cds-question@unistra.frmagellanic-cloudsstar-forming-regionsmolecular-cloudsco-line-emissioninterstellar-mediumWe present results of a wide-field (approximately 60x90pc) Atacama Large Millimeter/submillimeter Array mosaic of CO(2-1) and ^13^CO(2-1) emission from the molecular cloud associated with the 30 Doradus star-forming region in the Large Magellanic Cloud (LMC). Three main emission complexes, including two forming a bow-tie-shaped structure extending northeast and southwest from the central R136 cluster, are resolved into complex filamentary networks. Consistent with previous studies, we find that the central region of the cloud has higher line widths at a fixed size relative to the rest of the molecular cloud and to other LMC clouds, indicating an enhanced level of turbulent motions. However, there is no clear trend in gravitational boundedness (as measured by the virial parameter) with distance from R136. Structures observed in 13CO are spatially coincident with filaments and are close to a state of virial equilibrium. In contrast, 12CO structures vary greatly in virialization, with low CO surface brightness structures outside of the main filamentary network being predominantly unbound. The low surface brightness structures constitute ~10% of the measured CO luminosity; they may be shredded remnants of previously star-forming gas clumps, or alternatively the CO-emitting parts of more massive, CO-dark structures.2022ApJ...932...47Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/932/47CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/305 : SAGE LMC and SMC IRAC Source Catalog (IPAC 2009)J/AJ/136/18 : LMC SAGE.
