Abstract:
We summarize the updated set of multiphase chemical evolution models
performed with 44 theoretical radial mass initial distributions and 10
possible values of efficiencies to form molecular clouds and stars. We
present the results about the infall rate histories, the formation of
the disk, and the evolution of the radial distributions of diffuse and
molecular gas surface density, stellar profile, star formation rate
surface density, and elemental abundances of C, N, O, and Fe, finding
that the radial gradients for these elements begin steeper and flatten
with increasing time or decreasing redshift, although the outer disks
always show a certain flattening for all times. With the resulting
star formation and enrichment histories, we calculate the spectral
energy distributions (SEDs) for each radial region by using the ones
for single stellar populations resulting from the evolutive synthesis
model POPSTAR. With these SEDs we may compute finally the broad band
magnitudes and colors radial distributions in the Johnson and in the
SLOAN/SDSS systems which are the main result of this work. We present
the evolution of these brightness and color profiles with the
redshift.
Description:
These tables give the theoretical chemical and photometric evolution
of galaxies from the cited paper. Basically give tables 2, 3 and 4 for
the 440 models from Molla & Diaz (2005, Cat. J/MNRAS/358/521) and
Molla (2014AdAst2014E..13M). These models correspond to 44 different
galaxy dynamical mass defined by a number between 1 and 44 (see Table
1 from Molla & Diaz (2005, J/MNRAS/358/521) where properties for each
of these theoretical galaxy mass distributions are given). For each
one 10 different values of efficiences to form molecular clouds and
stars are used (see Table 2 from Molla & Diaz 2005, Cat.
J/MNRAS/358/521). Tables 2 and 3 refer to the chemical evolution
results, while table 4 give the photometric evolution. All tables give
the evolution of the different radial regions of theoretical galaxies,
this way it is necessary to integrate these results to obtain the
evolution of a galaxy as a whole.
