Multiprobe Cosmology - Robustness, Tensions, and Extensions to ΛCDM

Explore the robustness of multiprobe cosmological analyses and examine tensions within the standard ΛCDM model in this 17-minute conference talk by Alexander Reeves from ETH Zurich. Delve into cutting-edge methods for combining multiple observational probes to advance understanding of astrophysics and cosmology, including cosmic microwave background-large scale structure cross-correlations, galaxy clustering and lensing analyses, and measurements of the Integrated Sachs-Wolfe effect. Learn about state-of-the-art analysis techniques that leverage synergies between different cosmological observables, from radio and microwave to optical and X-ray wavelengths. Discover how multiprobe approaches can reveal potential extensions to the standard cosmological model and address current observational tensions. Gain insights into the latest developments in combining diverse astronomical surveys and datasets to test fundamental cosmological assumptions and explore new physics beyond the standard paradigm.
