Gravitational waves [PDF]

Nuclear Physics B - Proceedings Supplements, 1994
In the last few years there have been a number of significant developments in research towards the detection of gravitational radiation from astronomical objects. The construction of 3 large-scale (3- or 4-km) interferometric detectors has been funded; new high-sensitivity bars are under construction; there is a serious proposal using two ...

Review of closed drift thruster neutral flow dynamics

AIP 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

Galaxies, 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

The 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.

Bilby: A User-friendly Bayesian Inference Library for Gravitational-wave Astronomy [PDF]

Astrophysical Journal Supplement Series, 2018
Bayesian parameter estimation is fast becoming the language of gravitational-wave astronomy. It is the method by which gravitational-wave data is used to infer the sources’ astrophysical properties. We introduce a user-friendly Bayesian inference library

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

Nature 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.

Neutron Star Extreme Matter Observatory: A kilohertz-band gravitational-wave detector in the global network [PDF]

Publications Astronomical Society of Australia, 2020
Gravitational waves from coalescing neutron stars encode information about nuclear matter at extreme densities, inaccessible by laboratory experiments. The late inspiral is influenced by the presence of tides, which depend on the neutron star equation of

Pseudoplane-wave gravitational calibrator for gravitational wave observatories

Physical 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.

Potential of Radio Telescopes as High-Frequency Gravitational Wave Detectors.

Physical Review Letters, 2021
In the presence of magnetic fields, gravitational waves are converted into photons and vice versa. We demonstrate that this conversion leads to a distortion of the cosmic microwave background (CMB), which can serve as a detector for MHz to GHz ...
