3C66B as a TeV radiogalaxy
F. Tavecchio, G. Ghisellini
The MAGIC collaboration reported the detection of a new VHE source, MAGIC J0223+430, located close to the position of the blazar 3C66A, considered a candidate TeV blazar since a lo…
Testing the blazar spectral sequence: X-ray selected blazars
L. Maraschi, L. Foschini, G. Ghisellini +2
We present simultaneous optical and X-ray data from Swift for a sample of FSRQs selected from the EMSS survey. We present also a complete analysis of Swift and INTEGRAL data on 4 b…
Extragalactic jets: a new perspective
G. Ghisellini
The power carried by the jet of blazars is large, compared to the luminosity produced by their accretion disk, and is probably in the form of kinetic energy of a normal electron-pr…
The Epeak-Eiso plane of long Gamma Ray Bursts and selection effects
G. Ghirlanda, L. Nava, G. Ghisellini +2
We study the distribution of long Gamma Ray Bursts in the Ep-Eiso and in the Ep,obs-Fluence planes through an updated sample of 76 bursts, with measured redshift and spectral param…
The Spectral Sequence of Blazars - Status and Perspectives
L. Maraschi, G. Ghisellini, F. Tavecchio +2
The present status of the blazar spectral sequence is discussed, including new findings about blazars selected with different criteria than the original complete radio-samples. Des…
The spectrum of the Broad Line Region and the high-energy emission of powerful blazars
F. Tavecchio, G. Ghisellini
High-energy emission (from the X-ray through the gamma-ray band) of Flat Spectrum Radio Quasars is widely associated with the inverse Compton (IC) scattering of ambient photons, pr…
