and point out some striking correlations between
the properties of the radio knots and the features in the light curves. We found a ...

That we can see much further into the heart of a BL Lac object than into a Seyfert
argues that the former is surrounded by much less gas and dust. Such a
conclusion would be compatible with BL Lac objects' being elliptical galaxies and

... are essentially normal spiral galaxies that have a bright nucleus. But the
absence of emission lines is a puzzle that is still not understood. The most widely
accepted model of a BL Lac object is that it is an AGN in which the jet is pointing

Other sources display an outburst behavior, which can be interpreted as a source
crossing a caustic; such an explanation has been postulated for the eruptive BL
Lac object 0846+51 [NO86.1], which is also known to be near a foreground ...
