The XMM Cluster Survey: evolution of the velocity dispersion -- temperature relation over half a Hubble time

We measure the evolution of the velocity dispersion--temperature (${\sigma }_{\mathrm{v}}$--$T_{\mathrm{X}}$) relation up to $z=1$ using a sample of 38 galaxy clusters drawn from the \textit{XMM}…
