Characterization of magnetic field noise in the ARIADNE source mass rotor
Nancy Aggarwal, Allard Schnabel, Jens Voigt +19
ARIADNE is a nuclear-magnetic-resonance-based experiment that will search for novel axion-induced spin-dependent interactions between an unpolarized source mass rotor and a nearby…
Source mass characterization in the ARIADNE axion experiment
Chloe Lohmeyer, Nancy Aggarwal, Asimina Arvanitaki +22
The Axion Resonant InterAction Detection Experiment (ARIADNE) is a collaborative effort to search for the QCD axion using nuclear magnetic resonance (NMR), where the axion acts as…
Challenges and Opportunities of Gravitational Wave Searches at MHz to GHz Frequencies
N. Aggarwal, O. D. Aguiar, A. Bauswein +22
The first direct measurement of gravitational waves by the LIGO and Virgo collaborations has opened up new avenues to explore our Universe. This white paper outlines the challenges…
Searching for new physics with a levitated-sensor-based gravitational-wave detector
Nancy Aggarwal, George P. Winstone, Mae Teo +4
The Levitated Sensor Detector (LSD) is a compact resonant gravitational-wave (GW) detector based on optically trapped dielectric particles that is under construction. The LSD sensi…
Search for Gravitational Waves Associated with Gamma-Ray Bursts Detected by Fermi and Swift During the LIGO-Virgo Run O3a
The LIGO Scientific Collaboration, the Virgo Collaboration, R. Abbott +1250
We search for gravitational-wave transients associated with gamma-ray bursts detected by the Fermi and Swift satellites during the first part of the third observing run of Advanced…
Population Properties of Compact Objects from the Second LIGO-Virgo Gravitational-Wave Transient Catalog
The LIGO Scientific Collaboration, the Virgo Collaboration, R. Abbott +1338
We report on the population of the 47 compact binary mergers detected with a false-alarm rate 1/yr in the second LIGO--Virgo Gravitational-Wave Transient Catalog, GWTC-2. We observ…
Tests of General Relativity with Binary Black Holes from the second LIGO-Virgo Gravitational-Wave Transient Catalog
The LIGO Scientific Collaboration, the Virgo Collaboration, R. Abbott +1344
Gravitational waves enable tests of general relativity in the highly dynamical and strong-field regime. Using events detected by LIGO-Virgo up to 1 October 2019, we evaluate the co…
GWTC-2: Compact Binary Coalescences Observed by LIGO and Virgo During the First Half of the Third Observing Run
R. Abbott, T. D. Abbott, S. Abraham +1349
We report on gravitational wave discoveries from compact binary coalescences detected by Advanced LIGO and Advanced Virgo in the first half of the third observing run (O3a) between…
Properties and astrophysical implications of the 150 Msun binary black hole merger GW190521
The LIGO Scientific Collaboration, the Virgo Collaboration, R. Abbott +1254
The gravitational-wave signal GW190521 is consistent with a binary black hole merger source at redshift 0.8 with unusually high component masses, and $6…
GW190521: A Binary Black Hole Merger with a Total Mass of
The LIGO Scientific Collaboration, the Virgo Collaboration, R. Abbott +1253
On May 21, 2019 at 03:02:29 UTC Advanced LIGO and Advanced Virgo observed a short duration gravitational-wave signal, GW190521, with a three-detector network signal-to-noise ratio…
A room temperature optomechanical squeezer
Nancy Aggarwal
One of the noise sources that currently limits gravitational wave (GW) detectors comes from the quantum nature of the light causing uncertain amplitude and phase. Phase uncertainty…
GW190814: Gravitational Waves from the Coalescence of a 23 M Black Hole with a 2.6 M Compact Object
The LIGO Scientific Collaboration, the Virgo Collaboration, R. Abbott +1254
We report the observation of a compact binary coalescence involving a 22.2 - 24.3 black hole and a compact object with a mass of 2.50 - 2.67 (all measuremen…

The LIGO Scientific Collaboration, the Virgo Collaboration, R. Abbott +1254
We report the observation of gravitational waves from a binary-black-hole coalescence during the first two weeks of LIGO's and Virgo's third observing run. The signal was recorded…
GW190425: Observation of a Compact Binary Coalescence with Total Mass
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1199
On 2019 April 25, the LIGO Livingston detector observed a compact binary coalescence with signal-to-noise ratio 12.9. The Virgo detector was also taking data that did not contribut…
