The 1σ and 2σ marginalized credible-interval contours for H0 with fEDE, ﹩{\mathrm{log}}_{10}{z}_{{\rm{c}}}﹩, ns, and S8 in the Axion-EDE model from the CMB, DESI, JWST, and SH0ES data. The horizontal shaded bands represent the local H0 measurement from SH0ES (light red) and the CMB-inferred value from Planck (light blue).
