|Abstract:||Finally, we examine how scaling relations evolve with redshift using a 70 cluster sample over the redshift range 0.18 < z < 1.24. We show that X-ray luminosity and ICM mass evolve more slowly toward higher redshifts than is predicted by self-similar models of cluster formation. Effects of core structure are again apparent in this work, as scaling relations constructed from core subtracted quantities evolve differently from those using non-core subtracted quantities, and the scatter in scaling relations and in central surface brightness increases at low redshift.|
