Description
We measure the evolution of the X-ray luminosity-temperature (L_X_-T) relation since z~1.5 using a sample of 211 serendipitously detected galaxy clusters with spectroscopic redshifts drawn from the XMM Cluster Survey first data release (XCS-DR1). This is the first study spanning this redshift range using a single, large, homogeneous cluster sample. We compare our results to numerical simulations, where we fit simulated cluster samples using the same methods used on the XCS data.
