چکیده

GRB000615 was detected simultaneously by the BeppoSAX GRBM and WFC 1 with a localization uncertainty of 2 ′ (error circle radius). X-ray emission was detected only in the 0.1–4 keV range during a NFI observation started ≃ 10 hours after the trigger time. The positional and temporal analysis shows the presence of two sources, one of which may be related to the GRB.

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...

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.
