Calibrating the Nonlinear Matter Power Spectrum: Requirements for Future Weak Lensing Surveys
Dragan Huterer, Masahiro Takada
Uncertainties in predicting the nonlinear clustering of matter are among the most serious theoretical systematics facing the upcoming wide-field weak gravitational lensing surveys.…
Baryon Oscillations and Dark-Energy Constraints from Imaging Surveys
Derek Dolney, Bhuvnesh Jain, Masahiro Takada
Baryonic oscillations in the galaxy power spectrum have been studied as a way of probing dark-energy models. While most studies have focused on spectroscopic surveys at high redshi…
Effects of halo substructure on the power spectrum and bispectrum
Derek Dolney, Bhuvnesh Jain, Masahiro Takada
We study the effects of halo substructure and a distribution in the concentration parameter of haloes on large-scale structure statistics. The effects on the power spectrum and bis…
