| Abstract: |
We observed an area of 10 deg2 of the Large Magellanic Cloud using the Infrared Camera (IRC) on board AKARI. The observations were carried out using five imaging filters (3.2, 7, 11, 15, and 24 μm) and a dispersion prism (2–5 μm, λ/Δλ∼20) equipped in the IRC. Here we describe an outline of our survey project, and present some initial results using imaging data that detected over 5.9×105 near-infrared and 6.4×104 mid-infrared point sources. The 10 σ detection limits of our survey are about 16.5, 14.0, 12.3, 10.8, and 9.2 in Vega-magnitude at 3.2, 7, 11, 15, and 24 μm, respectively. The first point source catalog is planned to be released to the public in 2009. We found a new sequence in the color-magnitude diagram, suggesting that this may be attributed to red giants with aluminum oxide dust but without silicate features. |
