GravEn: Software for the simulation of gravitational wave detector network response [PDF]

open access: yes, 2006
Physically motivated gravitational wave signals are needed in order to study the behaviour and efficacy of different data analysis methods seeking their detection.

SWIGLAL: Python and Octave interfaces to the LALSuite gravitational-wave data analysis libraries

open access: yesSoftwareX, 2020
The LALSuite data analysis libraries, written in C, implement key routines critical to the successful detection of gravitational waves, such as the template waveforms describing the merger of two black holes or two neutron stars.

The cosmological gravitational wave background from primordial density perturbations [PDF]

open access: yes, 2006
We discuss the gravitational wave background generated by primordial density perturbations evolving during the radiation era. At second-order in a perturbative expansion, density fluctuations produce gravitational waves. We calculate the power spectra of

3D characterization of low optical absorption structures in large crystalline sapphire substrates for gravitational wave detectors

open access: yesScientific Reports, 2021
Very high-quality sapphire substrates are key elements of the cryogenic Japanese gravitational interferometer KAGRA, in which they are used to build the main mirrors, working as the test masses to sense the gravitational waves.

Gravitational wave detector response in terms of spacetime Riemann curvature

open access: yes, 2013
Gravitational wave detectors are typically described as responding to gravitational wave metric perturbations, which are gauge-dependent and --- correspondingly --- unphysical quantities.

Gravitational lens time delays and gravitational waves [PDF]

open access: yesPhysical Review D, 1994
Using Fermat's principle, we analyze the effects of very long wavelength gravitational waves upon the images of a gravitationally lensed quasar. We show that the lens equation in the presence of gravity waves is equivalent to that of a lens with different alignment between source, deflector, and observer in the absence of gravity waves.

Characteristics of the pressure profile in the accelerator on the RF negative ion source at ASIPP

open access: yesNanotechnology and Precision Engineering, 2023
Neutral beam injection (NBI) systems based on negative hydrogen ion sources—rather than the positive ion sources that have typically been used to date—will be used in the future magnetically confined nuclear fusion experiments to heat the plasma.

On The Interaction of Gravitational Waves with Magnetic and Electric Fields

open access: yes, 2010
The existence of large--scale magnetic fields in the universe has led to the observation that if gravitational waves propagating in a cosmological environment encounter even a small magnetic field then electromagnetic radiation is produced. To study this

Nonlinear Interactions Between Gravitational Radiation and Modified Alfven Modes in Astrophysical Dusty Plasmas [PDF]

open access: yes, 2006
We present an investigation of nonlinear interactions between Gravitational Radiation and modified Alfv\'{e}n modes in astrophysical dusty plasmas. Assuming that stationary charged dust grains form neutralizing background in an electron-ion-dust plasma ...
