Neutrino astronomy — is the branch of astronomy that observes astronomical objects with neutrino detectors in special observatories. Nuclear reactions in stars and supernova explosions produce very large numbers of neutrinos, a very few of which may be detected by a… … Wikipedia
Neutrino — For other uses, see Neutrino (disambiguation). Neutrino/Antineutrino The first use of a hydrogen bubble chamber to detect neutrinos, on November 13, 1970. A neutrino hit a proton in a hydrogen atom. The collision occurred at the point where three … Wikipedia
Neutrino detector — The Sudbury Neutrino Observatory, a 12 meter sphere filled with heavy water surrounded by light detectors located 2000 meters below the ground in Sudbury, Ontario, Canada. A neutrino detector is a physics apparatus designed to study neutrinos.… … Wikipedia
Neutrino theory of light — The neutrino theory of light is the proposal that the photon is a composite particle formed of a neutrino antineutrino pair. It is based on the idea that emission and absorption of a photon corresponds to the creation and annihilation of a… … Wikipedia

Neutrino decoupling — In Big Bang cosmology, neutrino decoupling refers to the epoch at which neutrinos ceased interacting with baryonic matter, and thereby ceased influencing the dynamics of the universe at early times.[1] Prior to decoupling, neutrinos were in… … Wikipedia
Neutrino telescope — In astronomy, a neutrino telescope is usually a detector consisting of a large mass of water or ice, surrounded by an array of sensitive light detectors known as photomultiplier tubes. This allows the observation of astronomical objects by… … Wikipedia
Radiation Bêta — Radioactivité β La radioactivité bêta ou émission bêta (symbole β) est un type de désintégration radioactive dans laquelle une particule bêta (un électron ou un positron) est émise. On parle de désintégration bêta moins (β ) (basse énergie) ou… … Wikipédia en Français
