The X-ray Cluster Normalization of the Matter Power Spectrum
J. Patrick Henry, August E. Evrard, Henk Hoekstra +2
The number density of galaxy clusters provides tight statistical constraints on the matter fluctuation power spectrum normalization, traditionally phrased in terms of sigma_8, the…
Evidence for recent star formation in BCGs: a correspondence between blue cores and UV excess
A. Pipino, S. Kaviraj, C. Bildfell +3
We present a joint analysis of near-ultraviolet (NUV) data from the GALEX mission and (optical) colour profiles for a sample of 7 Brightest Cluster Galaxies (BCGs) in the Canadian…
The Role of the Radial Orbit Instability in Dark Matter Halo Formation and Structure
Jillian M. Bellovary, Julianne J. Dalcanton, Arif Babul +5
For a decade, N-body simulations have revealed a nearly universal dark matter density profile, which appears to be robust to changes in the overall density of the universe and the…
The impact of mergers on relaxed X-ray clusters - III. Effects on compact cool cores
Gregory B. Poole, Arif Babul, Ian G. McCarthy +2
(Abridged) We use the simulations presented in Poole et al. 2006 to examine the effects of mergers on compact cool cores in X-ray clusters. We propose a scheme for classifying the…
Resurrecting the Red from the Dead: Optical Properties of BCGs in X-ray Luminous Clusters
C. Bildfell, H. Hoekstra, A. Babul +1
We present measurements of surface brightness and colour profiles for the brightest cluster galaxies (BCGs) in a sample of 48 X-ray luminous galaxy clusters. These data were obtain…
The nature of the ghost cavity in the NGC 741 group
Nazirah N. Jetha, Martin J. Hardcastle, Arif Babul +4
We discuss the effects of energy injection into the intra-group medium of the group of galaxies associated with NGC 741. The X-ray emission reveals a large bubble, which in the abs…
