Multifrequency variability of the blazar AO 0235+164. The WEBT campaign in 2004-2005 and long-term SED analysis
C. M. Raiteri, M. Villata, M. Kadler +3
A huge multiwavelength campaign targeting the blazar AO 0235+164 was organized by the Whole Earth Blazar Telescope (WEBT) in 2003-2005 to study the variability properties of the so…
The WEBT BL Lacertae Campaign 2001 and its extension
M. Villata, C. M. Raiteri
BL Lacertae has been the target of four observing campaigns by the Whole Earth Blazar Telescope (WEBT) collaboration. In this paper we present light curves obtained by the…
Parsec Scale Properties of Markarian 501
M. Giroletti, G. Giovannini, L. Feretti +7
We present the results of a high angular resolution study of the BL Lac object Markarian 501 in the radio band. We consider data taken at 14 different epochs, ranging between 1.6 G…
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…
EGRET upper limits on the high-energy gamma-ray emission of galaxy clusters
O. Reimer, M. Pohl, P. Sreekumar +1
We report EGRET upper limits on the high-energy gamma-ray emission from clusters of galaxies. EGRET observations between 1991 and 2000 were analyzed at positions of 58 individual c…
A High-Energy Study of the Geminga Pulsar
M. S. Jackson, J. P. Halpern, E. V. Gotthelf +1
We present the results of deep X-ray and gamma-ray observations of the Geminga pulsar obtained in the final years of the ASCA and CGRO missions, and an upper limit from RXTE. A pha…
