Abstract / Description:The [CII] 158 μm line is typically the brightest far-IR emission line from star-forming galaxies. As such, this line is a possible tracer of star-formation, but to do so we need the relative contributions of different ISM phases. Using high physical resolution observations of the [CII] 158 μm line from Herschel PACS in five 3'×3' field in M 31 and optical IFU spectra from PPaK and ancillary IR data, we are able to spatially separate out the ISM phases Kapala. We find that a large fraction of [CII] emission in M 31 arises from diffuse gas (~20-90), with a sub-linear relation of [CII]-SFR at ~50 pc scales. However, on ~kpc scales, the observed empirical [CII]-SFR relation is in agreement with other extragalactic studies.
