The Secondary Spin Bias of Dark Matter Haloes
James W. Johnson, Ariyeh H. Maller, Andreas A. Berlind +2
We investigate the role of angular momentum in the clustering of dark matter haloes. We make use of data from two high-resolution N-body simulations spanning over four orders of ma…
The Three Hundred project: a large catalogue of theoretically modelled galaxy clusters for cosmological and astrophysical applications
Weiguang Cui, Alexander Knebe, Gustavo Yepes +34
We introduce the THE THREE HUNDRED project, an endeavour to model 324 large galaxy clusters with full-physics hydrodynamical re-simulations. Here we present the data set and study…
The Indirect Influence of Quasars on Reionization
Jacob Seiler, Anne Hutter, Manodeep Sinha +1
The exact role of quasars during the Epoch of Reionization remains uncertain. With consensus leaning towards quasars producing a negligible amount of ionizing photons, we pose an a…
Connecting and dissecting galaxies' angular momenta and neutral gas in a hierarchical universe: cue DARK SAGE
Adam R. H. Stevens, Claudia del P. Lagos, Danail Obreschkow +1
We explore the connection between the atomic gas fraction, f_atm, and `global disc stability' parameter, q, of galaxies within a fully cosmological context by examining galaxies in…
Likelihood Non-Gaussianity in Large-Scale Structure Analyses
ChangHoon Hahn, Florian Beutler, Manodeep Sinha +3
Standard present day large-scale structure (LSS) analyses make a major assumption in their Bayesian parameter inference --- that the likelihood has a Gaussian form. For summary sta…
