The hydrostatic mass bias in The Three Hundred clusters
  Hydrostatic equilibrium (HE) is often used in observations to estimate galaxy
clusters masses. We use a set of almost 300 simulated clusters from The Three
Hundred Project, to estimate the cluster HE mass and the bias deriving from it.
We study the dependence of the bias on several dynamical state indicators
across a redshift range from 0.07 to 1.3, finding no dependence between them.
Moreover, we focus our attention on the evolution of the HE bias during the
merger phase, where the bias even reaches negative values due to an
overestimation of the mass with HE.
