Large velocity dispersion of molecular gas in bars of strongly barred galaxies NGC 1300 and NGC 5383

Maeda, Fumiya; Ohta, Kouji; Fujimoto, Yusuke; Habe, Asao; Baba, Junichi


We carried out 12CO(J = 1–0) observations toward bar and arm regions of the strongly barred galaxies NGC 1300 and NGC 5383 with the Nobeyama 45 m radio telescope (beam size of 1–2 kpc in the galaxies). The aim of the observations is to qualitatively examine a new scenario for the suppression of star formation in bars based on recent highresolution numerical simulations: higher speed collisions between molecular clouds in the bar region compared with the arm region suppress the massive star...[Show more]
