描述Various kinds of masks obscure our view of our galaxy, the Milky Way, as well as of other galaxies. Masks of interstellar dust affect our measurements within galaxies, on scales ranging from individual supernovae to the galaxies themselves. The “mass mask” (our inability to image mass rather than light) gives astronomers a very incomplete picture of the size and structure of galaxies themselves, because we cannot image the dark matter which provides most of the galactic mass. Another mass is the “dynamical mask”: as galaxies form, much dynamical information is lost in the birthing process. A new thrust in research is to retrieve such information by means of chemical tagging. About 50 astronomers flew into Namibia in April 2010, to celebrate the 70th birthday of Professor K.C. Freeman, Fellow of the Royal Society. At age 70, Freeman, a father of dark matter in galaxies, continues to be one of planet’s most highly cited astronomers. The current volume affords readers a unique perspective on galaxies by probing the thoughts of some of the greatest astronomers of our age. Contributions focus on galaxies from within our Local Group to those in our high redshift Universe. Approximately 4

Kenneth Lyons Jones,H. Eugene Hoymeuch as rings, nuclear arms, nuclear bars, and asymmetries. We find a centrally peaked concentration in about 85% of the galaxies with typical size scales of about 0.5–1 kpc. This might be related to perturbations produced by recent interactions.

Regarding the bulge region we find that the ages and metallicities are younger and more metal rich, at a given ., than the bulges of unbarred galaxies. The bulges of the barred galaxies in our sam

The motions are highly anisotropic at large scales,with in-plane velocities being much more important than vertical ones.In contrast, at small scales, the motions become more isotropic.
