A Spaceborne Mounting Method for Fixing a Cubic Fabry–Pérot Cavity in Ultra-Stable Lasers

open access: yesApplied Sciences, 2022
A spaceborne mounting method for fixing a 100 × 100 × 100 mm cubic Fabry–Pérot (FP) cavity is presented. The method constrains the FP cavity in eight directions with a titanium bracket, PEEK gaskets, and vacuum glue.

Challenges and opportunities of gravitational-wave searches at MHz to GHz frequencies [PDF]

open access: yesLiving Reviews in Relativity, 2020
The first direct measurement of gravitational waves by the LIGO and Virgo collaborations has opened up new avenues to explore our Universe. This white paper outlines the challenges and gains expected in gravitational-wave searches at frequencies above ...

Searches for continuous-wave gravitational radiation [PDF]

open access: yesLiving Reviews in Relativity, 2022
Now that detection of gravitational-wave signals from the coalescence of extra-galactic compact binary star mergers has become nearly routine, it is intriguing to consider other potential gravitational-wave signatures.

The Gravitational-wave physics II: Progress [PDF]

open access: yesScience China Physics Mechanics and Astronomy, 2021
It has been a half-decade since the first direct detection of gravitational waves, which signifies the coming of the era of the gravitational-wave astronomy and gravitational-wave cosmology. The increasing number of the detected gravitational-wave events

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.

Search for Lensing Signatures in the Gravitational-Wave Observations from the First Half of LIGO–Virgo’s Third Observing Run [PDF]

open access: yes, 2021
We search for signatures of gravitational lensing in the gravitational-wave signals from compact binary coalescences detected by Advanced Laser Interferometer Gravitational-wave Observatory (LIGO) and Advanced Virgo during O3a, the first half of their ...

Gravitational waves in the nonsymmetric gravitational theory [PDF]

open access: yesPhysics Letters A, 1993
We prove that the flux of gravitational radiation from an isolated source in the Nonsymmetric Gravitational Theory is identical to that found in Einstein's General Theory of Relativity.
