A High-Finesse Suspended Interferometric Sensor for Macroscopic Quantum Mechanics with Femtometre Sensitivity

open access: yesSensors
We present an interferometric sensor for investigating macroscopic quantum mechanics on a table-top scale. The sensor consists of a pair of suspended optical cavities with finesse over 350,000 comprising 10 g fused silica mirrors.

Materials and Music: Selective Imperfection as a Generative Framework for Analysis, Creativity and Discovery

open access: yesInterdisciplinary Materials, Volume 5, Issue 5, Page 834-867, September 2026.
Vibrations in matter, from spider webs to molecules, water to flames, share a grammar with music. We propose that creativity emerges when constraints force expansion beyond existing possibilities. Selective imperfection restores balance, enabling invention.

Parallelized inference for gravitational-wave astronomy [PDF]

open access: yesPhysical Review D, 2019
Bayesian inference is the workhorse of gravitational-wave astronomy, for example, determining the mass and spins of merging black holes, revealing the neutron star equation of state, and unveiling the population properties of compact binaries. The science enabled by these inferences comes with a computational cost that can limit the questions we are ...

Surrogate Forward Models for Population Inference on Compact Binary Mergers

open access: yesThe Astrophysical Journal, 2023
Rapidly growing catalogs of compact binary mergers from advanced gravitational wave detectors allow us to explore the astrophysics of massive stellar binaries.

Attitude-Orbit Coupled Control of Gravitational Wave Detection Spacecraft with Communication Delays

open access: yesSensors, 2023
In order to meet the position and attitude requirements of spacecrafts and test masses for gravitational-wave detection missions, the attitude-orbit coordination control of multiple spacecrafts and test masses is studied.

Tropical cyclone‐induced estuarine destratification and protracted recovery

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 5, September 2026.
Abstract Estuarine stratification regulates nutrient cycling and ecosystem dynamics, yet its resilience to extreme meteorological events remains poorly understood. Here, we combine high‐resolution observations and numerical modeling to capture the full‐cycle physical response of an estuary to a summer typhoon.

A Search for Gravitational Waves from Perturbed Black Hole Ringdowns in LIGO Data [PDF]

open access: yes, 2008
According to General Relativity a perturbed black hole will return to a stable configuration by the emission of gravitational radiation in a superposition of quasi-normal modes. Such a perturbation will occur due to the coalescence of a black hole binary,

A Magnetospheric Source for Near‐Planet Whistler‐Mode Waves at Venus

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract The presence or absence of lightning in the atmosphere of Venus has important implications for atmospheric chemistry, potential chemical signatures of life, identifying volcanic activity, and quantifying potential hazards to future exploration missions.

Future Ground-Based Gravitational-Wave Observatories: Synergies with Other Scientific Communities [PDF]

open access: yes, 2021
Planning for the development of a 3rd generation global gravitational-wave detector array is a multifaceted and complex effort that will necessarily need a high level of community input.

From Nonparametric Distance Reconstruction to Testing the Etherington Relation and Cosmic Curvature Using 2D and 3D BAO Measurements

open access: yesThe Astrophysical Journal
We present a joint test of cosmic curvature, Ω _k _0 , and the cosmic distance–duality relation (CDDR) using the Etherington relation, which connects the luminosity and angular diameter distances at the same redshift. In this work, we combine the angular
