Secular evolution in the central regions of galaxies
arXiv:astro-ph/0109142
Abstract
In this paper, I mention a few processes which may play a role in the evolution of the central regions of galaxies. In this context, I briefly discuss some issues regarding the formation of bulges in spirals, the role of supermassive black holes, and the importance of nuclear density waves.
