Accelerating cosmological inference from cluster counts

The number counts of galaxy clusters selected with the South Pole Telescope are a powerful observational probe of the properties of the Dark Universe, especially when their mass scale is calibrated with weak gravitational lensing in wide photometric surveys like the Dark Energy Survey (Bocquet & Grandis et al., 2024a,b; Mazoun et al., 2024a). In the next decade, the team around Prof. Schrabback will contribute to analyzing 10 times larger cluster samples from surveys conducted with the third‑generation SPT camera. Their mass scale will be calibrated with WL data from the Euclid mission.
