J/A+A/540/A47 AMIGA X. Isolated galaxy colors (Fernandez Lorenzo+, 2012) ================================================================================ The AMIGA sample of isolated galaxies. X. A first look at isolated galaxy colors. Fernandez Lorenzo M., Sulentic J., Verdes-Montenegro L., Ruiz J.E., Sabater J., Sanchez S. =2012A&A...540A..47F ================================================================================ ADC_Keywords: Galaxy catalogs ; Galaxies, photometry ; Morphology Keywords: galaxies: evolution - galaxies: interactions - galaxies: fundamental parameters - galaxies: general Abstract: The basic properties of galaxies can be affected by both nature (internal processes) or nurture (interactions and effects of environment). Deconvolving the two effects is an important current effort in astrophysics. Observed properties of a sample of isolated galaxies should be mainly the result of internal (natural) evolution. It follows that nurture-induced galaxy evolution can only be understood through a comparative study of galaxies in different environments. We take a first look at SDSS (g-r) colors of galaxies in the AMIGA sample, which consists of many of the most isolated galaxies in the local Universe. This alerted us at the same time the pitfalls of using automated SDSS colors. Description: Revision of the main properties for all AMIGA galaxies. Because a significant number of new data are available for the sample since the AMIGA project started, apparent magnitudes, morphological types, distances, and optical luminosities for the CIG sample have been updated. In the frame of the Wf4Ever project, the revision of these properties was partially automated by the implementation of scientific workflows that ask for and gather values of some of the properties for all AMIGA galaxies from the HyperLeda catalog.
