The stellar and hot gas content of low-mass galaxy clusters
Michael L. Balogh, Pasquale Mazzotta, Richard G. Bower +4
We analyse the stellar and hot gas content of 18 nearby, low-mass galaxy clusters, detected in redshift space and selected to have a dynamical mass 3E14<M/Msun<6E14, as measured fr…
A Halo Expansion (HEX) Technique for Approximating Simulated Dark Matter Haloes
Ben Lowing, Adrian Jenkins, Vincent Eke +1
We apply a basis function expansion method to create a time-evolving density/potential approximation of the late growth of simulated N-body dark matter haloes. We demonstrate how t…
Connected structure in the 2dFGRS
David N. A. Murphy, Vincent R. Eke, Carlos S. Frenk
We describe and apply a simple prescription for defining connected structures in galaxy redshift surveys. The method is based upon two passes with a friends-of-friends groupfinder.…
The Link between Galactic Satellite Orbits and Subhalo Accretion
Mark Lovell, Vincent Eke, Carlos Frenk +1
We calculate the orbital angular momentum of dark matter subhaloes in the Aquarius simulations of cold dark matter galactic haloes. We calculate the orientation of their angular mo…
