Simulation of Heterodyne Signal for Science Interferometers of Space-Borne Gravitational Wave Detector and Evaluation of Phase Measurement Noise

Photonics
Interferometric signals in space-borne Gravitational Wave Detectors are measured by digital phasemeters. The phasemeter processes signals generated by multiple interferometers, with its primary function being micro-radian level phase measurements.

Study of gravitational waves from phase transitions in three-component dark matter

European Physical Journal C: Particles and Fields
This paper studies gravitational waves in a dark matter model composed of three types of particles with distinct spins, along with a scalar field $$\phi $$ ϕ that mediates interactions between Standard Model particles and dark matter.

The Impact of Dark Matter on Gravitational Wave Detection by Space-Based Interferometers

Universe
The existence of dark matter is supported by multiple astrophysical observations, yet its particle nature remains unknown. The development of gravitational wave astronomy, especially with future space-based detectors such as LISA, provides new ...

State-space algorithm for detecting the nanohertz gravitational wave background

Monthly Notices of the Royal Astronomical Society
ABSTRACT The stochastic gravitational wave background (SGWB) can be observed in the nanohertz band using a pulsar timing array (PTA). Here, a computationally efficient state-space framework is developed for analysing SGWB data, in which the stochastic gravitational wave strain at Earth is tracked with a non-linear Kalman filter and ...

Dynamical 3-Space: Gravitational Wave Detection and the Shnoll Effect

, 2013
Shnoll has investigated the non-Poisson scatter of rate measurements in various phenomena such as biological and chemical reactions, radioactive decay, photodiode current leakage and germanium semiconductor noise, and attributed the scatter to cosmophysical factors.
