Title
New Determination of the Hubble Constant with Gaia EDR3, Further Evidence of Excess Expansion
Abstract
The Hubble constant remains one of the most important parameters in the cosmological model which can be used to probe the nature of dark energy, the properties of neutrinos and the scale of departures from flat geometry. By steadily improving the precision and accuracy of the Hubble constant, we now see evidence for significant deviations from the standard model, referred to as LambdaCDM, and thus the exciting chance, if true, of discovering new fundamental physics. I will review recent and expected progress.
