Gravitational Wave & Relativity Impact Electronic Communication & Engineering

MATEC Web of Conferences, 2017
About a few months ago (Feb 11, 2016), the LIGO (Laser Interferometer Gravitational-Wave Observatory) scientist team researchers made an announcement that they had confirmed the gravitational wave already detected on Sept 14, 2015 (by LIGO’s twin ...

The GEO 600 gravitational wave detector [PDF]

Classical and Quantum Gravity, 2002
The GEO 600 laser interferometer with 600 m armlength is part of a worldwide network of gravitational wave detectors. Due to the use of advanced technologies like multiple pendulum suspensions with a monolithic last stage and signal recycling, the anticipated sensitivity of GEO 600 is close to the initial sensitivity of detectors with several ...

Gravitational-wave signatures of chiral-symmetric technicolor

Physics Letters B, 2022
A chiral-symmetric technicolor model successfully reconciles the tension between electroweak precision tests and traditional technicolor models. Focusing on its simplest realization preserving the conventional Higgs mechanism, we study its primordial ...

Subtracting and Monitoring Tilt-to-length Noise under High Differential Wavefront Sensing Noise Using Convolutional Neural Networks and Time Delay Interferometry

The Astrophysical Journal
Gravitational waves (GWs) provide a powerful tool to probe energetic astrophysical events and test fundamental physics, with space-based detectors enabling access to low-frequency signals from massive black hole mergers, extreme mass-ratio inspirals, and

The Stochastic Gravitational Wave Background from Magnetars

Universe, 2021
Magnetars have already been a potential candidate as gravitational wave sources that could be detected by current and future terrestrial as well as ground-based gravitational wave detectors.

ANGULAR NOISE IN GRAVITATIONAL WAVE DETECTORS [PDF]

The Ninth Marcel Grossmann Meeting, 2002
Angular fluctuations of suspended mirrors in gravitational wave interferometers are a source of noise both for the locking and the operation of the detectors. We describe here some of the sources of these fluctuations and methods for the estimation of their order of magnitude.

Hearing Higgs with gravitational wave detectors [PDF]

Journal of Cosmology and Astroparticle Physics, 2021
AbstractThe relic gravitational wave background due to tensor linear perturbations generated during Higgs inflation is computed. Both the Standard Model and a well-motivated phenomenological completion (that accounts for all the experimentally confirmed evidence of new physics) are considered. We focus on critical Higgs inflation, which improves on the

Physics, Astrophysics and Cosmology with Gravitational Waves

Living Reviews in Relativity, 2009
Gravitational wave detectors are already operating at interesting sensitivity levels, and they have an upgrade path that should result in secure detections by 2014.

A formalism for magnon gravitational wave detectors

European Physical Journal C: Particles and Fields, 2020
In order to detect high frequency gravitational waves, we need a new detection method. In this paper, we develop a formalism for a gravitational wave detector using magnons in a cavity. Using Fermi normal coordinates and taking the non-relativistic limit,

Diffractive Optics for Gravitational Wave Detectors

Journal of Physics: Conference Series, 2006
All-reflective interferometry based on nano-structured diffraction gratings offers new possibilities for gravitational wave detection. We investigate an all-reflective Fabry-Perot interferometer concept in 2nd order Littrow mount. The input-output relations for such a resonator are derived treating the grating coupler by means of a scattering matrix ...
