EXTENDED CARBON LINE EMISSION IN THE GALAXY: SEARCHING FOR DARK MOLECULAR GAS ALONG THE G328 SIGHTLINE

ABSTRACT We present spectral data cubes of the [CI] 809 GHz, 115 GHz, 110 GHz, and HI 1.4 GHz line emission from a ∼1 square degree region along the (G328) sightline in the Galactic Plane. Emission arises principally from gas in three spiral arm crossings along the sightline. The distribution of emi...
