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 in…

nIFTY galaxy cluster simulations III: The Similarity & Diversity of Galaxies & Subhaloes

Pascal J. Elahi, Alexander Knebe, Frazer R. Pearce +17

We examine subhaloes and galaxies residing in a simulated LCDM galaxy cluster () produced by hydrodynamical codes ranging from classic…

Sussing Merger Trees: A proposed Merger Tree data format

Peter A. Thomas, Julian Onions, Dylan Tweed +13

We propose a common terminology for use in describing both temporal merger trees and spatial structure trees for dark-matter halos. We specify a unified data format in HDF5 and pro…

Major Mergers Going Notts: Challenges for Modern Halo Finders

Peter Behroozi, Alexander Knebe, Frazer R. Pearce +7

Merging haloes with similar masses (i.e., major mergers) pose significant challenges for halo finders. We compare five halo finding algorithms' (AHF, HBT, Rockstar, SubFind, and VE…

nIFTy Cosmology: Comparison of Galaxy Formation Models

Alexander Knebe, Frazer R. Pearce, Peter A. Thomas +33

We present a comparison of 14 galaxy formation models: 12 different semi-analytical models and 2 halo-occupation distribution models for galaxy formation based upon the same cosmol…

nIFTy galaxy cluster simulations I: dark matter & non-radiative models

Federico Sembolini, Gustavo Yepes, Frazer R. Pearce +24

We have simulated the formation of a galaxy cluster in a CDM universe using twelve different codes modeling only gravity and non-radiative hydrodynamics (\art, \arepo, \hydra\ a…
