3 ALMA Design Reference Plan  Galaxies and Cosmology  Star and Planet Formation  Stars and Their Evolution  Solar System  Mm VLBI

4 ALMA Design Reference Plan  Galaxies and Cosmology The High-Redshift Universe Gravitational Lenses Quasar Absorption Lines Sunyaev-Zeldovich Effect with ALMA Gas in Galactic Nuclei The AGN Engine Galaxies in the Local Universe ALMA an the Magellanic Clouds Gamma Ray Bursts

5 Outline  What are galaxy clusters?  How do cluster galaxies interact with their environment? ICM - ISM interaction Tidal interaction Mergers  How will ALMA allow us to investigate this?

14 Tidal Interactions  Tidal perturbation parameter (Varela, 2004)

15 Tidal Interactions Image: Icke, 1985

16 Mergers  It’s time for Youtube!

17 Mergers Without global tidal interactionWith global tidal interaction Images: Mihos, 2004

18 Galaxy Clusters with ALMA  Galaxies and Cosmology Sunyaev-Zeldovich Effect with ALMA ○ Imaging galaxy cluster mergers via the Sunyaev-Zeldovich effect ○ Sunyaev-Zeldovich Effect of Galaxy Clusters at High Redshift

19 Galaxy Clusters with ALMA  Sunyaev-Zeldovich Effect = the inverse Compton scattering of the cosmic microwave background by hot elections (Kitayama et al., 2004) Images: SZA at Chicago

20 Galaxy Clusters with ALMA  ALMA provides good resolution at wavelengths relevant to SZE (Kitayama et al., 2004)

21 Galaxy Clusters with ALMA Image: Kitayama et al., 2004

22 Conclutions  Galaxies interact with each other and the ICM in clusters through ram- pressure stripping of the ISM, tidal interactions with other galaxies, and mergers with other galaxies  ALMA can probe the history of interactions in a cluster through the Sunyaev-Zuldovich Effect
