Abstract:
We used SOFIA/GREAT [CII] 158um observations as well as HI data from
THINGS and CO(2-1) data from HERACLES to decompose the spectrally
resolved [CII] line profiles in NGC4124 into components associated
with neutral atomic and molecular gas. We infer gas masses traced by
[CII] under different ISM conditions. We find that the molecular gas
mass is dominated by CO-dark gas and that we can only assign 9 percent
of [CII] intensity to the cold neutral medium.
Description:
We provide SOFIA/GREAT [CII] spectra of five pointed positions in the
dwarf galaxy NGC4214. The data were reduced with GILDAS/CLASS and are
provided in Kelvin (Tmb scale).
