The history of the cosmological reionization is still unclear. Two ionizing sources, stars and QSOs, are believed to play important roles during this epoch. Besides the 21 cm signals, the infrared emission from Pop III stars and X-ray photons from QSOs can be powerful probes of the reionization. Here we present a cross-correlation study of the 21c…
