The CI lines as tracers of molecular gas, and their prospects at high redshifts

Papadopoulos P. Padeli, Thi Wing-Fai, Viti Serena

We examine the fine structure lines ${}^3{P}_1\to$${}^3{P}_0$ (492 GHz) and ${}^3{P}_2\to$${}^3{P}_1$ (809 GHz) of neutral atomic carbon as bulk molecular gas mass tracers and find…
