"Cosmology with the Large-scale Structure of the Universe"

The large-scale structure (LSS) of the universe has been providing
valuable clues to elucidate the universe. In 1990s, the bubble-like
structures in the LSS suggested the existence of the cosmological
constant, before the discovery of the accelerated universe by
supernovae surveys. In 2000s, it was found that the LSS is one of the
most robust ways of constraining the nature of dark energy.
Ambitiously large, future galaxy surveys of LSS are proposed for that
purpose. Other fundamental physics such as the modified gravity,
generation of the primordial non-Gaussianity can also be probed by LSS
in such future surveys. I will review recent theoretical developments
of the LSS and some advanced topics that I have recently developed.
