Speaker
Description
The abundance of galaxy clusters, the clustering of galaxies, and weak gravitational lensing are key observables of the cosmic large-scale structure. Over the past decade, tremendous progress was made in obtaining high-precision measurements, notably thanks to sensitive wide-field surveys of the cosmic microwave background and of galaxies and gravitational lensing. The abundance of clusters selected in data from the South Pole Telescope (SPT) — in combination with mass calibration based on weak-lensing data from the Dark Energy Survey (DES) and the Hubble Space Telescope — was shown to be compatible and complementary with analyses of galaxy clustering and weak lensing (3x2pt).
In my talk, I will review the SPT cluster cosmology program and discuss our results from lensing-informed abundance measurements. Building on this latest SPT analysis and on galaxy and shear two-point correlation function measurements in DES Year 3 data, I will present cosmological constraints from the joint analysis of these probes (SPT clusters + DES 3x2pt). The precision of these results highlights the benefits of multiwavelength multiprobe cosmology and our analysis paves the way for upcoming joint analyses of next-generation datasets.
