Physical properties of molecular gas in the barred spiral galaxy NGC 2903 (Muraoka et al. 2016, PASJ, 68, 89).
Molecular gas density controls the difference of star formation efficiency (SFE) deriving spatially resolved molecular gas density and kinetic temperature and comparing them with SFE.
Transitions between atomic and molecular gas, diffuse and dense gas, gas and stars in the dwarf galaxy NGC 2976 (Hatakeyama et al. 2017, PASJ, 69, 67).
The molecular gas fraction depends on the surface densities of the total gas and the star formation rate, according to the main stellar disks of spiral galaxies.
