A recent paper from the GEI presents the first convolutional neural network (CNN) analysis pipeline for the detection of generic transient gravitational waves signals, with sensitivity across a wide range of signal parameters, used for real-time searches in data from the LIGO and Virgo detectors.
Screenshot of the paper: "Toward real-time detection of unmodeled gravitational wave transients using convolutional neural networks" By Vasileios Skliris, Michael R. K. Norman, and Patrick J. Sutton. Physical Review D 110, 104034 – Published 15 November, 2024. 5 types of gravitational wave signals which were injected into real LIGO-Virgo detector data in order to test the efficiency of the detection algorithm: a high frequency white noise burst (WNB), binary black hole merger (BBH), core-collapse supernova (CCSN), circularly polarized sine-Gaussian (CSG), and a cosmic string cusp (CUSP).

The first Gregynog Relativity Workshop was held at Gregynog Hall in Mid Wales, September 1-3, 1975. The topic was Thermodynamic Properties of Gravitational Fields.

Photos from our Quantum-Enhanced Space-Time (QUEST) experiment. This experiment searches for stochastic gravitational waves. The photos were taken by PhD student, Abhinav Patra, who has been working on QUEST in one of our laboratories at the Gravity Exploration Institute, Cardiff University.
Bird's-eye view of a part of the experiment. There are two cylinders on a table, with pipes/tubes coming out the side of them, and there are many wires around. At the bottom of the photo are the pink crocs of the scientist taking the photo. A physics laboratory with a lot of instruments on a table and vertical wires hanging everywhere. The instruments include cylinders and lasers.
