Search for Eccentric Black Hole Coalescences during the Third Observing Run of LIGO and Virgo [PDF]

open access: yesAstrophysical Journal, 2023
Despite the growing number of binary black hole coalescences confidently observed through gravitational waves so far, the astrophysical origin of these binaries remains uncertain.

Inference-Optimized AI and High Performance Computing for Gravitational Wave Detection at Scale

open access: yesFrontiers in Artificial Intelligence, 2022
We introduce an ensemble of artificial intelligence models for gravitational wave detection that we trained in the Summit supercomputer using 32 nodes, equivalent to 192 NVIDIA V100 GPUs, within 2 h.

Dependence of the detected signal on the kinematic parameters of the satellite in the S-LIGO-E2R space system

open access: yesДоклады Белорусского государственного университета информатики и радиоэлектроники, 2021
The changes of distances less than ~10–21 are registered during the gravitational wave experiment. This feature determines the minimum size of experimental installations and the frequency range of gravitational wave detectors.

GWTC-1: A Gravitational-Wave Transient Catalog of Compact Binary Mergers Observed by LIGO and Virgo during the First and Second Observing Runs [PDF]

open access: yes, 2018
We present the results from three gravitational-wave searches for coalescing compact binaries with component masses above 1$\mathrm{M}_\odot$ during the first and second observing runs of the Advanced gravitational-wave detector network. During the first

Advanced LIGO [PDF]

open access: yesClassical and Quantum Gravity, 2015
The Advanced LIGO gravitational wave detectors are second generation instruments designed and built for the two LIGO observatories in Hanford, WA and Livingston, LA. The two instruments are identical in design, and are specialized versions of a Michelson interferometer with 4 km long arms.

A Light in the Dark: Searching for Electromagnetic Counterparts to Black Hole–Black Hole Mergers in LIGO/Virgo O3 with the Zwicky Transient Facility [PDF]

open access: yesAstrophysical Journal, 2022
The accretion disks of active galactic nuclei (AGNs) are promising locations for the merger of compact objects detected by gravitational wave (GW) observatories. Embedded within a baryon-rich, high-density environment, mergers within AGNs are the only GW

Advanced LIGO Laser Systems for O3 and Future Observation Runs

open access: yesGalaxies, 2020
The advanced LIGO gravitational wave detectors need high power laser sources with excellent beam quality and low-noise behavior. We present a pre-stabilized laser system with 70 W of output power that was used in the third observing run of the advanced ...

Determination of absolute expression profiles using multiplexed miRNA analysis. [PDF]

open access: yesPLoS ONE, 2017
Accurate measurement of miRNA expression is critical to understanding their role in gene expression as well as their application as disease biomarkers. Correct identification of changes in miRNA expression rests on reliable normalization to account for ...
