The gravitational-wave physics [PDF]
National Science Review, 2017 Abstract The direct detection of gravitational wave by Laser Interferometer Gravitational-Wave Observatory indicates the coming of the era of gravitational-wave astronomy and gravitational-wave cosmology. It is expected that more and more gravitational-wave events will be detected by currently existing and planned gravitational-wave ...

Exploring the CPT violation and birefringence of gravitational waves with ground- and space-based gravitational-wave interferometers [PDF]
European Physical Journal C: Particles and Fields, 2020 In the gravitational sector, we study the CPT violation and birefringence in gravitational waves. In presence of the CPT violation, a relative dephasing is generated between two circular polarization states of gravitational waves. This effect induces the

Observing invisible axions with gravitational waves [PDF]
Journal of Cosmology and Astroparticle Physics, 2021 If the Peccei-Quinn symmetry associated to an axion has ever been restored after inflation, axion strings inevitably produce a contribution to the stochastic gravitational wave background.

New determination of |V ub /V cb | from B s 0 $$ {B}_s^0 $$ → {K − , D s − $$ {D}_s^{-} $$ }μ + ν
Journal of High Energy Physics, 2023 We update the full set of B ¯ $$ \overline{B} $$ s → K form factors using light-cone sum rules with an on-shell kaon. Our approach determines the relevant sum rule parameters — the duality thresholds — from a Bayesian fit for the first time.

Gravitational waves from a universe filled with primordial black holes [PDF]
Journal of Cosmology and Astroparticle Physics, 2020 Ultra-light primordial black holes, with masses m PBH < 109g, evaporate before big-bang nucleosynthesis and can therefore not be directly constrained. They can however be so abundant that they dominate the universe content for a transient period (before ...

High-Accuracy Guide Star Catalogue Generation with a Machine Learning Classification Algorithm
Sensors, 2021 In order to detect gravitational waves and characterise their sources, three laser links were constructed with three identical satellites, such that interferometric measurements for scientific experiments can be carried out.

Observation of Gravitational Waves from Two Neutron Star–Black Hole Coalescences
, 2021 We report the observation of gravitational waves from two compact binary coalescences in LIGO’s and Virgo’s third observing run with properties consistent with neutron star–black hole (NSBH) binaries.

Sensors, 2023 A distributed six-degree-of-freedom (6-DOF) cooperative control for multiple spacecraft formation is investigated considering parametric uncertainties, external disturbances, and time-varying communication delays.

Are there echoes of gravitational waves?
International Journal of Modern Physics D, 2022 In several approaches to evading the information paradox, the semiclassical black hole is replaced by an Exotic Compact Object (ECO). It has been conjectured that gravitational waves emitted by the merger of ECOs can reflect off the ECOs and produce a detectable ‘echo’.
