SDSS VAGC

Stellar Population and Star Formation Rate

 * ASK Classification
 * Unsupervised classification of all galaxy spectra in the seventh and final Sloan Digital Sky Survey data release (SDSS/DR7) as described in Sánchez Almeida et al. (2010 ApJ 714,487S). 99% of the galaxies can be assigned to only 17 major classes, with 11 additional minor classes including the remaining 1%.

Morphology and Structure

 * Morphology 2010-Automated morphological classification of the SDSS DR7 sample
 * Catalog can be downloaded from Here (fits) and see Huertas-Company et al. 2010 for more details.
 * 698425 galaxies within z<0.25; probabilities of being E/S0 or Spiral; Also has more detailed classification probabilities (E, S0, Sab, Scd)


 * A Catalog of Detailed Visual Morphological Classifications for 14,034 Galaxies in the Sloan Digital Sky Survey
 * Paper by Nair & Abraham 2010, ApJS
 * Catalog can be found Here at VizieR


 * EFIGI-Extraction de Formes Idealisées de Galaxies en Imagerie
 * The EFIGI project proposes to address the computational aspects of galaxy morphometry and to develop a robust and scalable solution to measure galaxy morphologies for  numbers of objects in wide imaging surveys.
 * The EFIGI catalogue of 4458 galaxies extracted from the PGC and SDSS DR4 was designed to provide a multiwavelength reference database of the morphological properties of nearby galaxies.
 * The project paper on A&A: Paper I and Paper II
 * Technical paper based on this sample: An automatic method to determinate the degree of ﬂocculence of a galaxy

Galaxy Cluster

 * NAOC research on clusters of galaxies
 * 132,684 clusters from SDSS-III in the redshift range of 0.05<z<0.8
 * The catalog is available here
