Title: Spectroscopic Survey of AKARI IR Sources in the North Ecliptic Pole

Abstract: We propose to perform a wide area (5.8 deg^2) spectroscopic survey of IR sources detected by the AKARI Infrared Space Telescope. The AKARI performed a 5.8 deg^2 IR imaging survey around the North Ecliptic Pole (NEP-Wide) offering contiguous IR imaging from 2.5 through 24 (micron) using 9 passbands including 11, 15, and 18 (micron) passbands where the Spitzer has limitations. The AKARI FIR data are also available in the NEP area to the depths comparable to Spizer wide area surveys. With the unique MIR coverage, NEP-Wide is currently the only wide-area IR survey that allows us to study the evolution of various MIR features from z=0 to z=2 such as PAHs, silicate absorptions, and power-slopes of AGNs, and their connection to IR-luminosity, star formation and AGN activities of more than thousands of IR sources. We will perform WIYN Hydra multi-object spectroscopic observations on 11/15/24 (micron) selected 900 optically bright sources - star forming galaxies, AGNs, early-type galaxies - to help determine the IR SED evolution as a function of redshift and environment, and also to determine IR luminosity functions at moderate redshift that can be directly compared with LF of z~2 galaxies from the Spitzer MIPS data.
