Kelley Liebst AST 591 School of Earth and Space Exploration Arizona State University Galaxy clusters with Alma
ALMA Design Reference Plan • Galaxies and Cosmology • Star and Planet Formation • Stars and Their Evolution • Solar System • Mm VLBI
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
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?

Galaxy Clusters Image: Icke, 2004
ICM – ISM Interaction Image: van Gorkom, 2004
ICM – ISM Interaction Image: van Gorkom, 2004
ICM – ISM Interaction Image: van Gorkom, 2004
ICM – ISM Interaction Image: van Gorkom, 2004
ICM – ISM Interaction Image: Moore, 2004
Tidal Interactions • Tidal perturbation parameter (Varela, 2004)
Tidal Interactions Image: Icke, 1985
Mergers • It’s time for Youtube!
Mergers Without global tidal interaction With global tidal interaction Images: Mihos, 2004
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
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
Galaxy Clusters with ALMA • ALMA provides good resolution at wavelengths relevant to SZE (Kitayama et al., 2004)
Galaxy Clusters with ALMA Image: Kitayama et al., 2004
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
