Anisotropic Clustering of Galaxies in High-z Universe as a Probe of
Dark Energy

Takahiko Matsubara

The anisotropic clustering of galaxies are considered as a powerful
probe of dark energy. The BAO encoded in galaxy clustering provides a
useful scale for this purpose. I will review a method of constraining
the dark energy using the anisotropic clustering of galaxies in high-z
universe. Our original method using the correlation function in high-z
space will be presented. Prospects for accurately modeling the BAO in
galaxy clustering will be discussed.
