Simulations from COSMOS2020 show masking recovers [CII] above 300 GHz in ideal conditions but noise prevents useful S/N until near the end of 2000-hour observations.
Reviews how cross-correlating SKAO 21-cm LIM with other lines like [CII], CO, and Ly-alpha can mitigate systematics, enhance sensitivity, and disentangle cosmological from astrophysical parameters.
