The Origin of [CII] 157 μm Emission in a Five-component Interstellar Medium
The Case of NGC 3184 and NGC 628
With its relatively low ionization potential, C+ can be found throughout the interstellar medium (ISM) and provides one of the main cooling channels of the ISM via the [C ii] 157 μm emission. While the strength of the [C ii] line correlates with the star formation rate, the contr

The [C ii] 158 μm fine-structure line is the brightest emission line observed in local star-forming galaxies. As a major coolant of the gas-phase interstellar medium, [C ii] balances the heating, including that due to far-ultraviolet photons, which heat the gas via the photoel ...
We present [C ii] 158 μm measurements from over 15,000 resolved regions within 54 nearby galaxies of the Kingfish program to investigate the so-called [C ii] "line-cooling deficit" long known to occur in galaxies with different luminosities. The [C ii]/TIR ratio ranges from ab ...
Our observations include photometric and spectral-line observations from both the PACS and SPIRE instruments onboard Herschel, obtained as part of the large KINGFISH (Key Insights on Nearby Galaxies: a Far- Infrared Survey with Herschel, Kennicutt+ 2011PASP..123.1347K) and BtP (B

We have fit the far-ultraviolet (FUV) to sub-millimeter (850 μm) spectral energy distributions (SEDs) of the 61 galaxies from the Key Insights on Nearby Galaxies: A Far-Infrared Survey with Herschel (KINGFISH). The fitting has been performed using three models: the Code for Inves
