In an update of our recent paper with Aleksandr Chatrchyan, Florian Niedermann, and Vivian Poulin, we have included fits of Cold New Early Dark Energy (Cold NEDE) to the DESI BAO data. <\/p>\n\n\n\n
Using CMB Planck Plik data, DESI BAO, and Pantheon+ data, we find around 2-sigma evidence for NEDE (see upper left panel below), which is enhanced to 6-sigma evidence when including SH0ES supernovae data (see upper right panel below). <\/p>\n\n\n\n
Without including SH0ES data, a value of H0=73 km\/s\/Mpc, compatible with SH0ES findings, is allowed within 2-sigma\u00a0using Planck Plik, DESI BAO, and Pantheon+ data (see lower left panel below). Including SH0ES data, the Lambda-CDM preferred value of H0 less than 68 km\/s\/Mpc is excluded at 6-sigma in the Cold NEDE model.<\/p>\n\n\n\n
