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 ...

Laser acquisition experimental demonstration for space gravitational wave detection missions
Optics Express, 2021 The laser acquisition-pointing technique is one of the most important techniques for space gravitational wave detection missions, like the Taiji program and the LISA (Laser Interferometer Space Antenna) program. The laser acquisition system suppresses the laser deviation angle to 1 µrad at the receiving aperture.

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.

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 ...
