A statistical view on the galactic cold ISM distribution
Abstract
Inhomogenities were found in the distribution of the cold fraction in the interstellar medium (traced by Planck cold clumps). In large scales there is a significant overdensity on some shells, in small scales there are elongated groups. Critical column density for star formation is N(H2) = 7 × 1021 cm-2.
