The polyhedral nature of LINERs: An XMM-Newton view of LINERs in radio galaxies
M. Gliozzi, L. Foschini, R. M. Sambruna +1
Aims: We investigate the origin of X-rays and the nature of accretion flow in 4 LINERs hosted by radio galaxies, namely NGC1692, PKS0625-35, 3C88, 3C444, recently observed with XMM…
On the July 2007 flare of the blazar 3C 454.3
G. Ghisellini, L. Foschini, F. Tavecchio +1
In July 2007, the blazar 3C 454.3 underwent a flare in the optical, reaching R~13 on July 19. Then the optical flux decreased by one magnitude, being R~14 when the source was detec…
First simultaneous multiwavelength observations of the BL Lac object 1ES1959+650 in a steady state with MAGIC and Suzaku/Swift
M. Hayashida, C. Bigongiari, D. Kranich +7
Simultaneous multiwavelength observations were conducted for the BL Lac object 1ES1959+650 in a steady state in May 2006 with the MAGIC telescope and the X-ray satellites Suzaku an…
INTEGRAL and Swift Observations of Blazars in Outburst
Elena Pian, Luigi Foschini, Gabriele Ghisellini
The blazars 3C 454.3, PKS 0537-441 and PKS 2155-304 are traditionally known to be among the most active sources of this class. They emit at all frequencies, up to the gamma-rays, a…
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…
Swift follow-up of the gigantic TeV outburst of PKS 2155-304 in 2006
L. Foschini, G. Ghisellini, F. Tavecchio +12
At the end of July 2006, the blazar PKS 2155-304 (z=0.116) underwent a strong outburst observed at TeV energies by HESS (up to 17 Crab flux level at E > 200 GeV). The Swift satelli…
