Non-linear Evolution of Baryon Acoustic Oscillations from Improved Perturbation Theory in Real and Redshift Spaces
Atsushi Taruya, Takahiro Nishimichi, Shun Saito +1
We study the non-linear evolution of baryon acoustic oscillations in the matter power spectrum and correlation function from the improved perturbation theory (PT). Based on the fra…
Chasing the non-linear evolution of matter power spectrum with numerical resummation method: solution of closure equations
Takashi Hiramatsu, Atsushi Taruya
We present a new numerical scheme to treat the non-linear evolution of cosmological power spectra. Governing equations for matter power spectra have been previously derived by a no…
Non-linear Evolution of Matter Power Spectrum in Modified Theory of Gravity
Kazuya Koyama, Atsushi Taruya, Takashi Hiramatsu
We present a formalism to calculate the non-linear matter power spectrum in modified gravity models that explain the late-time acceleration of the Universe without dark energy. Any…
