The Brera Multi-scale Wavelet ROSAT HRI source catalogue (BMW-HRI)
M. R. Panzera, S. Campana, S. Covino +4
We present the Brera Multi-scale Wavelet ROSAT HRI source catalogue (BMW-HRI) derived from all ROSAT HRI pointed observations with exposure time longer than 100 s available in the…
BL Lacertae: the multiwavelength campaign of 2000
M. Ravasio, G. Tagliaferri, G. Ghisellini +9
We present two BeppoSAX observations of BL Lacertae as part of a multiwavelength radio-to-TeV campaign. During the first observation we observe a faint Compton spectrum, while duri…
BeppoSAX ToO Observations on BLAZARS
Gianpiero Tagliaferri, Gabriele Ghisellini, Marcello Ravasio
We summarize the results of BeppoSAX ToO observation of blazars that were known to be in a high state from observations carried out in the optical or X-ray or TeV bands.In some of…
Broadband Spectra and Variability of BL Lacertae in 2000
M. Boettcher, H. D. Aller, M. F. Aller +6
We have organized an extensive multiwavelength campaign on BL Lacertae in the second half of 2000. Simultaneous or quasi-simultaneous observations were taken at radio frequencies,…
Four Years Monitoring of Blazar PKS 2155-304 with BeppoSAX: Probing the Dynamics of the Jet
Y. H. Zhang, A. Treves, A. Celotti +7
PKS 2155--304 is one of the brightest blazars in the X-ray band. It was repeatedly monitored with BeppoSax during three long campaigns of about 2 days each in November of 1996, 199…
BL Lacertae: complex spectral variability and rapid synchrotron flare detected with BeppoSAX
M. Ravasio, G. Tagliaferri, G. Ghisellini +23
We report on two BeppoSAX observations of BL Lac (2200+420) performed respectively in June and December 1999, as part of a ToO program to monitor blazars in high states of activity…
