ASP Conference Series vol. ASP Conference Series vol. They also completed a study of the relation between ionization cones and line emission, morphology and the distribution of ambient gas. The morphology of line emission in the extended emission line region can be determined by the ambient gas distribution.
Star formation can be an important source of infrared emission in clusters.
Some low surface brightness galaxies are red, and probably have normal and old stellar populations. No asymmetries were observed in contradiction to what was found previously in optical imaging. An elegant precessed warped disk model was constructed for the warped disk observed in M84. A. Quillen presented a short review of techniques which use asymmetries in galaxies to constrain stellar population mass to light ratios. We investigated the relationship between core shapes, gas content and environment.
