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 alma1
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 alma2
Galaxy Clusters with ALMA

  • ALMA provides good resolution at wavelengths relevant to SZE

(Kitayama et al., 2004)

Conclutions
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
