The Evolution of Neutrino Astronomy
نویسنده
چکیده
The possibility of observing solar neutrinos began to be discussed seriously following the 1958 experimental discovery by Holmgren and Johnston that the cross section for production of the isotope Be by the fusion reaction He + He → Be+ γ was more than a thousand times larger than was previously believed. This result led Willy Fowler and Al Cameron to suggest that B might be produced in the sun in sufficient quantities by the reaction Be + p → B + γ to produce an observable flux of high-energy neutrinos from B beta-decay.

Evolution of Information and Complexity in an Ever-Expanding Universe
Using the usual definitions of information and entropy in quantum gravity and statistical mechanics and the existing views about the relation between information and complexity, we examine the evolution of complexity in an ever expanding universe.
متن کاملInvited review article: IceCube: an instrument for neutrino astronomy.
Neutrino astronomy beyond the Sun was first imagined in the late 1950s; by the 1970s, it was realized that kilometer-scale neutrino detectors were required. The first such instrument, IceCube, is near completion and taking data. The IceCube project transforms 1 km(3) of deep and ultratransparent Antarctic ice into a particle detector. A total of 5160 optical sensors is embedded into a gigaton o...
متن کاملUltra- and Extremely High Energy Neutrino Astronomy
Scientific motivations for ultraand extremely high energy neutrino astronomy are considered. Sources and expected fluxes of EHE/UHE neutrinos are briefly discussed. Operating and planned experiments on astrophysical neutrino detection are reviewed focusing on deep underwater/ice Cherenkov neutrino telescopes.
متن کاملOrigin and evolution of cosmic accelerators - the unique discovery potential of an UHE neutrino telescope Astronomy
One of the most tantalizing questions in astronomy and astrophysics, namely the origin and the evolution of the cosmic accelerators that produce the highest energy cosmic rays (UHECR), may be best addressed through the observation of ultra high energy (UHE) cosmogenic neutrinos. Neutrinos travel from their source undeflected by magnetic fields and unimpeded by interactions with the cosmic micro...

Geography and astronomy are among the oldest and most widely practiced sciences that have continued to exist in modern times, and have always been associated with medicine. In astronomy, this association extends to astronomical calendars and the prediction of the most and least favorable occasions for the treatment of diseases. In the geographical context, it includes health and human diseases ...
متن کاملMassive stars and high-energy neutrinos
Massive stars have been associated with the production of high-energy neutrinos since the early claims of detection of very high-energy gamma rays from Cygnus X-3 in the 1970s and early 1980s. Although such claims are now discredited, many thoretical models were developed predicting significant neutrino fluxes from binary systems with massive stars. With the discovery of microquasars, new, impr...
