ABSTRACT
Since the time coverage of BATSE is nearly complete over 8 years, this instrument offers a unique opportunity to monitor highly variable sources such as blazars in a relatively unexplored energy band (20–100 keV). Here we present some examples of this capability which is particularly useful during period of flaring activity. Four years of monitoring of the QSO 71.07 in the hard X-ray band is presented which indicates enhanced hard X-ray emission during an optical flare. BATSE also allowed the extraction of spectra during bright states. These data indicate that the spectrum steepens when the source is brighter. Results are also presented for the BL Lacs MKN501 and PKS 2005-489 during high energy flares, first detected by other instruments. The potential of using BATSE to study sources over long periods of time and to follow the emission before and after flares is clearly demonstrated. © 2000 American Institute of Physics.

    We investigate the contribution of blazars to the cosmic X-ray background (CXB). The radio blazar luminosity function is found by beaming the luminosity function of radio loud active galactic nuclei (AGN). Average blazar spectral energy distributions are created to convert radio luminosity to...

    The study of the TeV emission from extragalactic sources is hindered by the uncertainties on the diffuse Extragalactic Background Light (EBL). The recent H.E.S.S. results on the blazars 1ES 1101-232 and H 2356-309 represent a breakthrough on this issue. Their unexpectedly hard spectra allow an...

    Aims. Very high energy (VHE) gamma-ray emission from a distant source (z >≳ 0.2) can be efficiently absorbed by means of the electron-positron pair creation process. Analyses of the unabsorbed spectra imply that the intrinsic TeV emission of some blazars is hard, with spectral indices of...

    The BL Lac object S5 0716+714 was monitored in the optical band during October 2008, December 2008 and February 2009. We achieved a best temporal resolution of about 5 min in the BVRI bands. The source was active during the whole monitoring campaign. It showed microvariability in 13 days out of...

    Many quasi-simultaneous optical observations of nine BL Lac objects are obtained from literature. We study the relationship between the optical spectral index and the luminosity of BL Lac objects, and are tempted to exploit spectral evolution in the optical frequency ranges. Our results show...

    Because of the short duty-cycles and observation-time constraints, studies of bright TeV (E>100 GeV) blazars are mostly restricted to flaring episodes or rather short (days to few weeks) multiwavelength campaigns. At the same time, long-term studies of these objects are essential to gain a more...
