Galaxy evolution in protoclusters

Λ CDM predictions for galaxy protoclusters I : The relation between galaxies , protoclusters and quasars at z ∼ 6

Motivated by recent observational studies of the environment of z ∼ 6 QSOs, we have used the Millennium Run (MR) simulations to construct a very large (∼ 4◦ × 4) mock redshift survey of star-forming galaxies at z ∼ 6. We use this simulated survey to study the relation between density enhancements in the distribution of i775-dropouts and Lyα emitters, and their relation to the most massive halos...

A Millimeter Continuum Survey for Massive Protoclusters in the Outer Galaxy

Our search for the earliest stages of massive star formation turned up twelve massive pre-protocluster candidates plus a few protoclusters. For this search, we selected 47 FIR-bright IRAS sources in the outer Galaxy. We mapped regions of several square arcminutes around the IRAS source in the millimeter continuum in order to find massive cold cloud cores possibly being in a very early stage of ...

High Redshift Clusters and Protoclusters

Our understanding of the cosmic history of galaxy clusters has recently been enhanced due to an extensive series of observations including faint spectroscopic data (especially those obtained at the Keck Observatory), deep optical and NIR imaging from the ground and in space, morphological data from HST, and new constraints on the evolution of the intracluster medium from ROSAT and ASCA. When su...
