Scientific paper

CO data concerning three barred spiral galaxies, e.g., Maffei 2, NGC 2903, and NGC 253, have been analyzed to obtain the radial distribution of the CO surface density. The radial distribution demonstrates a strong peak at the galactic centers, and a secondary peak at distances of a few kiloparsec from the center, that are very similar to the Galaxy. The numerical simulations and observational results suggest that the Galaxy has a barred shape.
