The X-ray luminosities of groups is less than expected if the gas were simply shock-heated during collapse. It is thought that a combination of gas cooling and energy injection decreases the amount of dense gas, reducing the luminosity. At present there is no unbiased sample of groups to reliably constrain such processes. This is because the samples are X-ray selected and therefore biased to X-ray luminous objects. We have constructed a complete mass-selected catalogue of groups identified in the Two Degree Field Galaxy Redshift Survey. X-ray observations of this sample would provide us with the first mass-selected census of group X-ray properties. In this pilot study we propose to observe two of the groups to demonstrate the reliability of selection and the feasibility of our approach.
