Gravitational-wave Observatory
A gravitational-wave detector (used in a gravitational-wave observatory) is any device designed to measure tiny distortions of spacetime called gravitational waves. Since the 1960s, various kinds of gravitational-wave detectors have been built and constantly improved. The present-day generation of laser interferometers has reached the necessary sensitivity to detect gravitational waves from astronomical sources, thus forming the primary tool of gravitational-wave astronomy. The first direct observation of gravitational waves was made in September 2015 by the Advanced LIGO observatories, detecting gravitational waves with wavelengths of a few thousand kilometers from a merging binary of stellar black holes. In June 2023, four pulsar timing array collaborations presented the first strong evidence for a gravitational wave background of wavelengths spanning light years, most likely from many binaries of supermassive black holes. Challenge The direct detection of gravitational wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ESPCI Paris
ESPCI Paris (officially the École supérieure de physique et de chimie industrielles de la ville de Paris, , ''The City of Paris Industrial Physics and Chemistry Higher Educational Institution'') is a grande école founded in 1882 by the city of Paris, France. It educates undergraduate and graduate students in physics, chemistry and biology and conducts high-level research in those fields. It is ranked as the first French ''École d'Ingénieurs'' in the 2017 Shanghai Ranking. ESPCI Paris is a constituent college of Université PSL and a founding member of the ParisTech (Paris Institute of Technology) alliance. Two thirds of the students enter the school following a competitive examination (concours X-ESPCI- ENS) following at least two years of Classes Préparatoires. The other students are recruited by submitting applications. The school itself is also known as Physique-Chimie or simply PC. ESPCI Paris nurtures relationships with many industrial partners such as Schlumberger ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
French National Centre For Scientific Research
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 Unit, Joint Research Units (UMRs – ) are run in association with other institutions, such as List of colleges and universities in France, universities or INSERM. Members of Joint Research Units may be either CNRS researchers or university employees (Academic ranks in France, ''maîtres de conférences'' or ''professeurs''). Each ...

Orsay
Orsay () is a Communes of France, commune in the Essonne Departments of France, department in Île-de-France in northern France. It is located in the southwestern suburbs of Paris, France, from the Kilometre Zero, centre of Paris. A fortified location of the Vallée de Chevreuse, Chevreuse valley since the 8th century and agricultural domain of wealthy and influential people, the development of Orsay is marked by the introduction of a Rail transport, railroad in the second half of the 18th century (today the RER B of which two stations are located in Orsay) and donations which allow the construction of a hospital still active to this day. Orsay is the main home to the Paris-Saclay University. The university significantly shapes Orsay's economy as it employs about 10,000 academic workers. The city's economy is also centered on high technology, with several companies drawn to the area by the Paris-Saclay's research and development infrastructure. Seat of the Orsay campus of Pa ...

John L
"John L" is a song by English rock band Black Midi, released in 2021 as the lead single from their second studio album, ''Cavalcade (Black Midi album), Cavalcade''. The song describes the story of a powerful leader, the titular John L, who is eventually betrayed and killed by his followers. It was released on March 23, with the B-side Despair and a music video directed by Nina McNeely. A 12-inch release for the single was made available for pre-order on the same day and released on April 9. The song is one of few on ''Cavalcade'' to have writing credits for guitarist Matt Kwasniewski-Kelvin, written before his departure from the band but recorded after. Composition and recording "John L" is an Avant-garde music, avant-garde progressive rock song described by ''Guitar World'' as "[featuring] dissonant piano chimes, weaving hypnotic vocals, a cacophony of string sounds, and an edge-of-the-seat dynamic range, spanning from complete silence to raucous, high-energy midsections."

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] |
