Journal Article

A number of Local Group dwarf galaxies are known to have two spatially segregated stellar metallicity populations, a centrally concentrated metal-rich population and a more extended metal-poor population. In this work we discuss mechanisms that lead... Read More about The distinct stellar metallicity populations of simulated Local Group dwarfs.

The evolution of the UV-to-mm extragalactic background light: evidence for a top-heavy initial mass function? (2019)
Journal Article

The evolution of the UV-to-mm extragalactic background light: evidence for a top-heavy initial mass function?. Monthly Notices of the Royal Astronomical Society, 487(3), 3082-3101. https://doi.org/10.1093/mnras/stz1398

We present predictions for the UV-to-mm extragalactic background light (EBL) from a recent version of the GALFORM semi-analytical model of galaxy formation which invokes a top-heavy stellar initial mass function (IMF) for galaxies undergoing dynamica...

Halo concentrations from extended Press-Schechter merger histories (2019)
Journal Article
Benson, A. J., Ludlow, A., & Cole, S. (2019). Halo concentrations from extended Press-Schechter merger histories. Monthly Notices of the Royal Astronomical Society, 485(4), 5010-5020. https://doi.org/10.1093/mnras/stz695

We apply the model relating halo concentration to formation history proposed by Ludlow et al. to merger trees generated using an algorithm based on excursion set theory. We find that while the model correctly predicts the median relation between halo... Read More about Halo concentrations from extended Press-Schechter merger histories.

Correcting for fibre assignment incompleteness in the DESI Bright Galaxy Survey (2019)
Journal Article
Smith, A., He, J.-H., Cole, S., Stothert, L., Norberg, P., Baugh, C., Bianchi, D., Wilson, M. J., Brooks, D., Forero-Romero, J. E., Moustakas, J., Percival, W. J., Tarle, G., & Wechsler, R. H.

The Dark Energy Spectroscopic Instrument (DESI) Bright Galaxy Survey (BGS) will be a survey of bright, low-redshift galaxies, which is planned to cover an area of ∼14000 square degrees in three passes. Each pass will cover the survey area with ∼2000... Read More about Correcting for fibre assignment incompleteness in the DESI Bright Galaxy Survey.
