Observation of a kilogram-scale oscillator near its quantum ground state [PDF]

open access: yes, 2009
We introduce a novel cooling technique capable of approaching the quantum ground state of a kilogram-scale system—an interferometric gravitational wave detector.

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.

Parameter estimation for compact binary coalescence signals with the first generation gravitational-wave detector network [PDF]

open access: yes, 2013
Compact binary systems with neutron stars or black holes are one of the most promising sources for ground-based gravitational-wave detectors. Gravitational radiation encodes rich information about source physics; thus parameter estimation and model ...

The advanced LIGO input optics [PDF]

open access: yesReview of Scientific Instruments, 2016
The advanced LIGO gravitational wave detectors are nearing their design sensitivity and should begin taking meaningful astrophysical data in the fall of 2015. These resonant optical interferometers will have unprecedented sensitivity to the strains caused by passing gravitational waves. The input optics play a significant part in allowing these devices

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 Fermi GBM and LAT follow-up of GW150914

open access: yesEPJ Web of Conferences, 2017
As the first detection of Gravitation Wave (GW) event arising from the coalescence of two stellar-mass Black Holes (BH) was announced by LIGO, a new era for astronomy began.

GW200105 and GW200115 are compatible with a scenario of primordial black hole binary coalescences

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
Two gravitational wave events, i.e. GW200105 and GW200115, were observed by the Advanced LIGO and Virgo detectors recently. In this work, we show that they can be explained by a scenario of primordial black hole binaries that are formed in the early ...

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.
