New statistical measurements of  the 21-cm signal beyond the power spectrum

Abstract: 

The fluctuations in the 21-cm brightness temperature from the epoch of reionization are intrinsically non-Gaussian, due to patchy reionization. In principle, we can extract a wealth of information on cosmic reionization and ionizing sources from statistical measurements beyond the power spectrum, the quantity which has been investigated in many details in the 21-cm literature. I will report ongoing progresses on two new statistical quantities: (1) the 3-point correlation function of the 21-cm signal, (2) the dipole of the cross-correlation power spectrum between the 21-cm line and the CO(1-0) emission line.
