Title: Astrophysical gamma-ray production by inverse Compton interactions of relativistic electrons. II. Constraints on compton emission models for NGC 4151, NP 0532, and PSR 0833--45 from gamma-ray data

Abstract

An inverse Compton origin of the ..gamma..-ray emission of point sources reveals itself by a continuous steepening of the differential ..gamma..-ray spectrum with increasing energy due to higher order effects in the Klein-Nishina cross section. It is shown that the observed breaks in the ..gamma..-ray spectra of the Vela pulsar PSR 0833--45, the Crab pulsar NP 0532, and the Seyfert galaxy NGC 4151 can be explained quite naturally by this effect. The implied constraints on the mean energy of the target photon gases allow us to discuss the place of origin of the observed ..gamma..-rays.
