Clustering of far-infrared galaxies in the AKARI All-Sky Survey North

We present the measurements of the angular two-point correlation function for AKARI 90-$\mu m$ point sources, detected outside the Milky Way plane and other regions characterized by high Galactic extinction in the northern Galactic hemisphere, and categorized as extragalactic sources according to our far-infrared-color based criterion. Together with our previous work (Pollo et al., 2013) this is the first measurement of the large-scale angular clustering of galaxies selected in the far-infrared after IRAS. We present the first attempt to estimate the spatial clustering properties of AKARI All-Sky galaxies and we conclude that they are mostly a very nearby (z ≤ 0.1) population of moderately clustered galaxies. We measure their correlation length $r _{0} \sim 4.5 h ^{-1}$ Mpc, which is consistent with the assumption that the FIS AKARI All-Sky surveys observes mostly a nearby star-forming population of galaxies.
