Squeezing the quantum noise of a gravitational-wave detector below the standard quantum limit
Wenxuan Jia, Victoria Xu, Kevin Kuns +168
Precision measurements of space and time, like those made by the detectors of the Laser Interferometer Gravitational-wave Observatory (LIGO), are often confronted with fundamental…
Correlated 1-1000 Hz magnetic field fluctuations from lightning over earth-scale distances and their impact on gravitational wave searches
Kamiel Janssens, Matthew Ball, Robert M. S. Schofield +9
We report Earth-scale distance magnetic correlations from lightning strokes in the frequency range 1-1000 Hz at several distances ranging from 1100 to 9000 km. Noise sources which…
Point absorbers in Advanced LIGO
Aidan F. Brooks, Gabriele Vajente, Hiro Yamamoto +198
Small, highly absorbing points are randomly present on the surfaces of the main interferometer optics in Advanced LIGO. The resulting nano-meter scale thermo-elastic deformations a…
Methods for Estimating Neutron Star Parameters using Multiple Mechanisms for Gravitational Wave Emission Associated with Pulsar Glitches
Matthew Ball, Raymond Frey
Several mechanisms for gravitational wave (GW) emission are believed to be associated with pulsar glitches. This emission may be split between long duration continuous waves and sh…
Prospects for Neutron Star Parameter Estimation using Gravitational Waves from f-modes Associated with Magnetar Flares
Matthew Ball, Raymond Frey, Kara Merfeld
Magnetar vibrational modes are theorized to be associated with energetic X-ray flares. Regular searches for gravitational waves from these modes have been performed by Advanced LIG…
Closing the AI Trust Gap: The Case for Independent Certification for Trustworthy AI
Trisevgeni Papakonstantinou, Cansu Canca, Farah Nanji +14
Over the past decade, responsible AI (RAI) has produced a substantial body of practice for identifying and mitigating the risks AI poses in high-stakes settings. Yet this work has…
Toward Automated Virtual Assembly for Prefabricated Construction: Construction Sequencing through Simulated BIM
Gilmarie O'Neill, Matthew Ball, Yujing Liu +2
To adhere to the stringent time and budget requirements of construction projects, contractors are utilizing prefabricated construction methods to expedite the construction process.…
Designing escalation criteria for international AI incident response: criteria, triggers, and thresholds
Francesca Gomez, Matthew Ball, Michael Harre +3
AI incident reporting requirements are emerging in regulation and policy, yet no operational criteria exist for determining when a detected AI incident warrants escalation beyond n…
Harmonizing AI Safety Thresholds
Wilber Sean Anterola, Matthew Ball, Luis F. Lafuerza +1
Frontier AI companies have published capability thresholds that differ substantially, making it difficult for third parties to verify whether a threshold has been crossed or to com…
