Galaxy Cluster Mass Reconstruction Project: III. The impact of dynamical substructure on cluster mass estimates (2017)
Journal Article
Old, L., Wojtak, R., Pearce, F., Gray, M., Mamon, G., Sifón, C., …Saro, A. (2018). Galaxy Cluster Mass Reconstruction Project: III. The impact of dynamical substructure on cluster mass estimates. Monthly Notices of the Royal Astronomical Society, 475(1), https://doi.org/10.1093/mnras/stx3241

With the advent of wide-field cosmological surveys, we are approaching samples of hundreds of thousands of galaxy clusters. While such large numbers will help reduce statistical uncertainties, the control of systematics in cluster masses is crucial.... Read More about Galaxy Cluster Mass Reconstruction Project: III.

Cosmic CARNage I: on the calibration of galaxy formation models (2017)
Journal Article
Knebe, A., Pearce, F. R., Gonzalez-Perez, V., Thomas, P. A., Benson, A., Asquith, R., …Yi, S. K. (2018). Cosmic CARNage I: on the calibration of galaxy formation models. Monthly Notices of the Royal Astronomical Society, 475(3), https://doi.org/10.1093/mnras/stx3274

We present a comparison of nine galaxy formation models, eight semi-analytical, and one halo occupation distribution model, run on the same underlying cold dark matter simulation (cosmological box of comoving width 125h−1 Mpc, with a dark-matter part...

nIFTy cosmology: the clustering consistency of galaxy formation models (2017)
Journal Article
Pujol, A., Skibba, R. A., Gaztañaga, E., Benson, A., Blaizot, J., Bower, R., …Yi, S. K. (2017). nIFTy cosmology: the clustering consistency of galaxy formation models. Monthly Notices of the Royal Astronomical Society, 469(1), https://doi.org/10.1093/mnras/stx913

We present a clustering comparison of 12 galaxy formation models [including semi-analytic models (SAMs) and halo occupation distribution (HOD) models] all run on halo catalogues and merger trees extracted from a single _ cold dark matter N-body simul...
