Abstract: |
[CII] 158 rm μm is an excellent probe of star formation activity of high-z galaxies.
Recent observations show interesting features such as line deficit of (U)LIRGs and even
non-detection for the UV luminous galaxies at z > 6. Theoretical approach holds promise in
order to reveal the statistical properties of the high-z [CII] emitters.
We develop theoretical model of [CII] emitters by combining a two-phase ISM model
and large cosmological hydrodynamic simulations. Our model explicitly calculates the effect
of dust attenuation of FUV radiation field (G0) using the three-dimensional distribution of the
star and gas elements in the simulated galaxies.
Our model reproduces observational correlation between [CII] luminosity and star formation rate at low-redshifts.
We discuss the detectability of high-z [CII] emitters with ALMA by using ALMA OT.
The results can be compared with near future observations. |
