Observations of 54 Active Galactic Nuclei with the HEGRA

M. Tluczykont, G. Heinzelmann

Abstract

In total 54 Active Galactic Nuclei (AGN) apart from Mrk-421 and Mrk501 have been observed between 1996 and 2002 with the HEGRA Cherenkov Telescopes in the TeV energy regime. Among the observed 54 AGN are the meanwhile well established BL Lac type objects H 1426+428 and 1ES 1959+650. The BL Lac object 1ES 2344+514 and the radio galaxy M 87 show evidence for a signal on a 4 σ level. Fluxes resp. upper limits are given for each of the 54 AGN.
