Advanced LIGO status

Journal of Physics: Conference Series, 2015
Advanced LIGO is currently in the final stages of installation and early commissioning. In the design of Advanced LIGO a key goal was the ability to detect gravitational waves from compact object binary inspirals, as these are thought to be the most likely candidates for early detections with ground based interferometers.

Discrepancy in tidal deformability of GW170817 between the Advanced LIGO twin detectors

Physical Review Research, 2019
We find that the Hanford and Livingston detectors of Advanced LIGO derive a distinct posterior probability distribution of binary tidal deformability Λ[over ̃] of the first binary-neutron-star merger GW170817.

Overview of Advanced LIGO adaptive optics

Applied Optics, 2016
This is an overview of the adaptive optics used in Advanced LIGO (aLIGO), known as the thermal compensation system (TCS). The thermal compensation system was designed to minimize thermally-induced spatial distortions in the interferometer optical modes and to provide some correction for static curvature errors in the core optics of aLIGO.

Polarization-Based Tests of Gravity with the Stochastic Gravitational-Wave Background

Physical Review X, 2017
The direct observation of gravitational waves with Advanced LIGO and Advanced Virgo offers novel opportunities to test general relativity in strong-field, highly dynamical regimes.

Multifaceted supercooling: from PTA to LIGO

Journal of High Energy Physics
Supercooled phase transitions, as predicted, e.g., in near-conformal and confining extensions of the Standard Model (SM), are established sources of strong stochastic gravitational wave backgrounds (SGWBs).

Rapid likelihood free inference of compact binary coalescences using accelerated hardware

Machine Learning: Science and Technology
We report a gravitational-wave parameter estimation algorithm, AMPLFI , based on likelihood-free inference using normalizing flows. The focus of AMPLFI is to perform real-time parameter estimation for candidates detected by machine-learning based compact

The LIGO–LIGO cross correlation for the detection of relic scalar gravitational waves [PDF]

New Astronomy, 2012
In the earlier work arXiv:0706.3782 we studied the cross correlation between the Virgo interferometer and the MiniGRAIL resonant sphere for the detection of relic scalar gravitational waves (SGWs). We have shown that the overlap reduction function for the cross correlation between Virgo and the monopole mode of MiniGRAIL is very small, but a maximum ...

LIGO and Science Diplomacy [PDF]

, 2020
The discovery of gravitational waves in LIGO captured the imagination of the public, worldwide. Why? The answer is one that is fundamental to the human race. A universal feature that sets humans apart from other living species is our curiosity about nature and the world we live in.

Searching for dark torsion signatures at LIGO in Nieh–Yan teleparallel chiral gravitational waves and Chern–Simons invariants

European Physical Journal C: Particles and Fields
Romano has recently found that frequency modulation of gravitational waves (GWs) could be used as a dark matter probe. Many candidates for dark matter (DM) of various sources have been proposed in the literature.

Multi-messenger astrophysics of black holes and neutron stars as probed by ground-based gravitational wave detectors: from present to future

Frontiers in Astronomy and Space Sciences
The ground-based gravitational wave (GW) detectors LIGO and Virgo have enabled the birth of multi-messenger GW astronomy via the detection of GWs from merging stellar-mass black holes (BHs) and neutron stars (NSs).
