UV Properties of Primeval Galaxies
The problem of UV properties of primeval galaxies is briefly assessed from the theoretical point of view discussing its impact on the definition of the cosmological model.
متن کاملExpected Properties of Primeval Galaxies and Confrontation with Existing Observations
1. Properties of low metallicity and PopIII starbursts – predictions and confrontation with existing observations Based on existing or new stellar tracks and appropriate non-LTE model atmospheres we have recently undertaken a systematic study of the expected restframe EUV, UV to optical properties of starbursts of zero and higher metal-licity (Schaerer 2002, 2003, hereafter S02, S03). These stu...
متن کاملThe Spectral Appearance of Primeval Galaxies
The current and forthcoming observations of large samples of high–redshift galaxies selected according to various photometric and spectroscopic criteria can be interpreted in the context of galaxy formation, by means of models of evolving spectral energy distributions (SEDs). We hereafter present stardust which gives synthetic SEDs from the far UV to the submm wavelength range. These SEDs are d...
متن کاملPhysical Properties and Environments of Nearby Galaxies
We review the physical properties of nearby, relatively luminous galaxies, using results from newly available massive data sets together with more detailed observations. First, we present the global distribution of properties, including the optical and ultraviolet (UV) luminosity, stellar mass, and atomic gas mass functions. Second, we describe the shift of the galaxy population from late galax...
متن کاملThe expected abundance of Lyman - α emitting primeval galaxies . I
We present model calculations for the expected surface density of Ly-α emitting primeval galaxies (PGs) at high redshifts. We assume that elliptical galaxies and bulges of spiral galaxies (= spheroids) formed early in the universe and that the Ly-α emitting PGs are these spheroids during their first burst of star formation at high redshift. One of the main assumptions of the models is that the ...
