Summary of all Centaurus A Observations with CGRO COMPTEL
Abstract
During more than 9 years in orbit on board the Compton Gamma-Ray Observatory (CGRO), COMPTEL has observed the nearest active galaxy Centaurus A (Cen A, NGC 5128) during 40 CGRO pointings of various duration. All those selected pointings had Cen A closer than 32 degrees from the center of the wide COMPTEL field-of-view and the total effective observing time was 60 days. This wealth of data enable us to derive spectra with unprecedented significance in the COMPTEL energy band 0.8 - 30 MeV and to correlate those MeV spectra with different x-ray intensity states of Cen A. A summary of all CGRO COMPTEL observations of Centaurus A will be given.
