Stavros Katsanevas
Stavros Katsanevas (1953 – 27 November 2022) was a Greek-French astrophysicist who was director of the European Gravitational Observatory, professor (Exceptional Class) at the Université Paris Cité, former director of the AstroParticle and Cosmology (APC) laboratory and former chairman of the Astroparticle Physics European Consortium (APPEC). In 2000, he received for his work on supersymmetry the Physics Prize from the Academy of Athens. In 2011, he was awarded the Ordre National du Merite.

Ordre National Du Merite
A suite, in Western classical music, is an ordered set of instrumental or orchestral/concert band pieces. It originated in the late 14th century as a pairing of dance tunes; and grew in scope so that by the early 17th century it comprised up to five dances, sometimes with a prelude. The separate movements were often thematically and tonally linked. The term can also be used to refer to similar forms in other musical traditions, such as the Turkish fasıl and the Arab nuubaat. In the Baroque era, the suite was an important musical form, also known as ''Suite de danses'', ''Ordre'' (the term favored by François Couperin), ''Partita'', or ''Ouverture'' (after the theatrical "overture" which often included a series of dances) as with the orchestral suites of Christoph Graupner, Telemann and J.S. Bach. During the 18th century, the suite fell out of favour as a cyclical form, giving way to the symphony, sonata and concerto. It was revived in the later 19th century, but in a differen ...

Gravitational Wave
Gravitational waves are oscillations of the gravitational field that Wave propagation, travel through space at the speed of light; they are generated by the relative motion of gravity, gravitating masses. They were proposed by Oliver Heaviside in 1893 and then later by Henri Poincaré in 1905 as the gravitational equivalent of Electromagnetic radiation, electromagnetic waves. In 1916, Albert Einstein demonstrated that gravitational waves result from his general theory of relativity as ripples in spacetime. Gravitational waves transport energy as gravitational radiation, a form of radiant energy similar to electromagnetic radiation. Newton's law of universal gravitation, part of classical mechanics, does not provide for their existence, instead asserting that gravity has instantaneous effect everywhere. Gravitational waves therefore stand as an important relativistic phenomenon that is absent from Newtonian physics. Gravitational-wave astronomy has the advantage that, unlike elec ...

Virgo Interferometer
The Virgo interferometer is a large-scale scientific instrument near Pisa, Italy, for detecting gravitational waves. The detector is a Michelson interferometer, which can detect the minuscule length variations in its two arms induced by the passage of gravitational waves. The required precision is achieved using many systems to isolate it from the outside world, including keeping its mirrors and instrumentation in an ultra-high vacuum and suspending them using complex systems of Pendulum, pendula. Between its periodic observations, the detector is upgraded to increase its sensitivity. The observation runs are performed in collaboration with other similar detectors, including the two Laser Interferometer Gravitational-Wave Observatories (LIGO) in the United States and the Japanese Kamioka Gravitational Wave Detector (KAGRA), because cooperation between several detectors is crucial for detecting gravitational waves and pinpointing their origin. Virgo was conceived and built whe ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Centre National De La Recherche Scientifique
The French National Centre for Scientific Research (, , CNRS) is the French state research organisation and is the largest fundamental science agency in Europe. In 2016, it employed 31,637 staff, including 11,137 tenured researchers, 13,415 engineers and technical staff, and 7,085 contractual workers. It is headquartered in Paris and has administrative offices in Brussels, Beijing, Tokyo, Singapore, Washington, D.C., Bonn, Moscow, Tunis, Johannesburg, Santiago de Chile, Israel, and New Delhi. Organization The CNRS operates on the basis of research units, which are of two kinds: "proper units" (UPRs) are operated solely by the CNRS, and Joint Research Units (UMRs – ) are run in association with other institutions, such as universities or INSERM. Members of Joint Research Units may be either CNRS researchers or university employees ( ''maîtres de conférences'' or ''professeurs''). Each research unit has a numeric code attached and is typically headed by a university profe ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Astroparticle And Cosmology Laboratory
The Astroparticle and Cosmology (APC) laboratory in Paris gathers researchers (experimentalists, theorists and observers) working in different areas including high-energy astrophysics, cosmology, gravitation, and neutrino physics. The institute was founded in January 2005 and soon moved to new Great Mills campus of Paris Cité University in the Paris Rive Gauche area. The laboratory is a "Mixed Research Unit" in French terminology, funded by Paris Diderot University, the Centre national de la recherche scientifique (represented by three of its Institutes: mainly IN2P3, but also INSU and INP), the Commissariat à l'énergie atomique et aux énergies alternatives, and the Paris Observatory. The first director of the laboratory was Pierre Binétruy (2005-2013).

Université Paris VII Denis Diderot
Paris Diderot University, also known as Paris 7 (), was a French university located in Paris, France. It was one of the inheritors of the historic University of Paris, which was split into 13 universities in 1970. Paris Diderot merged with Paris Descartes University in 2019 to form the University of Paris, which was later renamed Paris Cité University. With two Nobel Prize laureates, two Fields Medal winners and two former French Ministers of Education among its faculty or former faculty, the university was famous for its teaching in science, especially in mathematics. Many fundamental results of the theory of probability were discovered at one of its research centres, the ''Laboratoire de Probabilités et Modèles Aléatoires'' (Laboratory of Probability and Random Models). History Paris Diderot University was one of the heirs of the old University of Paris, which ceased to exist in 1970. Professors from the faculties of Science, of Medicine and of Humanities chose then to cr ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Astroparticle Physics
Astroparticle physics, also called particle astrophysics, is a branch of particle physics that studies elementary particles of astrophysical origin and their relation to astrophysics and cosmology. It is a relatively new field of research emerging at the intersection of particle physics, astronomy, astrophysics, detector physics, relativity, solid state physics, and cosmology. Partly motivated by the discovery of neutrino oscillation, the field has undergone rapid development, both theoretically and experimentally, since the early 2000s. History The field of astroparticle physics is evolved out of optical astronomy. With the growth of detector technology came the more mature astrophysics, which involved multiple physics subtopics, such as mechanics, electrodynamics, thermodynamics, plasma physics, nuclear physics, relativity, and particle physics. Particle physicists found astrophysics necessary due to difficulty in producing particles with comparable energy to those found in ...

Neutrino
A neutrino ( ; denoted by the Greek letter ) is an elementary particle that interacts via the weak interaction and gravity. The neutrino is so named because it is electrically neutral and because its rest mass is so small ('' -ino'') that it was long thought to be zero. The rest mass of the neutrino is much smaller than that of the other known elementary particles (excluding massless particles). The weak force has a very short range, the gravitational interaction is extremely weak due to the very small mass of the neutrino, and neutrinos do not participate in the electromagnetic interaction or the strong interaction. Consequently, neutrinos typically pass through normal matter unimpeded and with no detectable effect. Weak interactions create neutrinos in one of three leptonic flavors: # electron neutrino, # muon neutrino, # tau neutrino, Each flavor is associated with the correspondingly named charged lepton. Although neutrinos were long believed to be mas ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
