Determining the primordial helium abundance and UV background using fluorescent emission in star-free dark matter haloes
Calvin Sykes, Michele Fumagalli, Ryan Cooke +1
Observational measures of the primordial helium mass fraction, , are of interest for cosmology and fundamental particle physics. Current measures obtained from H II regi…
The ACCELERATION programme: I. Cosmology with the redshift drift
Ryan Cooke
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 tel…
MUSE Analysis of Gas around Galaxies (MAGG) -- I: Survey design and the environment of a near pristine gas cloud at z~3.5
Emma K. Lofthouse, Michele Fumagalli, Matteo Fossati +9
We present the design, methods, and first results of the MUSE Analysis of Gas around Galaxies (MAGG) survey, a large programme on the Multi Unit Spectroscopic Explorer (MUSE) instr…
The MUSE Ultra Deep Field (MUDF). II. Survey design and the gaseous properties of galaxy groups at 0.5 < z < 1.5
M. Fossati, M. Fumagalli, E. K. Lofthouse +12
We present the goals, design, and first results of the MUSE Ultra Deep Field (MUDF) survey, a large programme using the Multi Unit Spectroscopic Explorer (MUSE) instrument at the E…
Modelling the chemical enrichment of Population III supernovae: The origin of the metals in near-pristine gas clouds
Louise Welsh, Ryan Cooke, Michele Fumagalli
The most metal-poor, high redshift damped Lyman-alpha systems (DLAs) provide a window to study some of the first few generations of stars. In this paper, we present a novel model t…
Fluorescent rings in star-free dark matter haloes
Calvin Sykes, Michele Fumagalli, Ryan Cooke +2
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 ultra…
