Supemovae and their remnants are the main Galactic nucleosynthesis sites and the privileged sources of Galactic cosmic rays. The youngest of such remnants can be studied through two distinct observational features: 44Ti γ‐ray lines and the hard X

A recent CO survey of the Cepheus Flare region (100°≤1≤141°, 8°≤b≤22°) has allowed a detailed study of the diffuse gamma-ray emission and the gas content of this nearby region. The comparison of the HI and CO observations with the COS-B g

In this paper, a maximum-likelihood analysis is used to compare maps of the H I and (C-12)O interstellar gas in the Cepheus Flare region to COS B gamma-ray data for these clouds. The results imply a value of (2.3 + or - 1.2) x 10 to the 20th mol/sq c

If the gas-to-dust ratio is sufficiently uniform throughout the local interstellar medium, galaxy counts may provide a useful probe of the large scale structure of the interstellar gas. This idea substantiated by gamma-ray observations has led to the
