The
molecular gas reservoir of six low-metallicity galaxies from the Herschel Dwarf Galaxy Survey |
| Cormier et al. (2014) present CO observations
obtained at the ATNF Mopra 22-m, APEX, and IRAM 30-m telescopes in 6 nearby
low-metallicity galaxies. For the first time, they detect CO(1-0) in NGC625
and get strong limits for Haro11 and UM311 thanks to Mopra. While those
galaxies are forming stars, CO is faint. The molecular gas masses derived from
CO and dust methods are quite discrepant and stress the large uncertainties
on the true molecular mass present in these compact galaxies which may harbor
a significant reservoir of ``CO-dark'' molecular gas. |
