The First Detection of Gravitational Waves

open access: yesUniverse, 2017
This article deals with the first detection of gravitational waves by the advanced Laser Interferometer Gravitational Wave Observatory (LIGO) detectors on 14 September 2015, where the signal was generated by two stellar mass black holes with masses 36

Targeted searches for gravitational waves from radio pulsars [PDF]

open access: yes, 2005
An overview of the searches for gravitational waves from radio pulsars with LIGO and GEO is given. We give a brief description of the algorithm used in these targeted searches and provide end-to-end validation of the technique through hardware injections.

Gravitational wave denoising of binary black hole mergers with deep learning

open access: yesPhysics Letters B, 2020
Gravitational wave detection requires an in-depth understanding of the physical properties of gravitational wave signals, and the noise from which they are extracted.

A radiometer for stochastic gravitational waves

open access: yes, 2005
The LIGO Scientific Collaboration recently reported a new upper limit on an isotropic stochastic background of gravitational waves obtained based on the data from the 3rd LIGO science Run (S3).

advligorts: The Advanced LIGO Real-Time Digital Control and Data Acquisition System [PDF]

open access: yes, 2020
The Advanced LIGO detectors are sophisticated opto-mechanical devices. At the core of their operation is feedback control. The Advanced LIGO project developed a custom digital control and data acquisition system to handle the unique needs of this new ...

Gravitational Wave Direct Detection does not Constrain the Tensor Spectral Index at CMB Scales

open access: yesThe Open Journal of Astrophysics, 2021
I discuss constraints on the power spectrum of primordial tensor perturbations from a combination of Cosmic Microwave Background (CMB) measurements and the gravitational wave direct detection experiments LIGO/Virgo and DECIGO. There are two main points: (

The updated DESGW processing pipeline for the third LIGO/VIRGO observing run [PDF]

open access: yesEPJ Web of Conferences, 2020
The DESGW group seeks to identify electromagnetic counterparts of gravitational wave events seen by the LIGO-VIRGO network, such as those expected from binary neutron star mergers or neutron star-black hole mergers.

Gravitational Wave Detectors: A report from LIGO-land

open access: yes, 2003
At the time of this conference, in June 2002, The LIGO Science Collaboration was getting ready to perform its first Science Run, where data will be taken with all three LIGO detectors. We describe here the status of the LIGO detectors as of February 2003,

The First Two Years of Electromagnetic Follow-Up with Advanced LIGO and Virgo [PDF]

open access: yes, 2014
We anticipate the first direct detections of gravitational waves (GWs) with Advanced LIGO and Virgo later this decade. Though this groundbreaking technical achievement will be its own reward, a still greater prize could be observations of compact binary ...
