Structural thermal noise in gram-scale mirror oscillators

open access: yesNew Journal of Physics, 2012
The thermal noise associated with mechanical dissipation is a ubiquitous limitation to the sensitivity of precision experiments ranging from frequency stabilization to gravitational wave interferometry.

Deep learning ensemble for real-time gravitational wave detection of spinning binary black hole mergers

open access: yesPhysics Letters B, 2021
We introduce the use of deep learning ensembles for real-time, gravitational wave detection of spinning binary black hole mergers. This analysis consists of training independent neural networks that simultaneously process strain data from multiple ...

Potential tests of the generalized uncertainty principle in the advanced LIGO experiment

open access: yesPhysics Letters B, 2018
The generalized uncertainty principle and a minimum measurable length arise in various theories of gravity and predict Planck-scale modifications of the canonical position-momentum commutation relation.

Localizing compact binary inspirals on the sky using ground-based gravitational wave interferometers [PDF]

open access: yes, 2011
The inspirals and mergers of compact binaries are among the most promising events for ground-based gravitational-wave (GW) observatories. The detection of electromagnetic (EM) signals from these sources would provide complementary information to the GW ...

Compact Binary Coalescences: Astrophysical Processes and Lessons Learned

open access: yesGalaxies, 2022
On 11 February 2016, the LIGO and Virgo scientific collaborations announced the first direct detection of gravitational waves, a signal caught by the LIGO interferometers on 14 September 2015, and produced by the coalescence of two stellar-mass black ...

Matched filtering of gravitational waves from inspiraling compact binaries: Computational cost and template placement [PDF]

open access: yes, 1998
We estimate the number of templates, computational power, and storage required for a one-step matched filtering search for gravitational waves from inspiraling compact binaries.

Calibration Uncertainty for Advanced LIGO's First and Second Observing Runs [PDF]

open access: yes, 2017
Calibration of the Advanced LIGO detectors is the quantification of the detectors' response to gravitational waves. Gravitational waves incident on the detectors cause phase shifts in the interferometer laser light which are read out as intensity ...

Binary neutron star mergers with missing electromagnetic counterparts as manifestations of mirror world

open access: yesPhysics Letters B, 2020
We suggest that the major fraction of binary mergers, which might provide gravitational wave signal detectable by LIGO/VIRGO, emerged from the hidden mirror sector.

A Cryogenic Silicon Interferometer for Gravitational-wave Detection [PDF]

open access: yes, 2020
The detection of gravitational waves from compact binary mergers by LIGO has opened the era of gravitational wave astronomy, revealing a previously hidden side of the cosmos.
