Description: The study used cosmological 21-cm signals to estimate properties of Population III stars, such as their typical mass ($M_s$) and star formation efficiency ($f_*$). While constraints are possible under ideal conditions, accurate modeling of smooth foreground signals is crucial because they cause degeneracies that weaken the ability to precisely determine the Pop III parameters.
