Scientific paper

The paper considers long term monitoring by Ariel V of the X-ray source associated with the nucleus of the Seyfert Galaxy NGC4151 which revealed frequent flaring on a time-scale of days. The possibility that all the X-ray emission is contained in flare-like events is discussed within the framework of a shot noise model. This behavior is interpreted in the light of information obtained at other wavelengths, and arguments are advanced to suggest that all emission from 1 keV to 3 MeV arises from the same region of radius of about 10 to the 14th cm. It is also suggested that accretion onto a massive collapsed object is required to explain the efficiency of energy production.
