Description
Secular evolution gradually shapes galaxies by internal processes,in
contrast to early cosmological evolution which is more rapid.
Animportant driver of secular evolution is the flow of gas from the disk
into the central regions, often under the influence of a bar. In this
chapter we review several new observational results on barsand nuclear
rings in galaxies. They show that these components areintimately linked
to each other and to the properties of their hostgalaxy. We briefly
discuss how upcoming observations, e.g., imaging from the Spitzer Survey
of Stellar Structure in Galaxies (S4G), will lead to
significant further advances in this area of research.
