IM/EOR: INTENSITY MAPPING OF [CII] FROM THE EOR
• Detect aggregate clustering signal of faint galaxies in the epoch of reionization (EOR) via
redshifted [CII] 158 μm line.
• Directly traces sources of reionization (star forming galaxies) over the time interval of
“Cosmic Dawn”.
− Recent ALMA detection of [CII] in “normal” galaxies at z = 5-6 (e.g. Riechers et al., 2014,
ApJ 796, 84).
− Enhanced [CII] to dust continuum compared to lower redshifts à strong signal.
