Popis: | A study of the galactic structure has been made by deriving the brightness distribution of the galactic plane at 2.2 μm and 4.2 μm near infrared region using infrared objects detected by ground-based sky surveys. The infrared brightness distribution shows distinct peaks at every ∼8–12° galactic longitude and indicates a periodic structure. The one-to-one positional correlation observed between the periodic structure in 2.2 μm infrared brightness and the 2.6 mm CO emission line suggests that the near-infrared sources are strongly associated with dense clouds of molecular hydrogen distributed in the galactic plane. |
