Title
“Synthetic observations of clumpy ISM: Implications on the seed CO clouds and CO-dark molecular gas”
Abstract
We carried out synthetic observations of a theoretical model of interstellar carbon in CO, C I and C II including
H2 formation. The theoretical model based on numerical simulations of H I gas converging at a velocity of
20km/s by Inoue & Inutsuka (2012) is employed in the present study. The gas model, which is fairy realistic
and consistent with the observations of the local gas located at high b, is turbulent and inhomogeneous
with magnetic field. We focus on the evolution of the rare species, CO, C I and C II from 0.3 Myr to
9 Myr since the converging flows collided. In the early phase within 1 Myr, the Cold Neutral Medium (CNM)
clumps of sub-pc scales are the formation sites of H2, CO and C I, and in the late phase from 3 Myr to 9 Myr
the CNM clumps merge together to form pc-scale molecular clouds. The results show that C I and CO
are well mixed at pc scales, and mark a significant disagreement with the classic picture which predicts
layered C I and CO distributions according to Av. The total mass budget of the local ISM indicates
the fraction of H I is about 70% and the CO-dark H2 is small, less than a few percent, contrary to the usual
assumption. The results of high resolution CO observations by the Nobeyama 45m telescope, ASTE, and
ALMA obtained at a cloud edge are consistent with this picture, and future high resolution CI observations
by ALMA/ACA will reveal small-scale structures of molecular clouds and PDRs.
