So, with a group of 7 we've been working these past two years on the reconstruction and cosmography of Cosmicflows-4, and the result will go public tomorrow, stay tuned!

Rising Tension.
Early Cosmicflows-4 result: R. Watkins+co-authors present an estimate of the bulk flow, the average velocity of the survey volume: about 400 km/s. This has an epsilonesque chance of occurring in the ΛCDM model with CMB derived parameters.
