Dark Energy Survey Year Y6 Results Day!

This morning's arXiv announcement contained a number of papers related to the Dark Energy Survey Y6 analysis. There is also a Zoom webinar at 10.30 Central Time (16.30 GMT'; 13.30 in Greeland). Details can be found here. You can find links and abstracts to all the papers here, but I thought it would be useful to provide arXiv links to the latest batch here.

This is pretty big news in #cosmology (good news for LCDM, less good for people who liked the "S8 tension")

🥳 It's paper day for the completed #ESO Kilo-Degree Survey. We end our journey with a consistent picture of #cosmology 😲 I've been co-leading KiDS for 12yrs & I'm so proud of what the team's achieved. If you're at the #Euclid meet, go to Angus Wright's talk @10am today!🔭 ℹ️: arxiv.org/pdf/2503.19441

A two panel figure. The x-axis is omega_m, the fraction of matter in the Universe. The y-axis is S8 on the left and sigma_8 on the right. Both are measures of the 'clumpiness' of dark matter. The contours show that the KiDS data (two measurements using slightly different statistics, COSEBIs and Bandpowers) agree with the data from the Planck CMB survey.
