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 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.

The ligo gravitational wave observatories: recent results and future plans [PDF]

open access: yes, 2005
The LIGO interferometers are operating as gravitational wave observatories, with a noise level near an order of magnitude of the goal and the first scientific data recently taken. This data has been analyzed for four different categories of gravitational

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: (

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 status of LIGO [PDF]

open access: yesAIP Conference Proceedings, 2000
Construction activities at the LIGO Observatories near Hanford, Washington and Livingston, Louisiana are complete. Installation of detector components and initial commissioning of detector sub-systems is now under way. The scope of the overall project is reviewed. The current status of the commissioning effort and future plans are outlined.

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.

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.
