Abstract:
We present new spatially resolved surface photometry in the
far-ultraviolet (FUV) and near-ultraviolet (NUV) from images obtained
by the Galaxy Evolution Explorer (GALEX) and IRAC1 (3.6µm)
photometry from the Spitzer Survey of Stellar Structure in Galaxies
(S4G). We analyze the radial surface brightness profiles µFUV,
µNUV, and µ[3.6], as well as the radial profiles of (FUV-NUV),
(NUV-[3.6]), and (FUV-[3.6]) colors in 1931 nearby galaxies (z<0.01).
The analysis of the 3.6 µm surface brightness profiles also allows
us to separate the bulge and disk components in a quasi-automatic way
and to compare their light and color distribution with those predicted
by the chemo-spectrophotometric models for the evolution of galaxy
disks of Boissier & Prantzos (2000MNRAS.312..398B 2000MNRAS.312..398B). The exponential
disk component is best isolated by setting an inner radial cutoff and
an upper surface brightness limit in stellar mass surface density. The
best-fitting models to the measured scale length and central surface
brightness values yield distributions of spin and circular velocity
within a factor of two of those obtained via direct kinematic
measurements. We find that at a surface brightness fainter than
µ[3.6]=20.89mag arcsec-2, or below 3x108M☉/kpc2 in
stellar mass surface density, the average specific star formation rate
(sSFR) for star-forming and quiescent galaxies remains relatively flat
with radius. However, a large fraction of GALEX Green Valley galaxies
show a radial decrease in sSFR. This behavior suggests that an
outside-in damping mechanism, possibly related to environmental
effects, could be testimony of an early evolution of galaxies from the
blue sequence of star-forming galaxies toward the red sequence of
quiescent galaxies.
Description:
The Spitzer Survey of Stellar Structure in Galaxies (S4G;
Sheth+ 2010, J/PASP/122/1397) galaxy sample is a deep infrared survey
of a (mainly) volume-limited sample of nearby galaxies within d<40Mpc
observed at 3.6 and 4.5um with the IRAC. In this paper, we have used
the surface photometry at 3.6um (IRAC1) measurements from the output
of pipeline 3 (P3) of the S4G sample (Munoz-Mateos+ 2015ApJS..219....3M 2015ApJS..219....3M).
We have collected these data from the IRSA database.
We gathered all available GALEX FUV and NUV images and related data
products for 1931 S4G galaxies that had been observed in at least one
of these two UV bands. We collected imaging data from all kinds of
surveys, such as the All-sky Imaging Survey, Medium Imaging Survey,
Deep Imaging Survey, and Nearby Galaxy Survey, as well as from Guest
Investigator (GIs/GIIs) Programs.

Note (2): The uncertainties do not include zero point errors, nor errors
associated to the misidentification of background or
foreground sources.
Note (3): From Munoz-Mateos et al. (2015ApJS..219....3M 2015ApJS..219....3M).
Note (4): Obtained by merging Tully+ (2013, J/AJ/146/86) and from the Galaxy
On Line Database Milano Network (GOLDMine,
Gavazzi+ 2003A&A...400..451G 2003A&A...400..451G) catalogs. When merging the two catalogs
into a single column, priority was given to the GOLDMine group ID.
That is, galaxies with a value of 1, 2, 3, 4, or 9 in the GOLDMine
catalog, denoting galaxies in the Virgo Cluster, were kept as such.
A value of 1 is assigned if the galaxy is in the Virgo Cluster at
17Mpc, 2 at 23 Mpc, 3 at 32 Mpc, 4 at 37.5 Mpc, and 9 for the ones at
various other distances. For galaxies not in GOLDMine, we use the
Tully group ID, but if the Tully group ID happens to be 1, 2, 3, 4,
or 9 (which does not necessarily mean that they are in the Virgo
Cluster), we append the value with the letter "T" to differentiate
them from the GOLDMine group ID. Only 11 out of 1931 galaxies have a
GOLDMine group ID of 0 but a Tully group ID of 1, 2, 3, 4, or 9,
namely: UGC07249 (1T), UGC07394 (4T), UGC07522 (4T), NGC4409 (4T),
NGC4496A (4T), IC0797 (1T), IC0800 (1T), PGC042160 (1T),
UGC07802 (1T), NGC4666 (9T), UGC07982 (2T).
A group ID of 0 means that the galaxy is not in a group in either
catalog.

Note (1): There are 1541 successful fits to the FN, F36, and N36 columns. There
are three galaxies with T < -3.5 (E galaxies, namely ESO548-023,
NGC4278, and NGC5173) that are included in the µ[3.6] vs kpc
column, bringing the total to 992 galaxies, but are removed from the
subsample for further analysis.
Note (2): Slope of linear fit and uncertainty obtained with
scipy.optimize.curve package. We applied the cutoffs at R/R80=0.5 and
µ[3.6]=23.5mag/arcsec2 only to the linear fit to the
µ[3.6] vs kpc data. In the case of colors, only the radial
cutoff at R/R80=0.5 is applied. We also applied a simple inclination
correction to the data by adding -2.5log10(b/a) where a and b are
the semi-major and semi-minor axes respectively. The slopes are in
units of mag/arcsec2/(R/R80).
