Molecular Cloud Properties in the Galactic Longitude 45◦–60◦ and 120◦–130◦ revealed by MWISP

Based on unbiased 12CO, 13CO, and C18O (J=1–0) line emission data from the Milky Way Imaging Scroll Painting (MWISP), we identify and examine molecular clouds (MCs) in two regions of the inner (G50: 44.75◦ ≤ l ≤ 60.25◦) and outer (G120: 119.75◦ ≤ l ≤ 130.25◦) Galaxy. Both regions have Galactic latitudes of |b| ≤ 5.25◦. The MCs are identified as distinct contiguous structures in the 12CO data cube, and are further selected to be well-resolved and significant.

See the related paper (Zhou et al. 2026) for details. Full estimations of the observational, morphological, and derived physical parameters of the MCs are performed, and their distributions and correlations are examined and presented.
