  • Rajpoot, Subhash; Vacaru, Sergiu I. (Singapur : World Scientific Publishing Co. Pte. Ltd., 2018)
    Let g be a pseudo-Riemanian metric on a manifold V with conventional n+n dimensional splitting, n ≥ 2, for a nonholonomic (non-integrable) distribution N and consider a correspondingly adapted linear metric compatible ...
  • Rajpoot, Subhash; Vacaru, Sergiu I. (Singapur : World Scientific Publishing Co. Pte. Ltd., 2018)
    A brief summary of the anholonomic frame deformation method, AFDM, for generating exact solutions with generic off-diagonal metrics and generalized nonlinear connections in modified gravity theories, MGTs, is presented. ...
  • Aufmuth, Peter; Danzmann, Karsten (Bristol : Institute of Physics Publishing, 2005)
    The existence of gravitational radiation is a prediction of Einstein's general theory of relativity. Gravitational waves are perturbations in the curvature of spacetime caused by accelerated masses. Since the 1960s ...
  • Abbott, B.P.; Abbott, R.; Abbott, T.D.; Acernese, F.; Ackley, K.; et al.; LIGO Scientific Collaboration; Virgo Collaboration (College Park, MD : American Physical Society, 2017)
    We describe the observation of GW170104, a gravitational-wave signal produced by the coalescence of a pair of stellar-mass black holes. The signal was measured on January 4, 2017 at 10 11:58.6 UTC by the twin advanced ...
  • Loriani, Sina; Abend, Sven; Gaaloul, Naceur; Meiners, Christian; Schubert, Christian; Tell, Dorothee; Wodey, Étienne; Ertmer, Wolfgang; Schlippert, Dennis; Rasel, Ernst M. (Washington : American Association for the Advancement of Science (A A A S), 2019)
    The phase of matter waves depends on proper time and is therefore susceptible to special-relativistic (kinematic) and gravitational (redshift) time dilation. Hence, it is conceivable that atom interferometers measure ...
  • Danzmann, Karsten (Trieste : International School for Advanced Studies, 2009)
    Gravitational waves have been predicted by Albert Einstein more than 90 years ago as a consequence of his theory of general relativity. Several km-size gravitational wave detectors have now gone into operation on the ground ...
  • Vacaru, Sergiu I. (Singapur : World Scientific Publishing Co. Pte. Ltd., 2018)
    We outline a geometric method of constructing generic off-diagonal and diagonal cosmological solutions of effective Einstein equations modeling modified gravity theories with two non-Riemannian volume forms and associated ...
  • Alexiou, Maria; Gheorghiu, Tamara; Stavrinos, Panayiotis C.; Vacaru, Olivia; Vacaru, Sergiu I. (Singapur : World Scientific Publishing Co. Pte. Ltd., 2018)
    We review the theory of geometric flows on nonholonomic manifolds and tangent bundles and self-similar configurations resulting in generalized Ricci solitons and Einstein-Finsler equations. There are provided new classes ...
  • Abbott, B.P.; Abbott, R.; Abbott, T.D.; Abernathy, M.R.; Acernese, F.; et al.; LIGO Scientific Collaboration; Virgo Collaboration (College Park, MD : American Physical Society, 2016)
    On September 14, 2015 at 09:50:45 UTC the two detectors of the Laser Interferometer Gravitational-Wave Observatory simultaneously observed a transient gravitational-wave signal. The signal sweeps upwards in frequency from ...
  • Gheorghiu, Tamara; Vacaru, Olivia; Vacaru, Sergiu I. (Singapur : World Scientific Publishing Co. Pte. Ltd., 2018)
    We find general parameterizations for generic off-diagonal spacetime metrics and matter sources in general relativity (GR) and two measure/bi-metric modified gravity theories, MGTs, when the field equations decouple with ...
  • Abbott, B.P.; Abbott, R.; Abbott, T.D.; Abernathy, M.R.; Acernese, F.; et al.; LIGO Scientific Collaboration; Virgo Collaboration (College Park, MD : American Physical Society, 2016)
    On September 14, 2015, the Laser Interferometer Gravitational-Wave Observatory (LIGO) detected a gravitational-wave transient (GW150914); we characterize the properties of the source and its parameters. The data around the ...
