Abstract
- AKARI is a survey-oriented infrared satellite observing in the near-, mid- and far-infrared wavelengths (at the same time) with an unprecedented angular resolution. It is an ideal tool to detect dusty galaxies, often invisible or barely visible in other bands. We present the first analysis of one of the deep AKARI fields: AKARI Deep Field South (ADF-S) located close to the South Ecliptic Pole and considered to be the most ideal sky area for far-infrared extragalactic observations. We made a cross-identification of 1000 90-μm ADF-S sources, and found counterparts for 545 of them. We found that the bulk of the brightest ADF-S sources are nearby galaxies, with a high percentage of interacting and peculiar galaxies. The composition of morphological types in the sample is close to the one expected for normal optically bright galaxies. We present the properties of these galaxies and discuss how this population of FIR-bright sources differs from an average local galaxy population and how it may affect our understanding of the role of dust in the star forming galaxies.
