Titel: Cosmological probe combination for current and future surveys

Speaker: Prof. Dr. Andrina Nicola, AIfA

Recent progress in observational cosmology and the establishment of ΛCDM have relied on the combination of different cosmological probes. These probes are not independent, since they all measure the same physical fields, and the resulting cross-correlations thus allow for robust tests of the cosmological model and for the characterization of systematics. In this talk, I will give an overview of the results of the Hyper Suprime Cam Year 3 Fourier-space cosmic shear analysis. In addition, I will discuss the potential of combining weak lensing with FRBs and secondary CMB anisotropies to constrain baryonic feedback effects on the matter distribution, which are a key systematic for both ongoing and upcoming surveys.
