Detectability of the 21 cm-CMB cross-correlation from the EoR [PDF]

, 2009
The 21-cm line fluctuations and the cosmic microwave background (CMB) are powerful probes of the epoch of reionisation of the universe. We study the potential of the cross-correlation between 21-cm line fluctuations and CMB anisotropy to obtain further ...
