Journal ArticleDOI
Temporal Evolution of Nonthermal Spectra from Supernova Remnants
Steven J. Sturner,Steven J. Sturner,Steven J. Sturner,J. G. Skibo,Charles D. Dermer,J. R. Mattox +5 more
TL;DR: In this paper, the temporally evolving nonthermal particle and photon spectra at different stages in the lifetime of a standard shell-type supernova remnant (SNR) were modeled.
Journal ArticleDOI
Magnetic Compton-induced Pair Cascade Model for Gamma-Ray Pulsars
TL;DR: In this article, an analytic model of magnetic Compton scattering near the polar cap of isolated pulsar magnetospheres was proposed to model the pair cascade induced by relativistic electrons scattering photons through cyclotron resonance.
Journal ArticleDOI

TL;DR: In this paper, three calibration campaigns of the spectrometer SPI have been performed before launch in order to determine the instrument characteristics, such as the effective detection area, the spectral resolution and the angular resolution.
Journal ArticleDOI
Monte Carlo simulations and generation of the SPI response
Steven J. Sturner,Steven J. Sturner,Chris Shrader,Chris Shrader,Georg Weidenspointner,Georg Weidenspointner,Bonnard J. Teegarden,David Attié,Bertrand Cordier,Roland Diehl,C. Ferguson,P. Jean,A. von Kienlin,Ph. Paul,Filomeno Sanchez,Stéphane Schanne,Patrick Sizun,Gerald K. Skinner,Cornelia B. Wunderer +18 more
TL;DR: In this paper, the authors discuss the methods developed for the production of the INTEGRAL/SPI instrument response using a suite of Monte Carlo simulation software based on the GEANT-3 package available from CERN.
Journal ArticleDOI
First identification and modelling of SPI background lines

TL;DR: In this article, the authors used data recorded early in the ESA INTEGRAL observatory to characterize the instrumental background, in particular the many gamma-ray lines produced by cosmic-ray interactions in the instrument and spacecraft materials.
