We use the first 10, 000 spectra of the zCOSMOS sample (I ≤ 22. 5) to study the role of galaxy stellar mass in the colour–density relation up to z = 1. We confirm that within a luminosity-limited sample (M B ≤ 20. 5 z) red galaxies reside mainly in high densities (δ) at...
quantification of significant non-linearities in the stellar mass–luminosity relation and evaluation of the bias due to unresolved binary systems (Kroupa et al. 1990, 1991, 1993). On the one hand this work lead to a detailed understanding of ...
Based on the comparison with galaxy evolution models, we find that the phenomena are well explained by the pure luminosity evolution of galaxies out to z~3.关键词: galaxies: evolution galaxies: fundamental parameters galaxies: high-redshift infrared: galaxies ...
It is shown that the mass-luminosity relation can be fitted by an analytical expression that is virtually universal with regard to the chemical composition and the energy generation law. A detailed comparison with the Eddington standard model is made. The application of the results obtained to the...
Globally, the orbits are isotropic in inner disk regions and become more radial as a function of radius, although this picture tends to depend on galaxy morphology and luminosity. The Milky Way orbital anisotropy profile measured from the Second Gaia Data Release is consistent with those of ...

The YSO mass function (MF), constructed using a theoretical mass-luminosity relation, shows peaks at substellar (0.08-0.18 M) and intermediate (1-1.78 M) mass ranges for the IRS 1-3 region. The MF can be fitted by a power law in the low-mass regime with a slope of Γ 0.54-0.75,...
It is correlated with the galaxy color indices, luminosity, and other parameters as de Vaucouleurs radius, inverse concentration index, etc. Understanding the relation between galaxies and their environment is a crucial part of understanding how galaxies form and evolve. Sign in to download full-...
