Abstract:
The AMIGA project (Analysis of the Interstellar Medium of Isolated
Galaxies) is compiling a multiwavelength database of isolated galaxies
that includes optical (B and Hα), infrared (FIR and NIR) and radio
(continuum plus HI and CO lines) properties. It involves a refinement
of the pioneering Catalog of Isolated Galaxies (VII/82). This paper
is the first in a series and begins with analysis of the global
properties of the nearly redshift-complete Catalog of Isolated
Galaxies (CIG) with emphasis on the Optical Luminosity Function (OLF)
which we compare with other recent estimates of the OLF for a variety
of environments. The CIG redshift distribution for n=956 galaxies
re-enforces the evidence for a bimodal structure seen earlier in
smaller samples. The peaks at redshift near 1500 and 6000km/s
correspond respectively to galaxies in the local supercluster and
those in more distant large-scale components (particularly Perseus-
Pisces). The two peaks in the redshift distribution are superimposed
on 50% or more of the sample that is distributed in a much more
homogeneous way. The CIG probably represents the most homogeneous
local field example that has ever been compiled. Our derivation of the
CIG OLF is consistent with other studies of the OLF for lower density
environments. This comparison via the Schechter parameter
formalization shows that: 1) M* increases with galaxy surface density
on the sky and 2) α shows a weaker tendency to do the same. The
CIG represents the largest and most complete foundation for studies of
isolated galaxies and is likely as close as we can come to a field
sample.
