Gravitational Waves from Gravitational Collapse [PDF]

open access: yesLiving Reviews in Relativity, 2003
Gravitational wave emission from the gravitational collapse of massive stars has been studied for more than three decades. Current state-of-the-art numerical investigations of collapse include those that use progenitors with more realistic angular ...

Gravitational Lensing of Continuous Gravitational Waves [PDF]

open access: yesUniverse, 2021
Continuous gravitational waves are analogous to monochromatic light and could therefore be used to detect wave effects such as interference or diffraction. This would be possible with strongly lensed gravitational waves. This article reviews and summarises the theory of gravitational lensing in the context of gravitational waves in two different ...

Precise Orbit Determination and Accuracy Analysis for BDS-3 Satellites Using SLR Observations

open access: yesRemote Sensing, 2023
Satellite laser ranging (SLR) is the space geodetic technique with the highest degree of range, measuring precision and distances right down to the millimeter level.

Storage Rings and Gravitational Waves: Summary and Outlook [PDF]

open access: yes, 2021
We report some highlights from the ARIES APEC workshop on ``Storage Rings and Gravitational Waves'' (SRGW2021), held in virtual space from 2 February to 18 March 2021, and sketch a tentative landscape for using accelerators and associated technologies

Gravitational Fields and Gravitational Waves [PDF]

open access: yesPhysics Essays, 2021
Abstract For any object with finite velocity, the relative velocity between them will affect the effect between them. This effect can be called the chasing effect (general Doppler effect). LIGO discovered gravitational waves and measured the speed of gravitational waves equal to the speed of light c. Gravitational waves are generated due to the

New determination of |V ub /V cb | from B s 0 $$ {B}_s^0 $$ → {K − , D s − $$ {D}_s^{-} $$ }μ + ν

open access: yesJournal 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.

High-Accuracy Guide Star Catalogue Generation with a Machine Learning Classification Algorithm

open access: yesSensors, 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.

GRAVITATIONAL WAVES IN THE HYPERSPACE? [PDF]

open access: yesModern Physics Letters A, 2009
In the framework of the debate on high-frequency gravitational waves (GWs), after a review of GWs in standard General Relativity, which is due for completness, the possibility of merging such a traditional analysis with the hyperspace formalism that has been recently introduced in some papers in the literature, with the goal of a better understanding ...

Adaptive Control for Gravitational Wave Detection Formation Considering Time-Varying Communication Delays

open access: yesSensors, 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.
