نویسنده
چکیده
TeV or Super TeV neutrinos are expected to originate at the Gamma ray burster ( GRB ) events in the universe. These neutrinos are expected to be produced from the photo-meson interaction of the protons in the GRB environment. In the usual picture, the protons in the GRB fireball undergo Fermi acceleration in the ambient magnetic field of the GRB to very high energy. These protons then interact with the MeV, KeV or meV photons to produce Delta particles those subsequently decay to produce very high energy neutrinos. In this note we focus on the 100 TeV neutrinos produced in a GRB in the fireball model. We try to estimate the production point of these multi TeV neutrinos from the center. The strength of the Magnetic field there. Lastly but importantly modification in the spectrum because of neutrino absorption in the ambient magnetic field. The strength of the ambient magnetic field may change the neutrino spectrum.

The present common view about GRB origin is related to cosmology. There are two evidences in favour of this interpretation. The first is connected with statistics, the second is based on measurements of the redshifts in the GRB optical afterglows. Red shifts in optical afterglows had been observed only in long GRB. Statistical errors, and possibility of galactic origin of short GRB is discussed...

We describe the Neutrino Spectrum and detection for SN II sources. We discuss the effects of neutrino mixing in the SN II. A new analysis of SN1987A is described. We discuss the possible detection of the diffuse relic SN II flux. Finally we discuss a new detection concept, OMNIS, for and and detection and compare with μ 2 other present and future SN detectors.

We review some of the expectations for Primordial Black Hole evaporation and we review the properties of short Gamma Ray Bursts. It is plausible that these GRB come from PBH evaporation. We then show that the angular distribution asymmetry recently observed by us could be due to a concentration of PBH in the Galactic Arms like the Orion arm.

We present a possible Cepheid-like luminosity estimator for the longduration gamma-ray bursts based on the variability of their light curves. We also present a preliminary application of this luminosity estimator to 907 long-duration bursts from the BATSE catalog.
