Abstract:
We present a study of the integrated properties of the 835 galaxies in
the Calar-Alto Legacy Integral Field spectroscopy Area survey. To
derive the main physical parameters of the galaxies we have fitted
their UV-to-IR spectral energy distributions (SEDs) with sets of
theoretical models using CIGALE. We perform a comparison of the
integrated galaxy parameters derived from multiband SED fitting with
those obtained from modelling the Integral Field Unit spectra and show
the clear advantage of using the SED-derived star formation rates
(SFRs). A detailed analysis of galaxies in the SFR/Mstar plane as a
function of their properties reveals that quenching of star formation
is caused by a combination of gas deficiency and the inefficiency of
the existing gas to form new stars. Exploring the plausible mechanisms
that could produce this effect, we find a strong correlation with
galaxy morphology and the build-up of central bulge. On the other
hand, the presence of Active Galactic Nucleus and/or a stellar bar, as
well as the local environment have only temporal effects on the
current star formation, a result also consistent with their
model-derived star formation histories.
Description:
The sample we use here comprises galaxies of the CALIFA survey
(Sanchez et al. 2016A&A...594A..36S 2016A&A...594A..36S, Cat. J/A+A/594/A36). This is a
survey of - originally - 630 (later extended to 1062) nearby galaxies
observed with the IFU instrument of the Calar-Alto 3.5m telescope. The
main criteria for the target selection of the original sample are
fully described in Walcher et al. (2014A&A...569A...1W 2014A&A...569A...1W).
We acquire the largest possible multiwavelength photometric data set
of all the objects within our sample from different public archives.
By construction all galaxies were included in the Sloan Digital Sky
Survey Data Release 7 (SDSS-DR7; Abazajian et al. 2009ApJS..182..543A 2009ApJS..182..543A,
Cat. II/294). Therefore, optical photometry is available for all of
them in the u', g', r', i', and z' bands. Near-infrared archival
photometry was acquired from the Two-Micron All Sky Survey Extended
Source Catalog archive (2MASS-XSC; Skrutskie et al.
2006AJ....131.1163S 2006AJ....131.1163S, Cat. VII/233). The galaxies were imaged in the J,
H, and Ks bands. Ultraviolet observations were obtained by the Galaxy
Evolution Explorer (GALEX; Martin & GALEX Science Team
2003AAS...203.9601M 2003AAS...203.9601M) in the FUV (1540Å) and NUV (2300Å) bands
simultaneously. The photometry was performed by Catalan-Torrecilla et
al. (2015A&A...584A..87C 2015A&A...584A..87C, Cat. J/A+A/584/A87). Finally, after a
careful examination we decided against using the available archival
data of the Wide Field Infrared Survey Explorer (WISE; Cutri et al.
2012yCat.2311....0C 2012yCat.2311....0C, Cat. II/311) since they were originally optimized
for point sources. We derived our own photometry using fixed apertures
which where defined by Catalan-Torrecilla et al. (2015A&A...584A..87C 2015A&A...584A..87C,
Cat. J/A+A/584/A87) for the 22µm (i.e. the lowest resolution) band
of WISE.
The final photometry used in this work is presented in Table 1. In
Table 2, we present the parameters of the 1062 galaxies.
