International Pulsar Timing Array
The International Pulsar Timing Array (IPTA) is a multi-institutional, multi-telescope collaboration comprising the European Pulsar Timing Array (EPTA), the North American Nanohertz Observatory for Gravitational Waves (NANOGrav), the Parkes Pulsar Timing Array (PPTA) in Australia, and thIndian Pulsar Timing Array Project(InPTA). The goal of the IPTA is to detect ultra-low-frequency gravitational waves, such as from mergers of supermassive black holes, using an array of approximately 30 pulsars. This goal is shared by each of the participating institutions, but they have all recognized that their goal will be achieved more quickly by combining their respective efforts and resources. Overview The basic experiment exploits the predictability of the times of arrival (TOAs) of pulses from millisecond pulsars (MSPs) and uses them as a system of galactic clocks. Disturbances in the clocks will be measurable at the Earth. A disturbance from a passing gravitational wave will have a parti ...

Colors Of Noise
In audio engineering, electronics, physics, and many other fields, the color of noise or noise spectrum refers to the power spectrum of a noise signal (a signal produced by a stochastic process). Different colors of noise have significantly different properties. For example, as audio signals they will sound different to human ears, and as images they will have a visibly different texture. Therefore, each application typically requires noise of a specific color. This sense of 'color' for noise signals is similar to the concept of timbre in music (which is also called "tone color"; however, the latter is almost always used for sound, and may consider very detailed features of the spectrum). The practice of naming kinds of noise after colors started with white noise, a signal whose spectrum has equal power within any equal interval of frequencies. That name was given by analogy with white light, which was (incorrectly) assumed to have such a flat power spectrum over the visibl ...

Gravitational Wave Background
The gravitational wave background (also GWB and stochastic background) is a random gravitational-wave signal potentially detectable by gravitational wave detection experiments. Since the background is supposed to be statistically random, it has yet been researched only in terms of such statistical descriptors as the mean, the variance, etc. Sources of a stochastic background Several potential sources for the background are hypothesized across various frequency bands of interest, with each source producing a background with different statistical properties. The sources of the stochastic background can be broadly divided into two categories: cosmological sources, and astrophysical sources. Cosmological sources Cosmological backgrounds may arise from several early universe sources. Some examples of these sources include time-varying scalar (classical) fields in the early universe, "preheating" mechanisms after inflation involving energy transfer from inflaton particles to reg ...

Gravitational Wave International Committee
The Gravitational Wave International Committee (or GWIC) is a panel of gravitational wave detection Laboratory or Observatory directors that promotes cooperation and collaboration between the gravitational wave detector projects and provides direction and advice on the future development of the field. Barry Barish founded the GWIC in 1997 and served as the chair from 1997-2003. Mission The mission of GWIC is to facilitate international collaboration and cooperation in the construction, operation and use of the major gravitational wave detection facilities worldwide: *Promote international cooperation in all phases of construction and scientific exploitation of gravitational-wave detectors; *Coordinate and support long-range planning for new instrument proposals, or proposals for instrument upgrades; *Promote the development of gravitational-wave detection as an astronomical tool, exploiting especially the potential for multi-messenger astrophysics; *Organize regular, world-inclu ...

University Of Orléans
The University of Orléans (french: Université d'Orléans) is a French university, in the Academy of Orléans and Tours. As of July 2015 it is a member of the regional university association Leonardo da Vinci consolidated University. History In 1230, when for a time the doctors of the University of Paris were scattered, a number of the teachers and disciples took refuge in Orléans; when pope Boniface VIII, in 1298, promulgated the sixth book of the Decretals, he appointed the doctors of Bologna and the doctors of Orléans to comment upon it. St. Yves (1253–1303) studied civil law at Orléans, and Pope Clement V also studied there law and letters; by a papal bull published at Lyon, 27 January 1306, he endowed the Orléans institutes with the title and privileges of a university. Twelve later popes granted the new university many privileges. In the 14th century it had as many as five thousand students from France, Germany, Lorraine, Burgundy, Champagne, Picardy, Normand ...
