The European Southern Observatory (ESO) has organized an important online conference (22-26 June 2020) on the current significant tension in measuring the expansion rate of the Universe, i.e. the Hubble constant H0. The videos of each day’s talks and the panel discussions have been uploaded on YouTube by the organizers and are publicly available.
Below are the links to the summaries of all days of the meeting including links to specific parts of each speaker’s talk mainly for future personal reference, but hopefully useful for others as well.
