6.6. The galactic bar and spiral arms
Published online by Cambridge University Press: 25 May 2016
Abstract
The inner Galaxy light distribution recovered non-parametrically from the COBE/DIRBE surface brightness data shows an elongated bulge set in a highly non-axisymmetric disk. Gas flows computed in the potential of the COBE bar/bulge and disk have been compared with HI and CO line observations. For the best values of the NIR mass-to-light ratio and pattern speed a good match to the tangent point locations of the inner Galactic spiral arms is obtained.
