Caveats
No source-specific caveats are recorded.
Primordial Magnetic Fields (PMF) with strengths of 5-10 pico-Gauss at recombination accelerate ionization and shift the visibility function to earlier epochs, reducing sound horizon; MHD simulations with Lyman-α radiative transfer show 3σ preference for PMF-enhanced recombination (H₀ = 69.93 km/s/Mpc) when combined with Planck+DESI+SH0ES data.
