Harvesting the Lyα forest with convolutional neural networks (2022)
Journal Article
Cheng, T., Cooke, R. J., & Rudie, G. (2022). Harvesting the Lyα forest with convolutional neural networks. Monthly Notices of the Royal Astronomical Society, 517, 755-775. https://doi.org/10.1093/mnras/stac2631

We develop a machine learning based algorithm using a convolutional neural network (CNN) to identify low H I column density Lyα absorption systems (log NHI/cm−2 < 17) in the Lyα forest, and predict their physical properties, such as their H I column...

A spectroscopic study of atomic oxygen (O I) is performed using the Fourier-transform vacuum ultraviolet (VUV) spectrometer at the Dichroïsme Et Spectroscopie par Interaction avec le Rayonnement Synchrotron beamline of the SOLEIL synchrotron. Transit... Read More about Vacuum Ultraviolet Fourier-transform Spectroscopy of 16O and 18O.

Primordial Helium-3 Redux: The Helium Isotope Ratio of the Orion Nebula* (2022)
Journal Article
Cooke, R. J., Noterdaeme, P., Johnson, J. W., Pettini, M., Welsh, L., Peroux, C., …Weinberg, D. H. (2022). Primordial Helium-3 Redux: The Helium Isotope Ratio of the Orion Nebula*. Astrophysical Journal, 932(1), Article 60. https://doi.org/10.3847/1538-4357/ac6503

We report the first direct measurement of the helium isotope ratio, 3He/4He, outside of the Local Interstellar Cloud, as part of science-verification observations with the upgraded CRyogenic InfraRed Echelle Spectrograph. Our determination of 3He/4He... Read More about Primordial Helium-3 Redux: The Helium Isotope Ratio of the Orion Nebula*.
