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…
Patterns of variability in gamma-ray blazars
L. Foschini
Preliminary results of a systematic study on the simultaneous optical-to-X-rays variability in blazars are presented. Data from Swift observations of four bright gamma-ray blazars…
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…
Simultaneous multiwavelength observations of the blazar 1ES1959+650 at a low TeV flux
G. Tagliaferri, L. Foschini, G. Ghisellini +7
We present the results from a multiwavelength campaign on the TeV blazar 1ES 1959+650, performed in May, 2006. Data from the optical, UV, soft- and hard-X-ray and very high energy…
Low energy cut-offs and hard X-ray spectra in high-z radio-loud quasars: the Suzaku view of RBS315
F. Tavecchio, L. Maraschi, G. Ghisellini +4
We present the results from the Suzaku observation of the powerful radio-loud quasar RBS315 (z=2.69), for which a previous XMM-Newton observation showed an extremely flat X-ray con…
