Impact of systematics on cosmological parameters from future Galaxy Clusters surveys

Understand

Galaxy clusters are a recent cosmological probe.

• The precision and accuracy of the cosmological parameters inferred from these objects are affected by the knowledge of cluster physics, entering the analysis through the mass-observable scaling relations, and the theoretical description of their mass and redshift distribution, modelled by the mass function.
• In this work, we forecast the impact of different modelling of these ingredients for clusters detected by future optical and near-IR surveys.
• We consider the standard cosmological scenario and the case with a time-dependent equation of state for dark energy.
