Short Timescale Photometric and Polarimetric Behavior of two BL Lacertae Type Objects
S. Covino, M. C. Baglio, L. Foschini +20
Blazars are astrophysical sources whose emission is dominated by non-thermal processes, typically interpreted as synchrotron and inverse Compton emission. Although the general pict…
INTEGRAL observations of the GeV blazar PKS1502+106 and of the hard X-ray bright Seyfert Galaxy Mkn841
E. Pian, P. Ubertini, A. Bazzano +15
Extragalactic nuclear activity is best explored with observations at high energies, where the most extreme flux and spectral variations are expected to occur, witnessing changes in…
The changing look of PKS 2149-306
V. Bianchin, L. Foschini, G. Ghisellini +8
Aims: We study the blazar nature of the high-redshift Flat-Spectrum Radio Quasar PKS 2149-306 (z = 2.345) by investigating its long-term behavior. Methods: We analyzed all publicly…
Infrared to X-ray observations of PKS 2155-304 in a low state
L. Foschini, A. Treves, F. Tavecchio +14
AIMS: Our goal is to understand the nature of blazars and the mechanisms for the generation of high-energy gamma-rays, through the investigation of the prototypical blazar PKS 2155…
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…
REM near-IR and optical multiband observations of PKS2155-304 in 2005
A. Dolcini, F. Farfanelli, S. Ciprini +23
Spectral variability is the main tool for constraining emission models of BL Lac objects. By means of systematic observations of the BL Lac prototype PKS 2155-304 in the infrared-o…
