Deep Blazar Surveys
Paolo Padovani
I address the need for deep blazar surveys by showing that our current understanding of blazars is based on a relatively small number of intrinsically luminous sources. I then revi…
Surveys and the Blazar Parameter Space
E. S. Perlman, P. Padovani, H. Landt +5
The rareness of blazars, combined with the previous history of relatively shallow, single-band surveys, has dramatically colored our perception of these objects. Despite a quarter-…
The Cosmological Evolution of BL Lacertae Objects
P. Giommi, A. Pellizzoni, M. Perri +1
We review the main results from several radio, X-ray and multi-frequency surveys on the topic of cosmological evolution of BL Lacertae objects. Updated findings on BL Lac evolution…
Looking for High Energy Peaked Blazars
L. Costamante, G. Ghisellini, A. Celotti +10
Blazars can be classified on the basis of their overall Spectral Energy Distribution (SED). BL Lac objects are usually divided in LBL or HBL (Low or High energy peaked BL Lacs), ac…
