  • Attracted very early on by the detection of gravitational waves and by the scale of the scientific and instrumental challenges involved, he called upon other instrumentation specialists (Catherine-Nary Man) and experts in gravitation (Philippe Tourrenc and Jean-Yves Vinet), while his team trained scientists including David Shoemaker and Peter Fritschell, who now play a major role in the LIGO collaboration.

  • When the LIGO instruments detected gravitational waves for the first time on September 14, 2015, we quickly knew that black holes were the source of the signal," says Dr. Frank Ohme, leader of the Max Planck Independent Research Group. (mpg.de)
  • After several years of instrument upgrades, Virgo went in observation mode in August 2017, about one year and half after the two LIGO interferometers in the US had detected for the first time gravitational waves. (uclouvain.be)
  • CP3 members are also actively supporting the Einstein Telescope project, a proposed underground laser interferometer project for gravitational wave detection that is expected to take over from LIGO and Virgo around 2030. (uclouvain.be)
  • It is therefore highly interesting to perform such tests in other environments, such as in strong gravitational fields. (2physics.com)
  • Classical Newtonian mechanics (1687), thermodynamics (1850), and classical electrodynamics (1864) did a wonderful job of describing the everyday world at the close of the 19th century, but early in the 20th century it became apparent that the models upon which these very successful theories were based did not work very well for small things like atoms or for objects moving at high velocities or in strong gravitational fields.

  • Alternative derivations of the time relationship not involving a time-varying gravitational "constant" are obtained by intercomparison of various large numbers. (springer.com)
  • Forces at a distance are explained by fields (gravitational, electric, and magnetic) permeating space that can transfer energy through space. (compadre.org)
  • electric charges or changing magnetic fields cause electric fields. (compadre.org)
  • I would simply enjoin that the electric/magnetic fields, nuclear fields, Casmir fields, light, and gravitation are all manifestations of the one [universal and unified] centropic pressure field. (thunderbolts.info)
  • However, the underlying production mechanism is not understood, except that its efficiency must be greatly enhanced by magnetic fields that redirect some cosmic rays from ingoing to outgoing before they interact. (arxiv.org)
  • In electricity and magnetism the topics are Coulomb's law, electric fields, potential and potential difference, Ohm's law, circuits, resistances in series and parallel, Kirchhoff's laws, magnetic fields and their sources, and forces produced by magnetic fields. (ufv.ca)
  • The electric and magnetic fields in these waves are related by the defined value of the characteristic impedance of vacuum Z 0 . (newworldencyclopedia.org)
  • Klimenko, KG, "Does there arise a significant enhancement of the dynamical quark mass in external magnetic field? (mathnet.ru)
  • Taking into account the coefficients used in accordance with their system of physical units in his writings in 1893 Heaviside gave correct expression for the curl of gravitational quantity, similar in the sense to the magnetic field in electrodynamics. (wikiversity.org)
  • Because it is scattered by the zero-point oscillations of the quantized fields, light of frequency omega travelling normally to two parallel mirrors experiences the vacuum between them as a dispersive medium with refractive index n(omega). (vu.nl)
  • Richard O'Shaughnessy, RIT assistant professor, adds that, 'with Virgo, we can now reliably point to where a gravitational wave signal came from. (scienmag.com)
  • Together with the Italian scientist Adalberto Giazotto, he devoted himself to the design and development of the Virgo gravitational wave detector, now installed at Cascina, near Pisa (Italy). (cnrs.fr)
  • While taking part in designing Virgo, he developed innovative solutions in the field of lasers and optics, while his colleague Adalberto Giazotto worked on suspension systems that enabled mirrors to be decoupled from terrestrial vibrations. (cnrs.fr)
  • The initial fluctuations in the density of the released photons combined with gravitational redshift and Doppler effects get imprinted as fluctuations in the cosmic microwave background with a characteristic amplitude of one part in 100,000. (aip.de)
