“…This conclusion that [CII] is mostly optically thin has been assumed several times since (e.g. Stacey et al 1991a;HaileyDunsheath et al 2010;Stacey et al 2010;De Breuck et al 2011;Rawle et al 2014).…”

“…The [CII] line can therefore be used to probe the stellar radiation field and how it affects the physical conditions of the gas. The bulk of the [CII] emission line (70% in Stacey et al 1991aStacey et al , 2010) is believed to originate from photodissociation regions (PDRs), and the remainder from X-ray dominated regions (XDRs), cosmic ray dominated regions (CRDRs), ionised regions (HII regions) (Meijerink et al 2007), low density warm gas and/or diffuse HI clouds (Madden et al 1997).…”

We present [CII] observations of 20 strongly lensed dusty star forming galaxies at 2.1 < z < 5.7 using APEX and Herschel. The sources were selected on their 1.4 mm flux (S 1.4 mm > 20 mJy) from the South Pole Telescope survey, with far-infrared (FIR) luminosities determined from extensive photometric data. The [CII] line is robustly detected in 17 sources, all but one being spectrally resolved. Eleven out of 20 sources observed in [CII] also have low-J CO detections from ATCA. A comparison with midand high-J CO lines from ALMA reveals consistent [CII] and CO velocity profiles, suggesting that there is little differential lensing between these species. The [CII], low-J CO and FIR data allow us to constrain the properties of the interstellar medium. We find [CII] to CO(1-0) luminosity ratios in the SPT sample of 5200 ± 1800, with significantly less scatter than in other samples. This line ratio can be best described by a medium of [CII] and CO emitting gas with a higher [CII] than CO excitation temperature, high CO optical depth τ CO (1-0) 1, and low to moderate [CII] optical depth τ [CII] 1. The geometric structure of photodissociation regions allows for such conditions.

“…Much H 2 is residing in photodissociation regions (PDRs). In fact PDRs may be the dominating phase in starburst nuclei [149]. PDRs contain ions of low ionisation potential, like C + , giving rise to the strong emission line [C II]λ 158µ.…”

Star forming dwarf galaxies (SFDGs) have a high gas content and low metallicities, reminiscent of the basic entities in hierarchical galaxy formation scenarios. In the young universe they probably also played a major role in the cosmic reionization. Their abundant presence in the local volume and their youthful character make them ideal objects for detailed studies of the initial stellar mass function (IMF), fundamental star formation processes and its feedback to the interstellar medium. Occasionally we witness SFDGs involved in extreme starbursts, giving rise to strongly elevated production of super star clusters and global superwinds, mechanisms yet to be explored in more detail. SFDGs is the initial state of all dwarf galaxies and the relation to the environment provides us with a key to how different types of dwarf galaxies are emerging. In this review we will put the emphasis on the exotic starburst phase, as it seems less important for present day galaxy evolution but perhaps fundamental in the initial phase of galaxy formation.
