Abstract:
We present the first detailed analysis of three extragalactic fields
(IRAC Dark Field, ELAIS-N1, ADF-S) observed by the infrared satellite,
AKARI, using an optimised data analysis toolkit specifically for the
processing of extragalactic point sources. The InfaRed Camera (IRC) on
AKARI complements the Spitzer space telescope via its comprehensive
coverage between 8-24µm filling the gap between the Spitzer IRAC
and MIPS instruments.
Description:
Source counts in the AKARI bands at 3.2, 4.1, 7, 11, 15 and 18µm
are presented. At near-infrared wavelengths, our source counts are
consistent with counts made in other AKARI fields and in general with
Spitzer/IRAC (except at 3.2µm where our counts lie above). In the
mid-infrared (11-18µm) we find our counts are consistent with both
previous surveys by AKARI and the Spitzer peak-up imaging survey with
the InfraRed Spectrograph (IRS). Using our counts to constrain
contemporary evolutionary models we find that although the models and
counts are in agreement at mid-infrared wavelengths there are
inconsistencies at wavelengths shortward of 7µm, suggesting either
a problem with stellar subtraction or indicating the need for
refinement of the stellar population models. We have also investigated
the AKARI/IRC filters, and found an AGN selection criteria out to z<2
on the basis of AKARI 4.1, 11, 15 and 18µm colours.
