Submillimeter Observations of IC 10: The Dust Properties and Neutral Carbon Content of a Low-Metallicity Starburst

We present submillimeter observations of the Local Group, metal-poor, irregular dwarf galaxy IC 10, directly relevant to the interaction between interstellar medium (ISM) and star formation activity in primeval galaxies. Using the James Clerk Maxwell Telescope, we have observed the fine-structure neutral carbon transition 3P1 → 3P0 at 492 GHz and the rotational J = 3 → 2 transition of 12CO and 13CO in the most massive giant molecular cloud …
