XMM-Newton study of 0.012<z<0.024 groups. I: Overview of the IGM thermodynamics
A. Finoguenov, T. J. Ponman, J. P. F. Osmond +1
We study the thermodynamic properties of the hot gas in a sample of groups in the 0.012-0.024 redshift range, using XMM-Newton observations. We present measurements of temperature,…
The Group Evolution Multiwavelength Study (GEMS): the Sample and Datasets
Duncan A. Forbes, Trevor Ponman, Frazer Pearce +7
Galaxy groups have been under-studied relative to their richer counterparts -- clusters. The Group Evolution Multiwavelength Study (GEMS) aims to redress some the balance. Here we…
Cluster scaling and its redshift evolution from XMM-Newton
A. Finoguenov, H. Boehringer, J. P. F. Osmond +4
We put together the results of XMM-Newton observations of a number of representative group and cluster samples at low and high redshifts. These results confirm the entropy ramp as…
The unusual morphology of the intragroup medium in NGC 5171
John P. F. Osmond, Trevor J. Ponman, Alexis Finoguenov
We present the results of a 24 ks XMM-Newton observation of the NGC 5171 group of galaxies. NGC 5171 is unusual in that it is an X-ray bright group (L > 10^42 erg/s), with irregula…
The GEMS project: X-ray analysis and statistical properties of the group sample
John P. F. Osmond, Trevor J. Ponman
The GEMS project involves a multi-wavelength study of a sample of 60 galaxy groups. Substantial ROSAT PSPC observations are used to characterise the state of the intergalactic medi…
