Catalogue of ¹²CO (J = 1-0) and ¹³CO (J = 1-0) molecular clouds in the Carina Flare supershell

We present a catalogue of ¹²CO(J = 1–0) and ¹³CO(J = 1–0) molecular clouds in the spatio-velocity range of the Carina Flare supershell, GSH287+04-17. The data cover a region of ~66 square degrees and were taken with the NANTEN 4m telescope, at spatial and velocity resolutions of ~2'.06 and 0.1 kms⁻¹. Decomposition of the emission results in the identification of 156 ¹²CO clouds and 60 ¹³CO clouds, for which we provide observational and physical parameters. Previous work suggests the majority of the detected mass forms part of a comoving molecular cloud complex that is physically associated with the expanding shell. The cloud internal velocity dispersions, degree of virialization and size-linewidth relations are found to be consistent with those of other Galactic samples. However, the vertical distribution is heavily skewed towards high-altitudes. The robust association of high-z molecular clouds with a known supershell provides some observational backing for the theory that expanding shells contribute to the support of a high-altitude molecular layer.19 page(s
