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, 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.
