The Advanced LIGO Photon Calibrators [PDF]

open access: yes, 2016
The two interferometers of the Laser Interferometry Gravitaional-wave Observatory (LIGO) recently detected gravitational waves from the mergers of binary black hole systems.

Quantum-Enhanced Advanced LIGO Detectors in the Era of Gravitational-Wave Astronomy.

open access: yesPhysical Review Letters, 2019
The Laser Interferometer Gravitational Wave Observatory (LIGO) has been directly detecting gravitational waves from compact binary mergers since 2015. We report on the first use of squeezed vacuum states in the direct measurement of gravitational waves ...

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 ...

LIGO's "Science Reach"

open access: yes, 2001
Technical discussions of the Laser Interferometer Gravitational Wave Observatory (LIGO) sensitivity often focus on its effective sensitivity to gravitational waves in a given band; nevertheless, the goal of the LIGO Project is to ``do science ...

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.

Correlated noise in networks of gravitational-wave detectors: subtraction and mitigation [PDF]

open access: yes, 2014
One of the key science goals of advanced gravitational-wave detectors is to observe a stochastic gravitational-wave background. However, recent work demonstrates that correlated magnetic fields from Schumann resonances can produce correlated strain noise
