Abstract:
We present a detailed analysis of the radial distribution of dust
properties in the SINGS sample, performed on a set of ultraviolet
(UV), infrared (IR), and HI surface brightness profiles, combined with
published molecular gas profiles and metallicity gradients. By
applying physical dust models to our radial spectral energy
distributions, we have derived radial profiles of the total dust mass
surface density, the fraction of the total dust mass contributed by
polycyclic aromatic hydrocarbons (PAHs), and the intensity of the
radiation field heating the grains.
Description:
The SINGS sample (Kennicutt et al. 2003PASP..115..928K 2003PASP..115..928K) consists of 75
nearby galaxies. Eighteen SINGS galaxies were not suitable for our
purposes and were excluded from the present study. Nearly all SINGS
galaxies have been observed in the far-UV (FUV; λeff=151.6nm)
and near-UV (NUV; λeff=226.7nm) by GALEX (see Table 1). The
reader is referred to Paper I (2009, Cat. J/ApJ/703/1569) for a more
detailed description of the Spitzer data used here. Mid- and far-IR
observations of the SINGS sample were carried out using the Spitzer
Space Telescope (IRAC and MIPS). The HI Nearby Galaxy Survey (THINGS;
Walter et al. 2008, Cat. J/AJ/136/2563) used the Very Large Array
(VLA) to map HI 21cm line emission from 34 nearby (D<15Mpc) galaxies,
most of which were also targets of SINGS and the GALEX Nearby Galaxies
Survey.

Note (1): Indicates value is not reliable in regions where the dust
contribution to the observed 8 micron flux is less than half of the
stellar emission at that band.
Note (2): U is the intensity of the radiation field, expressed in units
of the local Milky Way (MW) radiation field.
