The evolution of the content of heavy elements in galaxies, the relative chemical
abundances, their spatial distribution, and how these scale with various galactic properties …

▪ Abstract The formation and evolution of galaxies is one of the great outstanding problems
of astrophysics. Within the broad context of hierachical structure formation, we have only a …

We present spectroscopic metallicities of individual stars in seven gas-rich dwarf irregular
galaxies (dIrrs), and we show that dIrrs obey the same mass–metallicity relation as the dwarf …

We present a new model for computing the spectral evolution of stellar populations at ages
between 1× 105 and 2× 1010 yr at a resolution of 3 Å across the whole wavelength range …

Galactic Bridges and Tails ADS Classic is now deprecated. It will be completely retired in
October 2019. This page will automatically redirect to the new ADS interface at that point …

Velocity dispersions for 25 E and S0 galaxies are presented which were measured by
employing conventional and Fourier techniques to reduce spectral data obtained in scans of …

We analyze the bivariate distribution, in color versus absolute magnitude (ur vs. M r), of a
low-redshift sample of galaxies from the Sloan Digital Sky Survey (2400 deg 2, 0.004< z< …

We derive stellar metallicities, light-weighted ages and stellar masses for a magnitude-
limited sample of 175 128 galaxies drawn from the Sloan Digital Sky Survey Data Release …

Chemical composition and evolution of irregular and blue compact galaxies ADS Classic is
now deprecated. It will be completely retired in October 2019. This page will automatically …

The DEEP2 and COMBO-17 surveys are compared to study luminosity functions of red and
blue galaxies to z~ 1. The two surveys have different methods and sensitivities, but …
