China’s first step towards probing the expanding universe and the nature of gravity using a space borne gravitational wave antenna

, 2021
In this perspective, we outline that a space borne gravitational wave detector network combining LISA and Taiji can be used to measure the Hubble constant with an uncertainty less than 0.5% in ten years, compared with the network of the ground based ...

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 ...

Swope Supernova Survey 2017a (SSS17a), the optical counterpart to a gravitational wave source [PDF]

Science, 2017
Photons from a gravitational wave event Two neutron stars merging together generate a gravitational wave signal and have also been predicted to emit electromagnetic radiation. When the gravitational wave event GW170817 was detected, astronomers rushed to

3D characterization of low optical absorption structures in large crystalline sapphire substrates for gravitational wave detectors

Scientific Reports, 2021
Very high-quality sapphire substrates are key elements of the cryogenic Japanese gravitational interferometer KAGRA, in which they are used to build the main mirrors, working as the test masses to sense the gravitational waves.

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

, 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 ...

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

Gravitational wave detector response in terms of spacetime Riemann curvature

, 2013
Gravitational wave detectors are typically described as responding to gravitational wave metric perturbations, which are gauge-dependent and --- correspondingly --- unphysical quantities.
