The XMM-LSS survey: the Class 1 cluster sample over the initial 5 square degrees and its cosmological modelling
F. Pacaud, M. Pierre, C. Adami +30
We present a sample of 29 galaxy clusters from the XMM-LSS survey over an area of some 5deg2 out to a redshift of z=1.05. The sample clusters, which represent about half of the X-r…
Scaling relations in fossil galaxy groups
Habib G. Khosroshahi, Trevor J. Ponman, Laurence R. Jones
Using Chandra X-ray observations and optical imaging and spectroscopy of a flux-limited sample of 5 fossil groups, supplemented by additional systems from the literature, we provid…
The central elliptical galaxy in fossil groups and formation of BCGs
Habib G. Khosroshahi, Trevor. J. Ponman, Laurence R. Jones
We study the dominant central giant elliptical galaxies in ``Fossil groups'' using deep optical (R-band) and near infrared (Ks-band) photometry. These galaxies are as luminous as t…
A fossil galaxy cluster; an X-ray and optical study of RX J1416.4+2315
Habib G. Khosroshahi, Ben J. Maughan, Trevor J. Ponman +1
We present a detailed X-ray and optical study of a distant fossil system RX J1416.4+2315 (z=0.13), combining Chandra and XMM-Newton observations, optical photometry and spectroscop…
XMM observes ClJ0152.7-1357: A massive galaxy cluster forming at merger crossroads at z=0.83
B. J. Maughan, S. C. Ellis, L. R. Jones +3
We present an analysis of a 50ks XMM observation of the merging galaxy cluster ClJ0152.7-1357 at z=0.83. In addition to the two main subclusters and an infalling group detected in…
An analytic investigation of the scatter in the integrated X-ray properties of galaxy groups and clusters
Michael L. Balogh, Arif Babul, G. Mark Voit +4
(Abridged) We revisit the scaling relationships between the dark matter mass and observed X-ray luminosity and temperature of galaxy clusters and groups in the local Universe. Spec…
