First Low-Latency LIGO+Virgo Search for Binary Inspirals and their Electromagnetic Counterparts [PDF]

open access: yes, 2012
Aims. The detection and measurement of gravitational-waves from coalescing neutron-star binary systems is an important science goal for ground-based gravitational-wave detectors.

No tension between assembly models of super massive black hole binaries and pulsar observations

open access: yesNature Communications, 2018
Pulsar timing arrays enable the search for the isotropic gravitational-wave (GW) background originating from super massive black hole binary populations, but impose a stringent upper limit on the GW characteristic amplitude.

The effect of the gravitational constant variation on the propagation of gravitational waves [PDF]

open access: yes, 2023
Since the first detection of gravitational waves, they have been used to investigate various fundamental problems, including the variation of physical constants. Regarding the gravitational constant, previous works focused on the effect of the gravitational constant variation on the gravitational wave generation.

Gravitational wave radiometry: Mapping a stochastic gravitational wave background [PDF]

open access: yes, 2008
The problem of the detection and mapping of a stochastic gravitational wave background (SGWB), either of cosmological or astrophysical origin, bears a strong semblance to the analysis of CMB anisotropy and polarization.

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 ...

Imprint of primordial gravitational wave with extremely low frequency on gravitational lens system [PDF]

open access: yes, 2022
Primordial gravitational waves with extremely low frequency are expected to origin from inflation in the early Universe. The detection of such kind of gravitational waves is of great significance to verify the inflationary theory and determine the energy scale of inflation.

Reflection of electromagnetic waves from mixtures of plane gravitational and scalar waves [PDF]

open access: yes, 2006
We consider colliding wave packets consisting of hybrid mixtures of electromagnetic, gravitational and scalar waves. Irrespective of the scalar field, the electromagnetic wave still reflects from the gravitational wave.

High-vacuum-compatible high-power Faraday isolators for gravitational-wave interferometers [PDF]

open access: yes, 2012
Faraday isolators play a key role in the operation of large-scale gravitational-wave detectors. Second-generation gravitational-wave interferometers such as the Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO) and Advanced Virgo will ...

Contributions of structural variations to the asymptotic mixed‐mode coupling Factor in red giant stars

open access: yesAstronomische Nachrichten, Volume 343, Issue 9-10, November-December 2022., 2022
Abstract The advent of ultra‐precise photometry space missions enables the possibility of investigating stellar interiors with mixed modes. The structural variations induced by the discontinuity of the chemical composition left behind during the first dredge–up is an important feature in the stellar mid‐layers located between the hydrogen‐burning shell
