Can the sound horizon-free measurement of $H_0$ constrain early new physics?

2025 · arXiv (Cornell University)

The sound horizon-independent $H_0$ extracted by using galaxy clustering surveys data through, e.g., EFTofLSS or ShapeFit analyses, is considered to have the potential to constrain the early new physics responsible for solving the Hubble tension. …
