Abstract:
The NEP-deep survey, an extragalactic AKARI survey towards the north
ecliptic pole (NEP), provides a comprehensive wavelength coverage from
2 to 24um using all 9 photometric bands of the infrared camera
(IRC). It allows us to photometrically identify galaxies whose mid-IR
emission is clearly dominated by PAHs.
We propose a single-colour selection method to identify such galaxies,
using two mid-IR flux ratios at 11-to-7um and 15-to-9um
(PAH-to-continuum flux ratio in the rest frame), which are useful for
identifying starburst galaxies at z∼0.5 and 1, respectively. We
perform a fitting of the spectral energy distributions (SEDs) from
optical to mid-IR wavelengths, using an evolutionary starburst model
with a proper treatment of radiative transfer (SBURT), in order to
investigate their nature.
Description:
Here we use the multi-wavelength data set of the AKARI NEP-deep
survey, described in detail in Wada et al. (2008PASJ...60S.517W 2008PASJ...60S.517W).
