Detection, Localization and Characterization of Gravitational Wave Bursts in a Pulsar Timing Array [PDF]

, 2010
Efforts to detect gravitational waves by timing an array of pulsars have focused traditionally on stationary gravitational waves: e.g., stochastic or periodic signals.

REVIEW OF GRAVITATIONAL WAVE DETECTIONS: DYNAMICAL SPACE [PDF]

Physics International, 2014
This is a review of the numerous successful gravitational wave detections and the implications for the nature of space and time. The prevailing space time paradigm in physics was founded on the putative “null” results of the Michelson-Morley (MM) 1887 interferometer experiment to detect light speed anisotropy and which resulted in two different new ...

Automatic amplitude control for phasemeter of spaceborne laser interferometry

AIP Advances, 2023
Laser interferometry of the space gravitational wave antenna needs to demodulate the gravitational wave signal by a phasemeter with high phase readout precision.

Continuous Gravitational Waves from Isolated Galactic Neutron Stars in the Advanced Detector Era [PDF]

, 2012
We consider a simulated population of isolated Galactic neutron stars. The rotational frequency of each neutron star evolves through a combination of electromagnetic and gravitational wave emission.

Relic Gravitational Waves and Their Detection [PDF]

, 2000
The range of expected amplitudes and spectral slopes of relic (squeezed) gravitational waves, predicted by theory and partially supported by observations, is within the reach of sensitive gravity-wave detectors.

Compact Binary Coalescences: Astrophysical Processes and Lessons Learned

Galaxies, 2022
On 11 February 2016, the LIGO and Virgo scientific collaborations announced the first direct detection of gravitational waves, a signal caught by the LIGO interferometers on 14 September 2015, and produced by the coalescence of two stellar-mass black ...

Gravitational wave detection using pulsars: status of the Parkes Pulsar Timing Array project [PDF]

, 2008
The first direct detection of gravitational waves may be made through observations of pulsars. The principal aim of pulsar timing array projects being carried out worldwide is to detect ultra-low frequency gravitational waves (f ~ 10^-9 to 10^-8 Hz ...

Phase transition gravitational waves from pseudo-Nambu-Goldstone dark matter and two Higgs doublets

Journal of High Energy Physics, 2021
We investigate the potential stochastic gravitational waves from first-order electroweak phase transitions in a model with pseudo-Nambu-Goldstone dark matter and two Higgs doublets.
