Journal ArticleDOI
Baryonic features in the matter transfer function
TL;DR: In this article, scaling relations and fitting formulae for adiabatic cold dark matter cosmologies that account for all baryon effects in the transfer function to better than 10% in the large-scale structure regime were provided.
Journal ArticleDOI
Models of f(R) Cosmic Acceleration that Evade Solar-System Tests
Wayne Hu,Ignacy Sawicki +1 more
TL;DR: In this paper, the authors study a class of metric-variation models that accelerates the expansion without a cosmological constant and satisfies both cosmologically and solar-system tests in the small-field limit of the parameter space.
Journal ArticleDOI
Fuzzy cold dark matter: the wave properties of ultralight particles.
TL;DR: These problems might be solved, and the virtues of CDM models retained, even without postulating ad hoc dark matter particle or field interactions, if the dark matter is composed of ultralight scalar particles initially in a (cold) Bose-Einstein condensate, similar to axion dark matter models.
Journal ArticleDOI
Power Spectra for Cold Dark Matter and its Variants
TL;DR: In this paper, the authors present an accurate formula that describes the matter transfer functions of all common variants of the adiabatic cold dark matter model, including mixed dark matter models.
Journal ArticleDOI
Small scale cosmological perturbations: An Analytic approach
Wayne Hu,Naoshi Sugiyama +1 more
TL;DR: In this paper, the authors established general relations between the matter and cosmic microwave background (CMB) power spectra and their dependence on parameters on small scales through analytic techniques verified by numerical calculations, and determined the dependence of the respective acoustic amplitudes and damping lengths on fundamental cosmological parameters.
