Spatial Distribution of Stars, Dust and Gas in Nearby Galaxies: IFU Spectroscopy of NGC4654. American Astronomical Society, AAS Meeting #214, #419.10; . 2009, Vol. Bulletin of the American Astronomical Society, Vol. 41, p.689, p. -2009.
We present the results and future prospects of an extensive study of the
spatial distribution of stars, dust and gas in nearby galaxies, aimed at
understanding the assembly, evolution and interplay of these components
of spiral disks. As a first step we have derived the radial distribution
of dust properties (attenuation, PAH abundance, dust-to-gas ratio...)
from multi-wavelength observations of the SINGS galaxies. This study is
now being extended into a bi-dimensional approach by means of Integral
Field Spectroscopy data of a sample of nearby spirals, acquired with the
PPAK instrument at the 3.5m telescope in Calar Alto and with VIMOS at
VLT. We present preliminary results for one of the galaxies in our
sample, NGC4654. These IFS data, together with with already existing
GALEX and Spitzer imagery, will be used to derive the spatial
distribution of the physical properties of the underlying stellar
population (age, SFR, SFH...), gas (metallicity...) and dust
(attenuation, surface density...).
