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.

Gravitational waves from supercooled phase transitions in conformal Majoron models of neutrino mass

Journal of High Energy Physics
We study supercooled first-order phase transitions above the QCD scale in a wide class of conformal Majoron-like U(1)′ models that explain the totality of active neutrino oscillation data and produce a detectable stochastic gravitational wave background (

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.

Measuring neutron star tidal deformability with Advanced LIGO: a Bayesian analysis of neutron star - black hole binary observations

, 2017
The discovery of gravitational waves (GW) by Advanced LIGO has ushered us into an era of observational GW astrophysics. Compact binaries remain the primary target sources for LIGO, of which neutron star-black hole (NSBH) binaries form an important subset.

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.

Data Access for LIGO on the OSG

, 2017
During 2015 and 2016, the Laser Interferometer Gravitational-Wave Observatory (LIGO) conducted a three-month observing campaign. These observations delivered the first direct detection of gravitational waves from binary black hole mergers.

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 ...
