The local volume: constraints on galaxy formation and evolution

Principal contact: R. Saglia ( )

Organisers: R. Bender, O. Gerhard, R. Saglia, J. Thomas (MPE, Garching, Germany),I. Ferreras, D. Kawata, S. Kaviraj (MSSL-UCL, UK)

The session is structured in three blocks, each 1.5 hours long, dealing with three topics: A) supermassive black holes and bars; B) Anisotropy, entropy and galaxy simulations; C) Dark matter and redshift evolution.

  1. will discuss the dynamical mass estimates of supermassive and intermediate mass black holes, the connection with the overall growth of galaxy bulges and the energy feedback mechanisms. Moreover, bars and disk instabilities driving secular evolution as a further mechanism for the formation and growth of galaxy bulges and their SMBHs will be considered.
  2. will assess our present understanding of the dynamical structure of galaxies, their entropy content and the role of dissipation in the formation process as a function of galaxy mass. N-body galaxy mergers and hybrid hydro-Nbody simulations in a cosmological context as tools to reach more realistic descriptions of galaxy merger processes will be reviewed.
  3. will survey galaxy dark matter properties coming from stellar dynamics, dynamical tracers, X-ray halo emission, strong gravitational lensing as probes of galaxy formation mechanisms, and confront them with the predictions of semi-analytic models.
