The effect of spectral resolution on biosignature detection via reflected light observations of the Earth through time
Nominal HWO resolutions suffice to detect key biosignatures across Archean to Phanerozoic Earth atmospheres, with O3 enabling indirect low-O2 detection and NIR resolution preventing CO2-CO false positives.
