Large-Scale Anisotropic Correlation Function of SDSS Luminous Red Galaxies
Teppei Okumura, Takahiko Matsubara, Daniel J. Eisenstein +4
We study the large-scale anisotropic two-point correlation function using 46,760 luminous red galaxies at redshifts 0.16 -- 0.47 from the Sloan Digital Sky Survey. We measure the c…
The Effect of Primordial Non--Gaussianity on the Topology of Large-Scale Structure
Chiaki Hikage, Peter Coles, Margherita Grossi +4
We study the effect of primordial non-Gaussianity on the development of large-scale cosmic structure using high-resolution N-body simulations. In particular, we focus on the topolo…
Galaxy clustering constraints on deviations from Newtonian gravity at cosmological scales II: Perturbative and numerical analyses of power spectrum and bispectrum
Akihito Shirata, Yasushi Suto, Chiaki Hikage +2
We explore observational constraints on possible deviations from Newtonian gravity by means of large-scale clustering of galaxies. We measure the power spectrum and the bispectrum…
