Quantum-Enhanced Advanced LIGO Detectors in the Era of Gravitational-Wave Astronomy.

Physical Review Letters, 2019
The Laser Interferometer Gravitational Wave Observatory (LIGO) has been directly detecting gravitational waves from compact binary mergers since 2015. We report on the first use of squeezed vacuum states in the direct measurement of gravitational waves ...

A Magnetospheric Dichotomy for Pulsars with Extreme Inclinations

Universe, 2021
In this work, we expand on a comment by Lyne et al. (2017), that intermittent pulsars tend to congregate near a stripe in the logarithmic period versus period-derivative diagram.

Dark Energy in Light of Multi-Messenger Gravitational-Wave Astronomy [PDF]

Frontiers in Astronomy and Space Sciences, 2018
Gravitational waves (GWs) provide a new tool to probe the nature of dark energy (DE) and the fundamental properties of gravity. We review the different ways in which GWs can be used to test gravity and models for late-time cosmic acceleration. Lagrangian-

Evidence for a Correlation between Binary Black Hole Mass Ratio and Black Hole Spins

The Astrophysical Journal, 2023
The astrophysical origins of the binary black hole systems seen with gravitational waves are still not well understood. However, features in the distribution of black hole masses, spins, redshifts, and eccentricities provide clues into how these systems ...

Nuclear Physics with Gravitational Waves from Neutron Stars Disrupted by Black Holes

The Astrophysical Journal Letters, 2023
Gravitational waves from neutron star–black hole (NSBH) mergers that undergo tidal disruption provide a potential avenue to study the equation of state of neutron stars and hence the behavior of matter at its most extreme densities.

Quantum gravity and gravitational-wave astronomy [PDF]

Journal of Cosmology and Astroparticle Physics, 2019
We investigate possible signatures of quantum gravity which could be tested with current and future gravitational-wave (GW) observations. In particular, we analyze how quantum gravity can influence the GW luminosity distance, the time dependence of the ...

Exploring the Effects of Reduced Gravitational Field Impacts on Convective Heat Transfer: A Comprehensive Review

Heat Transfer, EarlyView.
ABSTRACT This review explores the impact of gravitational instability on convective heat transfer, integrating existing research results and theoretical models. Gravitational instability is vital in promoting or hindering convective actions in different systems, such as atmospheric events, ocean currents, and industrial processes.
