A Euro-Asian network of four gravitational-wave (GW) interferometers is considered, taking into account the plan to create such a detector in Novosibirsk. The efficiency assessed by typical numerical criteria, which also depend on characteristics received signal. In this work, we calculate optimal orientation Novosibirsk for problem detecting GW radiation accompanying collapse progenitor star w...

The prospects for the observation of electromagnetic emissions by gravitational wave sources first detected using a network of interferometers are discussed. Various emission mechanisms and detection techniques for compact binary inspirals are studied to show that the pointing ability of gravitational wave observatories and the efficacy of electromagnetic detectors can be combined to predict th...

A search for periodic gravitational-wave signals from isolated neutron stars in the NAUTILUS detector data is presented. We have analyzed half a year of data over the frequency band 〈922.2; 923.2〉Hz, the spindown range 〈−1.463 × 10; 0〉Hz/s and over the entire sky. We have divided the data into 2 day stretches and we have analyzed each stretch coherently using matched filtering. We have imposed ...

The gravitational wave detectors currently in operation perform the analysis of their scientific data jointly. Concerning the search for bursting sources, coherent data analysis methods have been shown to be more efficient. In the coherent approach, the data collected by the detectors are time-shifted and linearly combined so that the signatures received by each detector add up constructively (...

AEGIS (Antimatter Experiment, Gravity, Interferometry and Spectroscopy) is an experiment under development at CERN which will measure earth’s gravitational force on antimatter. This will be done by creating a horizontal pulsed beam of low energy antihydrogen, an atom consisting of an antiproton and a positron. The experiment will measure the vertical deflection of the beam through which it is p...

We present a review of modern optical techniques being used and developed for the field of gravitational wave detection. We describe the current state-of-the-art of gravitational waves detector technologies with regard to optical layouts, suspensions and test masses. We discuss the dominant sources and noise in each of these subsystems and the developments that will help mitigate them for futur...

Similarly to a Yang–Mills propagating field, which must be nonlinear if it is to transport its own charge, only a nonlinear gravitational wave is able to transport energy and momentum. The second order solution describing such physical waves is obtained. The effects they produce on free particles consist of nonlinear oscillations along the direction of propagation. This is the signature a detec...

Motivated by a recently invented scheme of displacement-noise-free gravitational-wave detection, we demonstrate the existence of gravitational-wave detection schemes insusceptible to both displacement and timing (laser) noises and are thus realizable by shot-noise-limited laser interferometry. This is possible due to two reasons: first, gravitational waves and displacement disturbances contribu...

Spin-2, spin-1 and spin-0 modes in linearised teleparallelism are obtained where the totally skew-symmetric complex contortion tensor generates scalar torsion waves and the symmetric contortion in the last two indices generates gravitational waves as gravitational perturbations of flat spacetime with contortion tensor. A gedanken experiment with this gravitational-torsion wave hitting a ring of...

A laser interferometric detector of gravitational waves is studied and a complete solution (to first order in the metric perturbation) of the coupled Einstein-Maxwell equations with appropriate boundary conditions for the light beams is determined. The phase shift, the light deflection and the rotation of the polarization axis induced by gravitational waves are computed. The results are compare...
