Title: Dynamical relaxation of galaxy groups and clusters
Abstract: In this talk, I will discuss some spectroscopic and photometric proxies used for determining the dynamical relaxation of galaxy groups/clusters. I will provide the results of employing these probes on simulations and observed data and compare them together. Finally, I will propose a bivariant relation which is a combination of the luminosity gap and luminosity decentering as a new possible proxy that can bring about promising results.
