The Aemulus Project V: Cosmological constraint from small-scale clustering of BOSS galaxies

Understand

We analyze clustering measurements of BOSS galaxies using a simulation-based emulator of two-point statistics.

• We focus on the monopole and quadrupole of the redshift-space correlation function, and the projected correlation function, at scales of $0.1\sim60~h^{-1}$Mpc.
• Although our simulations are based on $w$CDM with general relativity (GR), we include a scaling parameter of the halo velocity field, $\gamma_f$, defined as the amplitude of the halo velocity field relative to the GR prediction.
• We divide the BOSS data into three redshift bins.
