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…

Estimating the Redshift Distribution of Photometric Galaxy Samples II. Applications and Tests of a New Method

Carlos E. Cunha, Marcos Lima, Hiroaki Oyaizu +2

In Lima et al. 2008 we presented a new method for estimating the redshift distribution, N(z), of a photometric galaxy sample, using photometric observables and weighted sampling fr…

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…

Photometric Redshift Error Estimators

Hiroaki Oyaizu, Marcos Lima, Carlos E. Cunha +2

Photometric redshift (photo-z) estimates are playing an increasingly important role in extragalactic astronomy and cosmology. Crucial to many photo-z applications is the accurate q…
