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…
The HST view of the FR I / FR II dichotomy
Marco Chiaberge, Alessandro Capetti, Annalisa Celotti
In order to explore how the FR I / FR II dichotomy is related to the nuclear properties of radio galaxies, we studied a complete sample of 26 nearby FR II radio galaxies using Hubb…
ISO observational campaign of the BL Lac object PKS 2155-304
E. Bertone, G. Tagliaferri, G. Ghisellini +5
The BL Lacertae object PKS 2155-304 was observed by the Infrared Space Observatory in May and June 1996, during a multiwavelength campaign. These are the first observations in the…
