Temporal and spectral Gamma-ray properties above 250 GeV of Mkn 421 from CAT observations (1998-2001)
Abstract
The γ-ray emission above 250 GeV from the BL Lac object Markarian 421 has been observed by the CAT Cherenkov Imaging Telescope since December, 1996. In 2000 and 2001, the source showed an activity much higher than during the previous 3 years. Results on the source variability and on its energy spectrum obtained from observations during years 2000 and 2001 are reported.
