We present a conceptual design for a new X-ray all sky monitor (ASM). Compared with previous ASMs, its salient features are: (1) it has a focusing capability that increases the signal to background ratio by a factor of 3; (2) it has a broad-band width: 200 eV to 15 keV; (3) it has a large X-ray collection area: ∼ 10 cm; (4) it has a duty cycle of nearly 100%, and (5) it can measure the position...

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

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 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.
