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 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)

Galaxy Clusters with ALMA
   ALMA provides good resolution at
    wavelengths relevant to SZE

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
