The Birth of a Galaxy: Primordial Metal Enrichment and Population II Stellar Populations
cosmology methods numerical hydrodynamics radiative transfer star formation
2010/11/15
Population III stars first form in dark matter halos with masses around 106M⊙. By definition,
they are metal-free, and their protostellar collapse is driven by molecular hydrogen cooling in the gas-p...
Testing a prediction of the merger origin of early-type galaxies: a correlation between stellar populations and asymmetry
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/29
One of the key predictions of the merger hypothesis for the origin of early-type (elliptical and lenticular) galaxies is that tidally-induced asymmetric structure should correlate with signatures of a...
Panchromatic Averaged Stellar Populations: PaasP
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/24
We study how the spectral fitting of galaxies, in terms of light fractions derived in one spectral region translates into another region, by using results from evolutionary synthesis models. In partic...
