The 9 and 18 Micron Luminosity Function of Various Types of Galaxies with AKARI: Implication for the Dust Torus Structure of AGN

We present the 9 and 18μm luminosity functions (LFs) of galaxies at 0.006 ≤ z ≤ 0.8 (with an average redshift of ∼0.04) using the AKARI mid-infrared all-sky survey catalog. We selected 243 galaxies at 9μm and 255 galaxies at 18μm from the Sloan Digital Sky Survey (SDSS) spectroscopy region. These galaxies were then classified by their optical emission lines, such as the line width of Hα or by thei...
