Probing supermassive black hole binaries with orbital resonances of laser-ranged satellites

open access: yesEuropean 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 ...

Gravitational-wave physics and astronomy in the 2020s and 2030s

open access: yesNature 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 ...

Review of closed drift thruster neutral flow dynamics

open access: yesAIP Advances, 2023
Operation of closed drift thruster (CDT) relies mainly on neutral gas, whose trajectory and distribution in the flow field have a significant influence on performance.

A Broadband Signal Recycling Scheme for Approaching the Quantum Limit from Optical Losses

open access: yesGalaxies, 2021
Quantum noise limits the sensitivity of laser interferometric gravitational-wave detectors. Given the state-of-the-art optics, the optical losses define the lower bound of the best possible quantum-limited detector sensitivity.

Advanced Virgo: a second-generation interferometric gravitational wave detector [PDF]

open access: yes, 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

Gravitational waves [PDF]

open access: yesNuclear Physics B - Proceedings Supplements, 1994
In the last few years there have been a number of significant developments in research towards the detection of gravitational radiation from astronomical objects. The construction of 3 large-scale (3- or 4-km) interferometric detectors has been funded; new high-sensitivity bars are under construction; there is a serious proposal using two ...

Mapping the gravitational wave background [PDF]

open access: yes, 2001
The gravitational wave sky is expected to have isolated bright sources superimposed on a diffuse gravitational wave background. The background radiation has two components: a confusion limited background from unresolved astrophysical sources; and a ...

Evanescent gravitational waves [PDF]

open access: yesPhysical Review D, 2020
We describe the properties of evanescent gravitational waves (EGWs)---wave solutions of Einstein equations which decay exponentially in some direction while propagating in another. Evanescent waves are well-known in acoustics and optics and have recently received much attention due to their extraordinary properties such as their transverse spin and ...
