Review: the landscape of gravitational wave astronomy

Acta Polytechnica
The direct detection of gravitational waves from a binary black hole merger has opened a new window in observational astronomy. The first three observing runs of the LIGO/Virgo groundbased interferometers have produced a broad range of scientific results,

Testing general relativity with gravitational-wave catalogs: The insidious nature of waveform systematics

iScience, 2021
Summary: Gravitational-wave observations of binary black holes allow new tests of general relativity (GR) to be performed on strong, dynamical gravitational fields.

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

Galaxies, 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.

Squeezing for cosmic symphony

AAPPS Bulletin, 2023
We briefly review the status of applying quantum squeezing to aid the search for gravitational waves with km-scale laser interferometers operating in the audio frequency band.

Gravitational Wave Astronomy with the SKA [PDF]

Proceedings of Advancing Astrophysics with the Square Kilometre Array — PoS(AASKA14), 2015
On a time scale of years to decades, gravitational wave (GW) astronomy will become a reality. Low frequency (nanoHz) GWs are detectable through long-term timing observations of the most stable pulsars. Radio observatories worldwide are currently carrying out observing programmes to detect GWs, with data sets being shared through the International ...

Quantum metrology for gravitational wave astronomy [PDF]

Nature Communications, 2010
Einstein's general theory of relativity predicts that accelerating mass distributions produce gravitational radiation, analogous to electromagnetic radiation from accelerating charges. These gravitational waves (GWs) have not been directly detected to date, but are expected to open a new window to the Universe once the detectors, kilometre-scale laser ...

Introduction to Gravitational Wave Astronomy [PDF]

, 2021
This chapter provides an overview of gravitational wave (GW) astronomy, providing background material that underpins the other, more specialized chapters in this handbook. It starts with a brief historical review of the development of GW astronomy, from Einstein's prediction of GWs in 1916 to the first direct detection in 2015.

Present and Future of Gravitational Wave Astronomy [PDF]

, 2022
The first detection on Earth of a gravitational wave signal from the coalescence of a binary black hole system in 2015 established a new era in astronomy, allowing the scientific community to observe the Universe with a new form of radiation for the ...

Gravitational-wave asteroseismology with fundamental modes from compact binary inspirals

Nature Communications, 2020
Independently measuring the tidal deformability and the fundamental oscillation mode (fmode) frequency enables tests of gravity and the nature of compact binaries.

Gravitational Wave Physics and Astronomy in the nascent era [PDF]

, 2023
The detections of gravitational waves (GW) by the LIGO/Virgo collaborations provide various possibilities for both physics and astronomy. We are quite sure that GW observations will develop a lot, both in precision and in number, thanks to the continuous
