Atomic Hydrogen Shows its True Colours: Correlations between HI and Galaxy Colour in Simulations
Intensity mapping experiments are beginning to measure the spatial distribution of neutral atomic hydrogen (HI) to constrain cosmological parameters and the large-scale distribution of matter. However, models of the behaviour of HI as a tracer of matter are complicated by galaxy evolution. In this work, we examine the clustering of HI in relation to galaxy colour, stellar mass, and HI mass in IllustrisTNG at $z$ = 0, 0.5, and 1. We compare the HI-red and HI-blue galaxy cross-power spectra, find…

Star formation exists in all early-type galaxies -- evidence from ubiquitous structure in UV images
Recent surveys have demonstrated the widespread presence of UV emission in early-type (elliptical/S0) galaxies, suggesting the presence of star formation in many of these systems. However, potential UV contributions from old and young stars, together with model uncertainties, makes it challenging to confirm the presence of young stars using integrated photometry alone. This is particularly true in ETGs that are fainter in the UV and have red UV-optical colours. An unambiguous way of disentangli…
