Precision interferometry in a new shape: higher-order Laguerre-Gauss modes for gravitational wave detection [PDF]

open access: yes, 2012
The sensitivity of the next generation of interferometric gravitational wave detectors will be limited in part by thermal noises of the optics. It has been proposed that using higher-order Laguerre-Gauss (LG) beams in the interferometers can reduce this ...

Measurement of Thermo-Optic Properties of Thin Film Dielectric Coatings [PDF]

open access: yes, 2013
We have carried out an experiment to test the theory of the thermo-optic response of a dielectric stack mirror coating and to measure parameters of interest in calculating thermo-optic noise. Specifically, we measured the coefficient of thermal expansion

The Next Generation Global Gravitational Wave Observatory: The Science Book [PDF]

open access: yes, 2021
The next generation of ground-based gravitational-wave detectors will observe coalescences of black holes and neutron stars throughout the cosmos, thousands of them with exceptional fidelity. The Science Book is the result of a 3-year effort to study the

The First Detection of Gravitational Waves

open access: yesUniverse, 2017
This article deals with the first detection of gravitational waves by the advanced Laser Interferometer Gravitational Wave Observatory (LIGO) detectors on 14 September 2015, where the signal was generated by two stellar mass black holes with masses 36

Adaptive optics methods in gravitational wave interferometric detectors, a perspective [PDF]

open access: yes, 2018
The performance of present and future gravitational wave detectors is limited by fundamental factors, such as thermal noise, seismic or newtonian noise and quantum nature of light.

Probing the gravitational wave background from cosmic strings with the alternative LISA-TAIJI network

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
As one of the detection targets of all gravitational wave detectors today, the stochastic gravitational wave background (SGWB) provides an important means of understanding the evolution of our universe.

Barrow entropy and stochastic gravitational wave background generated from cosmological QCD phase transition

open access: yesPhysics Letters B, 2023
In this work we investigate the stochastic gravitational wave background generated during the first-order cosmological QCD phase transition of the early universe in the framework of the Barrow entropy.

Implementation of an Efficient Bayesian Search for Gravitational-wave Bursts with Memory in Pulsar Timing Array Data

open access: yesThe Astrophysical Journal, 2023
The standard Bayesian technique for searching pulsar timing data for gravitational-wave bursts with memory (BWMs) using Markov Chain Monte Carlo (MCMC) sampling is very computationally expensive to perform. In this paper, we explain the implementation of
