Auger, Pierre Victor

 

Born May 14, 1899, in Paris. French physicist.

Auger studied at the Ecole Normale Supérieure and the University of Paris. From 1927 to 1969 he worked at the University of Paris, where he became a professor in 1937. In the period from 1941 to 1945 he worked in the USA, Canada, and Great Britain. Auger investigated the photoelectric effect induced by X rays in gases and experimentally confirmed the quantum-mechanical theory of the photoelectric effect. In 1925 he discovered an effect that deals with the ionization of an atom in an excited state; this effect is called the Auger effect and the electrons that are emitted from the atom in the process are called Auger electrons. In 1938, Auger and his colleagues detected extensive atmospheric showers in cosmic rays, called Auger showers.

Auger has been director of the Atomic Energy Commission (1945–48), director of higher education for France (1945–48), assistant director-general of the UNESCO Department of Natural Sciences (1948–59), president of the French Space Commission (1961–62), and director-general of the European Space Research Organization (1962–67).

The discovery reported in the journal Science follows 12 years of data collection by the Pierre Auger Observatory in Argentina.
"There have been other pieces of evidence, but I would say this paper really confirms that most of the highest energy cosmic ray particles are not coming from the Milky Way galaxy," Gregory Snow, a University of Nebraska-Lincoln (UNL) physics professor, who was a co-author on the paper and is education and outreach coordinator for the Pierre Auger Observatory project, said in (http://news.unl.edu/newsrooms/today/article/study-confirms-cosmic-rays-have-extragalactic-origins/) a statement Thursday.
For instance, the Pierre Auger observatory in Argentina used their surface detectors to look for the electromagnetic signature of extensive air showers initiated by the decay of [tau] charged leptons of EeV energies that develop close to the detector [15-17], without finding candidate signals so far.
With upgrades to our detector and techniques we will be able to improve our sample size by an order of magnitude, resolve more mass components, and identify the origin of high-energy cosmic rays and neutrinos.The technique may be scaled up to higher energies, measured at the Pierre Auger Observatory, where mass information is needed to correlate cosmic rays with their astrophysical sources and to confirm the nature of the cutoff at We can even search for particles beyond the GZK limit.
Currently, the Pierre Auger Observatory holds the title of largest array, consisting of 1,600 tanks each containing 12,000 liters of water--a battalion spread out over 3,000 square kilometers.
Ice Cube Neutrino Observatory at the outh Pole is trying to capture neutrinos, while the Pierre Auger Cosmic Ray Observatory in rgentina captures cosmic rays from these objects.
Some examples of specific topics include the importance of astronomical plat archives as complementary support for astroparticle physics, dark energy models toward observational tests and data, high-energy gamma-rays from massive binary systems, anisotropy of ultra-high-energy cosmic rays from the surface array data of the Pierre Auger Observatory, jet collimation by magneto-torsional oscillations, the physics of the interaction of astrophysical jets with the interstellar and intracluster medium, galactic versus extragalactic sources for cosmic rays, neutrino astronomy with the IceCube Observatory and implications for astroparticle physics, and probing gravity in the Earth-Moon system.
Scientists from many countries gathered at the foothills of the Argentine Andes last November to mark the completion of the Pierre Auger (oh-ZHAY) cosmic-ray observatory.
The Pierre Auger Collaboration said the observatory--a sprawling array of remotely monitored water tanks that will detect the rays--will be built In Baca, Bent and Prowers counties, about 180 miles southeast of Denver.
Nearly 60 years ago, the French physicist Pierre Auger discovered that atoms brought to an excited state can undergo a transition to a lower energy state by emitting a bound electron.
In the reciprocal direction, the Pierre Auger Observatory for High Energy Cosmic Rays, recently established in Argentina, receives a large European participation.
