2 Globular Clusters at High Redshift
Globular clusters will be present at high redshifts, near the very beginning of the galaxy formation process. Stellar evolution ensures that they will be much more luminous than today. We show that the redshift distribution at nano-Jansky levels should be very broad, extending up to the redshift of formation. A bracketing range of choices for the redshift of formation, spectral energy evolution...
متن کاملPrimordial pollution of globular clusters within their host dwarfs embedded in dark matter halos at high redshifts
Recent observational studies have revealed star-to-star abundance inhomogeneity among light elements (e.g., C, N, O, Na, and Al) of stars on the main sequence in the Galactic globular clusters (GCs). One of promising interpretations for this result is that the observed abundance inhomogeneity is due to the second generation of stars formed from ejecta of the first generation of evolved stars (e...
متن کاملGalaxies at High Redshifts
Several conclusions have been reached over the last few years concerning high-redshift galaxies: (1) The excess of faint blue galaxies is due to dwarf galaxies. (2) Star formation peaks at redshifts z ≈ 1 − 2. (3) It appears to occur piecemeal in any given galaxy and there is no evidence for starbursting throughout a large ∼ 10 kpc galaxy. (4) There is significant and sharp diminution in the nu...
متن کاملInfant Galaxy Clusters at Low Redshifts?
The population and population composition of galaxies in galaxy clusters at present reflect the mass of the clusters and the mass growth of the galaxies in the past. We investigate them for six clusters. We show that galaxies in massive clusters stopped growing at redshifts of ∼4. Moreover, we find that some small galaxy clusters (groups) have too many massive galaxies for their apparent masses...
متن کاملQuantitative Morphology at High Redshifts
The current evidence for morphologically peculiar galaxy populations at high-redshifts is outlined. After describing various techniques which can be used to quantify the importance of "morphological K-corrections", and to objectively classify galaxy morphology in the presence of these biases, it is concluded that observational biases are not sufficient to explain the increase in the fraction of...
