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...

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

The last years have been an exciting period for the field of the Cosmic Microwave Background (CMB) research. With recent CMB balloon-borne and ground-based experiments we are entering a new era of ’precision’ cosmology that enables us to use the CMB anisotropy measurements to constrain the cosmological parameters and test new theoretical scenarios.
