nIFTy galaxy cluster simulations II: radiative models
Federico Sembolini, Pascal Jahan Elahi, Frazer R. Pearce +19
We have simulated the formation of a massive galaxy cluster (M = 1.110) in a CDM universe using 10 different codes (RAMSES, 2 i…
Rendering Dark Energy Void
Sean February, Julien Larena, Mathew Smith +1
Dark energy observations may be explained within general relativity using an inhomogeneous Hubble-scale depression in the matter density and accompanying curvature, which evolves n…
LADUMA: Discovery of a luminous OH megamaser at
Marcin Glowacki, Jordan D. Collier, Amir Kazemi-Moridani +65
In the local Universe, OH megamasers (OHMs) are detected almost exclusively in infrared-luminous galaxies, with a prevalence that increases with IR luminosity, suggesting that they…
Galaxy correlations and the BAO in a void universe: structure formation as a test of the Copernican Principle
Sean February, Chris Clarkson, Roy Maartens
A suggested solution to the dark energy problem is the void model, where accelerated expansion is replaced by Hubble-scale inhomogeneity. In these models, density perturbations gro…
nIFTy galaxy cluster simulations V: Investigation of the Cluster Infall Region
Jake Arthur, Frazer R. Pearce, Meghan E. Gray +19
We examine the properties of the galaxies and dark matter haloes residing in the cluster infall region surrounding the simulated CDM galaxy cluster studied by Elahi et al. (201…
nIFTy Galaxy Cluster simulations IV: Quantifying the Influence of Baryons on Halo Properties
Weiguang Cui, Chris Power, Alexander Knebe +21
Building on the initial results of the nIFTy simulated galaxy cluster comparison, we compare and contrast the impact of baryonic physics with a single massive galaxy cluster, run w…
