In this article, a broad perspective of supernovae, their classification and mechanism is given. Later, the astrophysical significance of supernovae is discussed in brief.

In this paper, we use the result in [7] to calculate the non-Gaussianity of the racetrack models in [3, 5]. Our results show that the nonGaussianity in [3] is reasonable, while the non-Gaussianity in [5] is beyond the observational limits.

A handful of new experiments aimed at measuring the asyet-undetected polarization of the cosmic background radiation (CBR) are described, with somewhat more detail given for three experiments with which the authors are associated.

We calculate the total γ-ray line emission at ∼450 keV that accompanies 7 Li and 7 Be production by cosmic-ray interactions, including the delayed line emission at 0.478 MeV from 7 Be radioactive decay. We present a new γ-ray spectroscopic test which has the potential to give direct information on the nature of the interstellar regions into which 7 Be ions propagate and decay. Finally, we evalu...
