Blazar jets: the spectra
Gabriele Ghisellini
The radiation observed by blazars is believed to originate from the transformation of bulk kinetic energy of relativistic jets into random energy. A simple way to achieve this is t…
HST observations of FR I radiogalaxies: what do they tell us about the BL Lac - FR I unification scheme?
Marco Chiaberge, Annalisa Celotti, Alessandro Capetti +1
We explore the viability of the unification of BL Lacs and FR I radio galaxies by comparing the core emission of radio galaxies with those of BL Lacs, taking advantage of the newly…
Two BeppoSAX observations of BL Lac
G. Tagliaferri, G. Ghisellini, M. Ravasio +14
We present the results of two ToO BeppoSAX observations of BL Lac. During the first observation we detected both the synchrotron and the Compton components. Fast time variability w…
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…
Does the unification of BL Lac and FR I radio galaxies require jet velocity structures?
Marco Chiaberge, Annalisa Celotti, Alessandro Capetti +1
We explore the viability of the unification of BL Lacs and FR I radio galaxies by comparing the core emission of radio galaxies with those of BL Lacs of similar extended radio powe…
X-ray variability and prediction of TeV emission in the HBL 1ES1101-232
A. Wolter, F. Tavecchio, A. Caccianiga +2
1ES1101-232 is a bright BL Lac of the High frequency peak class. We present here the results of two BeppoSAX observations in which the source has shown a variation of about 30% in…
