Can a supernova be located by its neutrinos ?
A future core-collapse supernova in our Galaxy will be detected by several neutrino detectors around the world. The neutrinos escape from the supernova core over several seconds from the time of collapse, unlike the electromagnetic radiation, emitted from the envelope, which is delayed by a time of the order of hours. In addition, the electromagnetic radiation can be obscured by dust in the int...
متن کاملDetermining the Supernova Direction by its Neutrinos
Supernova neutrinos, which arrive at Earth earlier than light, allow for the earliest determination of the direction of the supernova. The topic of this paper is to study how accurately we can determine the supernova direction. We simulate supernova neutrino events at the SuperKamiokande detector, using a realistic supernova model and several realistic neutrino oscillation models. With the resu...
متن کاملSupernova Neutrinos
A nascent neutron star resulting from stellar collapse is a prodigious source of neutrinos of all flavors. While the most basic features of this neutrino emission can be estimated from simple considerations, the detailed simulation of the neutrinos’ decoupling from the hot neutron star is not yet computationally tractable in its full glory, being a time-dependent six-dimensional transport probl...
متن کاملCan sterile neutrinos be the dark matter?
We use the Ly-alpha forest power spectrum measured by the Sloan Digital Sky Survey and high-resolution spectroscopy observations in combination with cosmic microwave background and galaxy clustering constraints to place limits on a sterile neutrino as a dark matter candidate in the warm dark matter scenario. Such a neutrino would be created in the early Universe through mixing with an active ne...
متن کاملCan Neutrinos be Degenerate in Mass?
We reconsider the possibility that the masses of the three light neutrinos of the Standard Model might be almost degenerate and close to the present upper limits from Tritium β decay and cosmology. In such a scenario, the cancellations required by the latest upper limit on neutrinoless double-β decay enforce near-maximal mixing that may be compatible only with the vacuum-oscillation scenario fo...
