High-vacuum-compatible high-power Faraday isolators for gravitational-wave interferometers [PDF]

open access: yes, 2012
Faraday isolators play a key role in the operation of large-scale gravitational-wave detectors. Second-generation gravitational-wave interferometers such as the Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO) and Advanced Virgo will ...

Review of closed drift thruster neutral flow dynamics

open access: yesAIP Advances, 2023
Operation of closed drift thruster (CDT) relies mainly on neutral gas, whose trajectory and distribution in the flow field have a significant influence on performance.

A Broadband Signal Recycling Scheme for Approaching the Quantum Limit from Optical Losses

open access: yesGalaxies, 2021
Quantum noise limits the sensitivity of laser interferometric gravitational-wave detectors. Given the state-of-the-art optics, the optical losses define the lower bound of the best possible quantum-limited detector sensitivity.

Lunar Gravitational-wave Antenna

open access: yesThe Astrophysical Journal, 2021
Abstract Monitoring of vibrational eigenmodes of an elastic body excited by gravitational waves was one of the first concepts proposed for the detection of gravitational waves. At laboratory scale, these experiments became known as resonant bar detectors first developed by Joseph Weber in the 1960s.

A First Comparison of SLOPE and Other LIGO Burst Event Trigger Generators [PDF]

open access: yes, 2006
A number of different methods have been proposed to identify unanticipated burst sources of gravitational waves in data arising from LIGO and other gravitational wave detectors.

Gravitational waves from self-ordering scalar fields [PDF]

open access: yes, 2009
Gravitational waves were copiously produced in the early Universe whenever the processes taking place were sufficiently violent. The spectra of several of these gravitational wave backgrounds on subhorizon scales have been extensively studied in the ...

Reflection of electromagnetic waves from mixtures of plane gravitational and scalar waves [PDF]

open access: yes, 2006
We consider colliding wave packets consisting of hybrid mixtures of electromagnetic, gravitational and scalar waves. Irrespective of the scalar field, the electromagnetic wave still reflects from the gravitational wave.

No tension between assembly models of super massive black hole binaries and pulsar observations

open access: yesNature Communications, 2018
Pulsar timing arrays enable the search for the isotropic gravitational-wave (GW) background originating from super massive black hole binary populations, but impose a stringent upper limit on the GW characteristic amplitude.

Pseudoplane-wave gravitational calibrator for gravitational wave observatories

open access: yesPhysical Review D, 2023
The precisions of existing gravitational calibrators for gravitational wave observatories are limited by their dependence on the relative position between the calibrators and the observatory's test masses. Here we present a novel geometry consisting of four quadrupole rotors placed at the vertices of a rectangle centered on the test mass.

An information-theoretic approach to the gravitational-wave burst detection problem [PDF]

open access: yes, 2017
The observational era of gravitational-wave astronomy began in the Fall of 2015 with the detection of GW150914. One potential type of detectable gravitational wave is short-duration gravitational-wave bursts, whose waveforms can be difficult to predict ...
