Secular Evolution of Galaxies

  title={Secular Evolution of Galaxies},
  author={F Combes Lerma},
In current ΛCDM galaxy formation scenarios, at least three physical phenomena could contribute to the mass assembly: monolithic collapse, hierarchical mergers and more quiescent external gas accretion, with secular evolution. The three processes are described, and their successes and problems are reviewed. It is shown that monolithic collapse is likely to be quite restricted to sub-components of galaxies, while the two main scenarii, hierarchical merging and secular evolution, might have… CONTINUE READING
