Electromagnetic detector for gravitational waves [PDF]

open access: yesPhysics Letters A, 1978
Abstract We analyze the mode of operation of a two-level parametric electromagnetic detector for gravitational waves which is tunable and potentially more sensitive than the mechanical antennas currently considered.

NEARBY STARS AS GRAVITATIONAL WAVE DETECTORS [PDF]

open access: yesThe Astrophysical Journal, 2015
Sun-like stellar oscillations are excited by turbulent convection and have been discovered in some 500 main sequence and sub-giant stars and in more than 12,000 red giant stars. When such stars are near gravitational wave sources, low-order quadrupole acoustic modes are also excited above the experimental threshold of detectability, and they can be ...

Quantum noise in gravitational-wave interferometers: Overview and recent developments [PDF]

open access: yes, 2003
We present an overview of quantum noise in gravitational wave interferometers. Gravitational wave detectors are extensively modified variants of a Michelson interferometer and the quantum noise couplings are strongly influenced by the interferometer ...

Gravitational Wave Astronomy: Delivering on the Promises [PDF]

open access: yes, 2018
Now that LIGO and Virgo have begun to detect gravitational wave events with regularity, the field of gravitational wave astronomy is beginning to realise its promise.

Gravitational Waves Detectors

open access: yesJournal of Physics: Conference Series, 2020
Abstract The search for direct detection of Gravitational Wave made a huge step forward in the years between 2015-2017. After the first detection signals from the coalescence of binary black hole systems, we had both the great success of the LISA pathfinder mission and the detection of the first event due to a neutron star - neutron star

Gravitational wave detectors

open access: yesNew Journal of Physics, 2005
The existence of gravitational radiation is a prediction of Einstein's general theory of relativity. Gravitational waves are perturbations in the curvature of spacetime caused by accelerated masses. Since the 1960s gravitational wave detectors have been built and constantly improved.

Titania-doped tantala/silica coatings for gravitational-wave detection [PDF]

open access: yes, 2006
Reducing thermal noise from optical coatings is crucial to reaching the required sensitivity in next generation interferometric gravitational-wave detectors.

Probing the gravitational wave background from cosmic strings with the alternative LISA-TAIJI network

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
As one of the detection targets of all gravitational wave detectors today, the stochastic gravitational wave background (SGWB) provides an important means of understanding the evolution of our universe.

Distance measures in gravitational-wave astrophysics and cosmology

open access: yes, 2020
We present quantities which characterize the sensitivity of gravitational-wave observatories to sources at cosmological distances. In particular, we introduce and generalize the horizon, range, response, and reach distances.

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.
