Hadronic Gamma Rays from Supernova Remnants
A gas cloud near a supernova remnant (SNR) provides a target for pp-collisions leading to subsequent γ-ray emission through π-decay. The assumption of a power-law ambient spectrum of accelerated particles with index near –2 is usually built into models predicting the spectra of very-high energy (VHE) γ-ray emission from SNRs. However, if the gas cloud is located at some distance from the SNR sh...
متن کاملX-rays from Supernova Remnants
A summary of X-ray observations of supernova remnants is presented including the explosion fragment A of the Vela SNR, Tycho, N132D, RX J08524622, the Crab Nebula and the ’bulls eye’, and SN 1987A, high-lighting the progress made with Chandra and XMMNewton and touching upon the questions which arise from these observations and which might inspire future research.
متن کاملGamma-Rays and Neutrinos from Very Young Supernova Remnants
We consider the result of acceleration of heavy ions in the slot gap potential of a very young pulsar with a hot polar cap. Photodisintegration of the heavy ions in the radiation field of the polar cap and pulsar surface gives rise to a flux of energetic neutrons. Some fraction of these neutrons interact with target nuclei in the supernova shell to produce a prompt neutrino and gamma-ray signal...
متن کاملSearch for TeV Gamma-Rays from Shell-Type Supernova Remnants
If cosmic rays with energies <100 TeV originate in the galaxy and are accelerated in shock waves in shell-type supernova remnants (SNRs), gamma-rays will be produced as the result of proton and electron interactions with the local interstellar medium, and by inverse Compton emission from electrons scattering soft photon fields. We report on observations of two supernova remnants with the Whippl...
متن کاملLeptonic origin of TeV gamma-rays from Supernova Remnants
The lineless power-law emission observed by ASCA from the northeastern rim of the supernova remnant SN1006 has recently been interpreted as synchrotron radiation of electrons with energies around 100 TeV. In this letter we calculate the flux of inverse Compton emission at TeV photon energies that is a natural consequence of the existence of such high energy electrons and the cosmic microwave ba...
