Determining the primordial helium abundance and UV background using fluorescent emission in star-free dark matter haloes (2019)
Journal Article
Sykes, C., Fumagalli, M., Cooke, R., & Theuns, T. (2020). Determining the primordial helium abundance and UV background using fluorescent emission in star-free dark matter haloes. Monthly Notices of the Royal Astronomical Society, 492(2), 2151-2160. https://doi.org/10.1093/mnras/stz3573

Observational measures of the primordial helium mass fraction, YP, are of interest for cosmology and fundamental particle physics. Current measures obtained from HII HII regions agree with the Standard Model prediction to approximately 1% precision,...

The ACCELERATION programme: I. Cosmology with the redshift drift★ (2019)
Journal Article
Cooke, R. (2020). The ACCELERATION programme: I. Cosmology with the redshift drift★. Monthly Notices of the Royal Astronomical Society, 492(2), 2044-2057. https://doi.org/10.1093/mnras/stz3465

Detecting the change of a cosmological object’s redshift due to the time evolution of the Universal expansion rate is an ambitious experiment that will be attempted with future telescope facilities. In this paper, we describe the ACCELERATION program... Read More about The ACCELERATION programme: I. Cosmology with the redshift drift★.

The MUDF survey is collecting ≈150 h on-sourc... Read More about The MUSE Ultra Deep Field (MUDF). II. Survey design and the gaseous properties of galaxy groups at 0.5 < z < 1.5.

Modelling the chemical enrichment of Population III supernovae: The origin of the metals in near-pristine gas clouds (2019)
Journal Article
Welsh, L., Cooke, R., & Fumagalli, M. (2019). Modelling the chemical enrichment of Population III supernovae: The origin of the metals in near-pristine gas clouds. Monthly Notices of the Royal Astronomical Society, 487(3), 3363-3376. https://doi.org/10.1093/mnras/stz1526

The most metal-poor, high redshift damped Lyman-α systems (DLAs) provide a window to study some of the first few generations of stars. In this paper, we present a novel model to investigate the chemical enrichment of the near-pristine DLA population....

Fluorescent rings in star-free dark matter haloes (2019)
Journal Article
Sykes, C., Fumagalli, M., Cooke, R., Theuns, T., & Benítez–Llambay, A. (2019). Fluorescent rings in star-free dark matter haloes. Monthly Notices of the Royal Astronomical Society, 487(1), 609-621. https://doi.org/10.1093/mnras/stz1234

Photoheating of the gas in low-mass dark matter (DM) haloes prevents baryons from cooling, leaving the haloes free of stars. Gas in these ‘dark’ haloes remains exposed to the ultraviolet background (UVB), and so is expected to emit via fluorescent re... Read More about Fluorescent rings in star-free dark matter haloes.
