Constraining the origin and models of chemical enrichment in galaxy clusters using the Athena X-IFU
F. Mernier, E. Cucchetti, L. Tornatore +16
The chemical enrichment of the Universe at all scales is related to stellar winds and explosive supernovae phenomena. Metals produced by stars and later spread at the mega-parsec s…

Towards mapping turbulence in the intra-cluster medium -- II. Measurement uncertainties in the estimation of structure functions
E. Cucchetti, N. Clerc, E. Pointecouteau +2
X-ray observations of the hot gas filling the intra-cluster medium provide a wealth of information on the dynamics of clusters of galaxies. The global equilibrium of the ICM is bel…

Measuring turbulence and gas motions in galaxy clusters via synthetic Athena X-IFU observations
M. Roncarelli, M. Gaspari, S. Ettori +7
The X-ray Integral Field Unit (X-IFU) that will be on board the Athena telescope will provide an unprecedented view of the intracluster medium (ICM) kinematics through the observat…
