The halo bispectrum as a sensitive probe of massive neutrinos and baryon physics
Victoria Yankelevich, Ian G. McCarthy, Juliana Kwan +2
The power spectrum has been a workhorse for cosmological studies of large-scale structure. However, the present-day matter distribution is highly non-Gaussian and significant cosmo…
Towards a universal model for the density profiles of dark matter haloes
Shaun T. Brown, Ian G. McCarthy, Sam G. Stafford +1
It is well established from cosmological simulations that dark matter haloes are not precisely self-similar and an additional parameter, beyond their concentration, is required to…
The BAHAMAS project: Evaluating the accuracy of the halo model in predicting the non-linear matter power spectrum
Alberto Acuto, Ian G. McCarthy, Juliana Kwan +3
The halo model formalism is widely adopted in cosmological studies for predicting the growth of large-scale structure in the Universe. However, to date there have been relatively f…
Testing extensions to LCDM on small scales with forthcoming cosmic shear surveys
Sam G. Stafford, Ian G McCarthy, Juliana Kwan +3
We investigate the constraining power of forthcoming Stage-IV weak lensing surveys (Euclid, LSST, and NGRST) for extensions to the LCDM model on small scales, via their impact on t…
Quenching of satellite galaxies of Milky Way analogues: reconciling theory and observations
Andreea S. Font, Ian G. McCarthy, Vasily Belokurov +2
The vast majority of low-mass satellite galaxies around the Milky Way and M31 appear virtually devoid of cool gas and show no signs of recent or ongoing star formation. Cosmologica…
Connecting the structure of dark matter haloes to the primordial power spectrum
Shaun T. Brown, Ian G. McCarthy, Benedikt Diemer +3
A large body of work based on collisionless cosmological N-body simulations going back over two decades has advanced the idea that collapsed dark matter haloes have simple and appr…
Informing dark matter direct detection limits with the ARTEMIS simulations
Robert Poole-McKenzie, Andreea S. Font, Billy Boxer +4
Dark matter (DM) direct detection experiments aim to place constraints on the DM--nucleon scattering cross-section and the DM particle mass. These constraints depend sensitively on…
The BAHAMAS project: Effects of dynamical dark energy on large-scale structure
Simon Pfeifer, Ian G. McCarthy, Sam G. Stafford +5
In this work we consider the impact of spatially-uniform but time-varying dark energy (or `dynamical dark energy', DDE) on large-scale structure in a spatially flat universe, using…
Exploring extensions to the standard cosmological model and the impact of baryons on small scales
Sam G. Stafford, Shaun T. Brown, Ian G. McCarthy +3
It has been claimed that the standard model of cosmology (LCDM) cannot easily account for a number of observations on relatively small scales, motivating extensions to the standard…
The BAHAMAS project: Effects of a running scalar spectral index on large-scale structure
Sam G. Stafford, Ian G. McCarthy, Robert A. Crain +5
Recent analyses of the cosmic microwave background (CMB) and the Lyman-alpha forest indicate a mild preference for a deviation from a power law primordial matter power spectrum (a…
