A detailed analysis of the high energy gamma-ray emission from the Crab pulsar and nebula.

Grenier, I. A.; Hermsen, W.; Bennett, K. +4 more

The gamma-ray emissions from the Crab pulsar and nebula are analyzed. The data were collected from 1975-1982 in the Galactic anticenter region by COS-B in the energy range 50-3000 MeV. The temporal behavior of the pulsed gamma-ray flux from PSR 0531 + 21 and the unpulsed gamma-ray emissions from the Crab region are examined. It is determined that …

High-energy gamma-ray and hard X-ray observations of CYG X-3.

Strong, A. W.; Hermsen, W.; Pollock, A. M. T. +7 more

High-energy (70 MeV < E < 5 GeV) gamma-ray observations of Cyg X-3 by the ESA satellite COS-B and hard X-ray (14 keV < E < 140 keV) observations by the Leiden-MIT balloon experiment, Leimit, are presented. A comparison with, and a study of earlier results over the 14 decades in energy from 1 keV up to ≡10¹⁷eV indicates that …

Cosmic ray gradients in the outer Galaxy

Wolfendale, A. W.; Mayer, C. J.; Richardson, K. M. +2 more

The release of basic cosmic gamma ray data from the COS B satellite experiment has enabled a more detailed analysis than hitherto of the problem of variations of cosmic ray intensity locally and in the Outer Galaxy. It is found that there is still evidence for a modest cosmic ray gradient, particularly at the highest gamma ray energies where the p…
