Non-linear Evolution of f(R) Cosmologies III: Halo Statistics
Fabian Schmidt, Marcos Lima, Hiroaki Oyaizu +1
The statistical properties of dark matter halos, the building blocks of cosmological observables associated with structure in the universe, offer many opportunities to test models…
Non-linear evolution of f(R) cosmologies II: power spectrum
Hiroaki Oyaizu, Marcos Lima, Wayne Hu
We carry out a suite of cosmological simulations of modified action f(R) models where cosmic acceleration arises from an alteration of gravity instead of dark energy. These models…
Non-linear evolution of f(R) cosmologies I: methodology
Hiroaki Oyaizu
We introduce the method and the implementation of a cosmological simulation of a class of metric-variation f(R) models that accelerate the cosmological expansion without a cosmolog…
Estimating the Redshift Distribution of Faint Galaxy Samples
Marcos Lima, Carlos E. Cunha, Hiroaki Oyaizu +3
We present an empirical method for estimating the underlying redshift distribution N(z) of galaxy photometric samples from photometric observables. The method does not rely on phot…
Cross-correlation Weak Lensing of SDSS Galaxy Clusters I: Measurements
Erin S. Sheldon, David E. Johnston, Ryan Scranton +12
This is the first in a series of papers on the weak lensing effect caused by clusters of galaxies in Sloan Digital Sky Survey. The photometrically selected cluster sample, known as…
A Galaxy Photometric Redshift Catalog for the Sloan Digital Sky Survey Data Release 6
Hiroaki Oyaizu, Marcos Lima, Carlos E. Cunha +3
We present and describe a catalog of galaxy photometric redshifts (photo-z's) for the Sloan Digital Sky Survey (SDSS) Data Release 6 (DR6). We use the Artificial Neural Network (AN…
