Subhaloes gone Notts: Spin across subhaloes and finders
Julian Onions, Yago Ascasibar, Peter Behroozi +15
We present a study of a comparison of spin distributions of subhaloes found associated with a host halo. The subhaloes are found within two cosmological simulation families of Milk…
Constraining Extended Gamma-ray Emission from Galaxy Clusters
Jiaxin Han, Carlos S. Frenk, Vincent R. Eke +5
Cold dark matter models predict the existence of a large number of substructures within dark matter halos. If the cold dark matter consists of weakly interacting massive particles,…
Internal kinematics of groups of galaxies in the Sloan Digital Sky Survey data release 7
Cheng Li, Y. P. Jing, Shude Mao +5
We present measurements of the velocity dispersion profile (VDP) for galaxy groups in the final data release of the Sloan Digital Sky Survey (SDSS). For groups of given mass we est…
SubHaloes going Notts: The SubHalo-Finder Comparison Project
Julian Onions, Alexander Knebe, Frazer R. Pearce +14
We present a detailed comparison of the substructure properties of a single Milky Way sized dark matter halo from the Aquarius suite at five different resolutions, as identified by…
Evidence for extended gamma-ray emission from galaxy clusters
Jiaxin Han, Carlos S. Frenk, Vincent R. Eke +2
We report evidence for extended gamma-ray emission from the Virgo, Fornax and Coma clusters based on a maximum-likelihood analysis of the 3-year Fermi-LAT data. For all three clust…
