Cosmological Tensions

PRL: Resolving cosmological tensions with reionization

Our joint first-author paper on the optical depth to reionization is out in Physical Review Letters.

Addressing Tensions in ΛCDM Cosmology by an Increase in the Optical Depth to Reionization

Joint first-author Phys. Rev. Lett. arguing that an upward shift in τ can absorb the DESI BAO vs CMB tension without new physics.

H₀ from the matter–radiation equality scale

A novel route to the Hubble constant that bypasses the sound horizon — using the matter–radiation equality scale instead.
