Galaxy Groups at Intermediate Redshift
Galaxy groups likely to be virialized are identified within the CNOC2 intermediate redshift galaxy survey using an iterative method. The resulting groups have a median velocity dispersion of about 200 km s−1. The virial mass-to-light ratios, using k-corrected and evolution-compensated luminosities, have medians in the range of 150 − 250hM⊙/L⊙. The number-velocity dispersion relation is in agree...
متن کاملHigh redshift galaxy surveys
A brief overview on the current status of the census of the early universe population is given. Observational surveys of high redshift galaxies provide direct opportunities to witness the cosmic dawn and to have better understanding of how and when infant galaxies evolve into mature ones. It is a much more astronomical approach in contrast to the physical approach of to study the spatial fluctu...
متن کاملThe 2dF Galaxy Redshift Survey: the clustering of galaxy groups
We measure the clustering of galaxy groups in the 2dFGRS Percolation-Inferred Galaxy Group (2PIGG) catalogue. The 2PIGG sample has 28 877 groups with at least two members. The clustering amplitude of the full 2PIGG catalogue is weaker than that of 2dFGRS galaxies, in agreement with theoretical predictions. We have subdivided the 2PIGG catalogue into samples that span a factor of ≈ 25 in median ...
متن کاملHigh Redshift Galaxy Clusters as Probes of Cosmology
A few, simple and qualitative examples of the potential of galaxy clusters as diagnostics of cosmology are presented. In relation to these we discuss briefly three ongoing or forthcoming cluster surveys in the optical/NIR, X-rays and the cosmic microwave radiation background.
متن کاملHigh-Redshift Quasars as Probes of Galaxy and Cluster Formation
Quasars at large redshifts provide a powerful probe of structure formation in the early universe. Several arguments suggest that the formation of ellipticals and massive bulges may have involved an early quasar phase. At very large redshifts, such structures are likely to be found at the highest peaks of the density field, and would thus be highly biased tracers: the earliest (massive) galaxy f...
