The Aemulus Project I: Numerical Simulations for Precision Cosmology
We show that these statistics are converged to 1% (2%) for halos with more than 500 (200) particles respectively and scales of r>200 ~ h^-1 kpc in real space or k ~ 3 h Mpc^-1 in harmonic space for z\le 1.

The Effect of Fiber Collisions on the Galaxy Power Spectrum Multipole
Using simulated mock catalogs, we demonstrate that fiber collisions have a significant impact on the power spectrum, $P(k)$, monopole and quadrupole that exceeds sample variance at scales smaller than $k\sim0. 1~h/Mpc$.

The clustering of galaxies in the completed SDSS-III Baryon Oscillation Spectroscopic Survey: cosmological analysis of the DR12 galaxy sample
When combined with supernova Ia data, we find H0 = 67. 3+/-1. 0 km/s/Mpc even for our most general dark energy model, in tension with some direct measurements.

Overview of the SDSS-IV MaNGA Survey: Mapping Nearby Galaxies at Apache Point Observatory
MaNGA will investigate the internal kinematic structure and composition of gas and stars in an unprecedented sample of 10, 000 nearby galaxies.
Mock galaxy catalogs using the quick particle mesh method
Sophisticated analysis of modern large-scale structure surveys requires mock catalogs.

Redshift-Space Distortions with the Halo Occupation Distribution II: Analytic Model
Using a series of collisionless N-body simulations, we demonstrate that the shape of this DF is determined primarily by the distribution of local densities around a halo pair, and at fixed density the velocity DF is close to Gaussian and nearly independent of halo mass.
