Abstract
Centaurus A is the nearest radio-loud AGN and is detected from radioto very high energy gamma-rays. Its nuclear spectral energydistribution shows two peaks, one in the far-infrared band and anotherat about 170 keV. Although, the flux from this nuclear region iswell explained by leptonic models, it fails to account for highenergy tail region above few GeV. We show that, within the jet, thecollision of Fermi accelerated high energy protons with the IC photonsaround the second peak region can produce multi-GeV to TeV gamma-raysand GeV neutrinos through delta-resonance which can explainsimultaneously, the observed GeV-TeV tail in the photon flux and theobserved cosmic ray events by Pierre Auger Observatory. We also estimatethe GeV neutrino flux from it.
