An optical view of BL Lacertae objects
R Falomo, E Pian, A Treves - The Astronomy and Astrophysics Review, 2014 - Springer
BL Lac objects are active nuclei, hosted in massive elliptical galaxies, the emission of which
is dominated by a relativistic jet closely aligned with the line of sight. This implies the …
