Wide band X-ray and optical observations of the BL Lac object 1ES 1959+650 in high state
G. Tagliaferri, M. Ravasio, G. Ghisellini +5
The blazar 1ES 1959+650 was observed twice by BeppoSAX in September 2001 simultaneously with optical observations. We report here the X-ray data together with the optical, R_C magn…
Coordinated Multiwavelength Observations of BL Lacertae in 2000
M. Boettcher
BL Lacertae was the target of an extensive multiwavelength monitoring campaign in the second half of 2000. Simultaneous or quasi-simultaneous observations were taken at radio (UMRA…
A numerical code to study the variability of Blazar emission
Andrea Tramacere, Gino Tosti
We present a numerical code, written in C, which can be used to simulate or to analyze the emission of Blazars over the entire electromagnetic spectrum. Our code can reproduce the…
Discovery, identification, and study of variability in gamma-ray point sources
M. Fiorucci, N. Marchili, G. Tosti +3
We present preliminary results of a statistical analysis obtained with a sample of blazars observed at the Perugia Astronomical Observatory since 1992. We briefly show how these st…
Optical and radio behaviour of the BL Lacertae object 0716+714
C. M. Raiteri, M. Villata, G. Tosti +24
Eight optical and four radio observatories have been intensively monitoring the BL Lac object 0716+714 in the last years: 4854 data points have been collected in the UBVRI bands si…
Optical variability of the BL Lacertae object GC 0109+224. Multiband behaviour and time scales from a 7-years monitoring campaign
S. Ciprini, G. Tosti, C. M. Raiteri +4
We present the most continuous data base of optical observations ever published on the BL Lacertae object GC 0109+224, collected mainly by the robotic telescope of t…
The BL Lac objects OQ 530 and S5 0716+714. Simultaneous observations in the X-rays, radio, optical and TeV bands
G. Tagliaferri, M. Ravasio, G. Ghisellini +10
We present the results of the BeppoSAX observations of two BL Lacs, OQ 530 and S5 0716+714, as part of a ToO program for the simultaneous observation at radio, optical, X-ray and T…
