The Cosmic Microwave Background Optical Depth Constrains the Duration of Reionization
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. This is larger than the value of τ _CMB = 0.058 measur...
