Outline
What are galaxy clusters? How do cluster galaxies interact with
their environment?ICM - ISM interactionTidal interactionMergers
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
