| Abstract: |
We report the results of near-infrared (NIR) to mid-infrared (MIR) slit spectroscopic observations of the diffuse emission from the Large Magellanic Cloud (LMC) with the Infrared Camera (IRC) on board AKARI.
The present results suggest that the 3.3 μm Unidentified Infrared (UIR) band provides powerful information on the size distribution and/or the excitation conditions of PAHs.
A combination of the MIR bands with the 3.3 μm band, such as the diagram of I3.3/I11.3 v.s. I7.7/I11.3, is shown to be a useful diagnostic tool for the radiation conditions of the PAH emitting regions. |
