The Cosmic Microwave Background and $$H_0$$

open access: yes
The cosmic microwave background (CMB) offers a unique window into the early universe, providing insights into cosmological parameters like the Hubble constant. Recent precise measurements of the CMB by experiments like Planck seem to point to a lower value for the Hubble constant compared to some other measurements like those from Type Ia supernovae ...

The Cosmic Microwave Background Optical Depth Constrains the Duration of Reionization

open access: yesThe Astrophysical Journal Letters
Recently, it was pointed out that invoking a large value of the cosmic microwave background (CMB) optical depth, τ _CMB  = 0.09, could help resolve tensions between Dark Energy Survey Instrument DR2 baryon acoustic oscillation data and the CMB.
