A neutrino (/ nj uː ˈ t r iː n oʊ / new-TREE-noh; denoted by the Greek letter ν) is an elementary particle that interacts via the weak interaction and gravity. [2] [3] The neutrino is so named because it is electrically neutral and because its rest mass is so small that it was long thought to be zero.
The SN 1987A neutrino data, although sparse, confirmed the salient features of the basic supernova model of gravitational collapse and associated neutrino emission. [19] It put strong constraints on neutrino properties such as charge and decay rate. [19] [20] The observation is considered a breakthrough in the field of supernova and neutrino ...
Using an observatory under construction deep beneath the Mediterranean Sea near Sicily, scientists have detected a ghostly subatomic particle called a neutrino boasting record-breaking energy in ...
Neutrino experiments are scientific studies investigating the properties of neutrinos, which are subatomic particles that are very difficult to detect due to their weak interactions with matter. Neutrino experiments are essential for understanding the fundamental properties of matter and the universe's behaviour at the subatomic level.
The SuperNova Early Warning System (SNEWS) is a network of neutrino detectors designed to give early warning to astronomers in the event of a supernova in the Milky Way, our home galaxy, or in a nearby galaxy such as the Large Magellanic Cloud or the Canis Major Dwarf Galaxy. As of March 2021, [1] SNEWS has not issued any supernova alerts.
The Cubic Kilometre Neutrino Telescope, or KM3NeT, is a European research infrastructure located at the bottom of the Mediterranean Sea.It hosts water Cherenkov neutrino telescopes designed to detect and study neutrinos from distant astrophysical sources as well as from our own atmosphere, contributing significantly to both astrophysics and particle physics knowledge.
The IceCube Neutrino Observatory built in 2010 in the south pole is the biggest neutrino detector, consisting of thousands of optical sensors buried 500 meters underneath a cubic kilometer of deep, ultra-transparent ice, detects light emitted by charged particles that are produced when a single neutrino collides with a proton or neutron inside ...
The Sudbury Neutrino Observatory (SNO), a 2,100 m (6,900 ft) underground observatory in Sudbury, Canada, is the other site where neutrino oscillation research was taking place in the late 1990s and early 2000s. The results from experiments at this observatory along with those at Super-Kamiokande are what helped solve the solar neutrino problem.
