Resumen:
We present preliminary results on the morphological characterization of a new catalog of isolated galaxies obtained through an automated search in the Sloan Digital Sky Survey Data Release 5 (SDSS DR5). 1600 isolated galaxy candidates were found in ? 1.4 strad of sky in the (SDSS DR5) photometry. Our selection criteria, including a refined version of that in Karachentseva (1973), use a stronger isolation based on available redshift information. A deep and uniformly observed sample of isolated galaxies is aimed for various purposes including (i) comparative studies of environmental effects, (ii) confronting model predictions of galaxy evolution and (iii) evaluating the change of galaxy properties with redshift. © 2008: Instituto de Astronomía.
