Cosmic rays from Galactic pulsars
We calculate energy spectra and mass composition of cosmic rays accelerated by the galactic population of pulsars during their radio and gamma-ray phase. It is assumed that a significant part of the pulsar rotational energy is lost on acceleration of iron nuclei extracted from the surface of the neutron star. The nuclei are accelerated, at first when passing the outer gap of the inner pulsar ma...
متن کاملGamma Rays from Millisecond Pulsars
We estimate the contribution of millisecond pulsars to the diffuse gamma-ray background of the Galaxy, and show that a significant fraction of the Galactic background may originate from them. A small number of the unidentified COS-B point sources may, in fact, be millisecond pulsars. It is argued that several hundred millisecond pulsars may be detectable as point sources by the GRO satellite.
متن کاملTeV neutrinos and gamma rays from pulsars
Recent studies suggest that pulsars could be strong sources of TeV muon neutrinos provided positive ions are accelerated by pulsar polar caps to PeV energies. In such a situation muon neutrinos are produced through the delta resonance in interactions of pulsar accelerated ions with its thermal radiation field. High energy gamma rays also should be produced simultaneously in pulsar environment a...
متن کاملGamma Rays from Rotation-powered Pulsars
The seven known gamma-ray pulsars represent a very small fraction of the more than 1000 presently known radio pulsars, yet they can give us valuable information about pulsar particle acceleration and energetics. Although the theory of acceleration and high-energy emission in pulsars has been studied for over 25 years, the origin of the pulsed gamma rays is a question that remains unanswered. Ch...
متن کاملTeV gamma rays from Galactic objects pulsars pulsar nebulae and supernova remnants
Pulsar nebula supernova remnant and nu cleus of active galaxy are found as TeV gamma ray emit ter and the number of such sources is now approaching All of them so far evidenced are explained by electron progenitor The emission process in the TeV energy region is characterized and controlled by the particle interaction of high energy photons and electrons The radiation by electrons implies a tig...
