  1. Kelley Liebst AST 591 School of Earth and Space Exploration Arizona State University Galaxy clusters with Alma

  2. ALMA Design Reference Plan • Galaxies and Cosmology • Star and Planet Formation • Stars and Their Evolution • Solar System • Mm VLBI

  3. 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

  4. 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?

  8. ICM – ISM Interaction Image: van Gorkom, 2004

  9. ICM – ISM Interaction Image: van Gorkom, 2004

  10. ICM – ISM Interaction Image: van Gorkom, 2004

  11. ICM – ISM Interaction Image: van Gorkom, 2004

  12. ICM – ISM Interaction Image: Moore, 2004

  13. Tidal Interactions • Tidal perturbation parameter (Varela, 2004)

  14. Tidal Interactions Image: Icke, 1985

  15. Mergers • It’s time for Youtube!

  16. Mergers Without global tidal interaction With global tidal interaction Images: Mihos, 2004

  17. 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

  18. 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

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

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

  21. 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
