54. Cosmological insights from the Dark Energy Survey

Daniel Gruen (LMU Munich)

The Dark Energy Survey has recently presented cosmological results from weak lensing and galaxy clustering two-point functions using data collected in the first three years of operations. The combination of area (>4000 deg^2) and depth (100 million lensing source galaxies observed) significantly exceeds the previous state of the art, requiring the development of new methodology in several...

28. The Hubble Tension

The Hubble constant (H0) is a key parameter in cosmology that sets the current expansion rate of the Universe. There is an intriguing tension between measurements of H0 from different methods. The tension could be due to errors in the measurements that are not yet accounted for. If this is ruled out, then new physics beyond the standard cosmological model would be needed to resolve the...
