Abstract |
Centaurus A (Cen A), at a distance of approximately 3.7 Mpc, is the closest radio-loud AGN and is considered as a prototype FRI radio galaxy. Based on ten months of all-sky survey observations the Fermi-LAT Collaboration has reported the detection of high-energy gamma-ray emission from the giant lobes (up to 3 GeV) and from the core of Cen A galaxy. I will discuss the recent observation of Cen A by Fermi LAT using the data obtained for more than 3 year of observations. The larger data set results in the detection of high energy gamma-ray emission up to 6 GeV from the lobes and up to 50 GeV from the core of Cen A. The spectral energy distribution of the lobes is discussed within the time-dependent leptonic and hadronic scenarios. |
