Gravitational-wave physics and astronomy in the 2020s and 2030s
Nature Reviews Physics, 2021 The 100 years since the publication of Albert Einstein’s theory of general relativity saw significant development of the understanding of the theory, the identification of potential astrophysical sources of sufficiently strong gravitational waves and ...

Advanced Virgo: a second-generation interferometric gravitational wave detector [PDF]
, 2014 Advanced Virgo is the project to upgrade the Virgo interferometric detector of gravitational waves, with the aim of increasing the number of observable galaxies (and thus the detection rate) by three orders of magnitude. The project is now in an advanced

Searches for continuous-wave gravitational radiation [PDF]
Living 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.

Current status of space gravitational wave antenna DECIGO and B-DECIGO [PDF]
Progress of Theoretical and Experimental Physics, 2020 The Deci-hertz Interferometer Gravitational Wave Observatory (DECIGO) is a future Japanese space mission with a frequency band of 0.1 Hz to 10 Hz. DECIGO aims at the detection of primordial gravitational waves, which could have been produced during the

Twisted gravitational waves [PDF]
Physical Review D, 2018 In general relativity (GR), linearized gravitational waves propagating in empty Minkowski spacetime along a fixed spatial direction have the property that the wave front is the Euclidean plane. Beyond the linear regime, exact plane waves in GR have been studied theoretically for a long time and many exact vacuum solutions of the gravitational field ...

Probing supermassive black hole binaries with orbital resonances of laser-ranged satellites
European Physical Journal C: Particles and Fields, 2023 Coalescing supermassive black hole binaries (SMBHBs) are the primary source candidates for low frequency gravitational wave (GW) detections, which could bring us deep insights into galaxy evolutions over cosmic time and violent processes of spacetime ...
