A COSMOLOGICAL PAH SURVEY WITH SPICA

다국어 초록 (Multilingual Abstract)

We propose a cosmological survey to probe star formation and nuclear activityin galaxies at redshifts of z = 2 - 4 by polycyclic aromatic hydrocarbon(PAH) features usingthe SPICA mid-infrared instrument (SMI)with a spectral resolution of R = 20.
We will cover a wavelength range of 20-36 μmthat corresponds to z = 2 - 4 for the PAH features(11.3, 7.7, and 6.2 μm).
The sensitivity will be $1\times10^{-19}$ W/m$^2$ (5 $\sigma$)in case of a referencesurvey that covers 4 arcmin$^2$ field in a one-hour observation.
It corresponds to L$_{\rm IR}$=$2\times10^{11}$ $L_\odot$ at z=3and will give us more than 10000 galaxies in a 450 hour survey.
