Stefano Ettori, astrophysicist


I work on the formation and evolution of Clusters of Galaxies, focusing my activities on two main topics:

  1. +the physical properties of the Intra-Cluster Medium from the core to the outskirts where mass accretion is occurring;

  2. +the use of Galaxy Clusters as cosmological probes through the measurement of their baryonic and dark matter content.

Current main projects:

  1. -CHEX-MATE: 3 Msec with XMM-Newton obtained in the 2017 Multi-year Heritage Program call (PI: M. Arnaud & S. Ettori) to analyze the ultimate sample of 118 Planck SZ-selected objects, comprising an unbiased census of both the population of clusters at the most recent time (z < 0.2) and the most massive objects to have formed thus far in the history of the Universe, to study the culmination of cosmic structure formation;

  2. -X-COP: an XMM-Newton Very Large program dedicated to the study of the X-ray emission in the outskirts of twelve massive local galaxy clusters;

  3. -CLUster Multi-Probes in Three Dimensions (CLUMP-3D): to infer unbiased measurements of mass distribution, intrinsic shape and equilibrium status of galaxy clusters by exploiting rich multi-bands data-sets.

  4. -Guest Editor of Universe Special Issue The Physical Properties of the Groups of Galaxies (2021)
