| Abstract: |
Measuring the barionic acoustic oscillation (BAO) of large scale structure is a promising method to set strong constraints on the nature of dark energy. In spectroscopic BAO surveys targeting emission line galaxies at high redshifts, it is required to select such emission line galaxies for spectroscopy efficiently from the imaging survey data. However, it is rather uncertain whether there are enough number of emission line galaxies for planned BAO surveys, and the requirements for imaging survey data for the pre-selection is not well known. Here, we estimate the surface number density of emission line galaxies by using the wide and deep data of the Subaru Deep Field (SDF) and the Subaru XMM-Newton Deep Survey (SXDS). We estimate the star formation rate and line luminosities (H alpha and OII) by SED fitting of the optical and NIR photometry data, and the method is calibrated by a test applied to the SDSS galaxies. The derived H alpha and OII luminosity functions (LFs) are compared with those by other methods. We will report some implications for future BAO surveys based on these results. |
