The JCMT Nearby Galaxies Legacy Survey – IV. Velocity dispersions in the molecular interstellar medium in spiral galaxies
Abstract
An analysis of large‐area CO J= 3–2 maps from the James Clerk Maxwell Telescope for 12 nearby spiral galaxies reveals low velocity dispersions in the molecular component of the interstellar medium. The three lowest luminosity galaxies show a relatively flat velocity dispersion as a function of radius while the remaining nine galaxies show a central peak with a radial fall‐off within 0.2–0.4r25. Correcting for the average contribution due to the …
