Abstract:
We compute the properties of a sample of 221 local, early-type
galaxies with a spectral energy distribution (SED) modeling software,
CIGALEMC. Concentrating on the star-forming (SF) activity and dust
contents, we derive parameters such as the specific star formation
rate (sSFR), the dust luminosity, dust mass, and temperature. In our
sample, 52% is composed of elliptical (E) galaxies and 48% of
lenticular (S0) galaxies. We find a larger proportion of S0 galaxies
among galaxies with a large sSFR and large specific dust emission. The
stronger activity of S0 galaxies is confirmed by larger dust masses.
We investigate the relative proportion of active galactic nuclei
(AGNs) and SF galaxies in our sample using spectroscopic Sloan Digital
Sky Survey data and near-infrared selection techniques, and find a
larger proportion of AGN-dominated galaxies in the S0 sample than the
E one. This could corroborate a scenario where blue galaxies evolve
into red ellipticals by passing through an S0 AGN active period while
quenching its star formation. Finally, we find a good agreement
comparing our estimates with color indicators.
Description:
We base our work on a sample of 225 early-type galaxies from Temi et
al. 2009 (cat. J/ApJ/707/890). We present a large fraction of their
SED from the ultraviolet to the far-infrared (Tables 1-4). We
concentrate primarily on six instruments which span these wavelengths
and have extensive sky coverage: Galaxy Evolution Explorer (GALEX; see
Bianchi et al. 2001, cat. II/312) for the UV part, SDSS (see SDSS-DR9
in cat. V/139) for the optical, Two Micron All Sky Survey (2MASS;
Cutri et al. 2003, cat. II/246) and IRAC-Spitzer for the NIR and MIR,
and MIPS-Spitzer and IRAS for the mid and FIR. We also use public data
from Herschel-SPIRE when available (see Table4).

Note (1): Calculated on the unreddened, fitted SED by taking the ratio of the
average flux per frequency unit of the wavelength ranges 4000-4100Å (red
continuum) and 3850-3950Å (blue continuum) and matching this ratio to
the age calculated on Maraston models (Maraston, 2005MNRAS.362..799M 2005MNRAS.362..799M).
