| Abstract: |
The Exeter FCRAO CO Galactic Plane Survey consists of 12CO and 13CO (J=1–0)
observations over the Galactic plane covering 55°≤ ℓ ≤102°, |b|≥1°
and 141°≤ ℓ ≤195°, –3.5°≤ b ≤5.5° with a spatial resolution
of ∼ 45″ and a spectral resolution of ∼ 0.15 km s-1. We will present the
methodology of a threshold-based cloud and clump determination method which retains hierarchical
information, then discuss associating sources with clouds in the catalogue. Once complete, this
catalogue of clouds and clumps will encompass the majority of the Northern Galactic Plane, providing
knowledge of the molecular structure of the Galaxy and the starting point for studies of the
variation in star formation efficiency. In addition, it will allow us to identify clouds that have
no or little star formation taking place inside them, which are often overlooked in the study of
the conditions required for star formation to take place. |
