NEP-AKARI: Evolution with redshift of dust attenuation in 8 micron
  selected galaxies
  We built a 8um selected sample of galaxies in the NEP-AKARI field by defining
4 redshift bins with the four AKARI bands at 11, 15, 18 and 24 microns
(0.15<z<0.49, 0.75<z<1.34, 1.34<z<1.7 and 1.7<z<2.05) . Our sample contains
4079 sources, 599 are securely detected with Herschel/PACS. Also adding
ultraviolet (UV) data from GALEX, we fit the spectral energy distributions
using the physically motivated code CIGALE to extract the star formation rate,
stellar mass, dust attenuation and the AGN contribution to the total infrared
luminosity (L_{IR}). We discuss the impact of the adopted attenuation curve and
that of the wavelength coverage to estimate these physical parameters. We focus
on galaxies with a luminosity close the characteristic L_{IR}^* in the
different redshift bins to study the evolution with redshift of the dust
attenuation in these galaxies.
