Baryonic Features in the Matter Transfer Function
- D. Eisenstein, Wayne Hu
- Physics
- 12 September 1997
We provide scaling relations and fitting formulae for adiabatic cold dark matter cosmologies that account for all baryon effects in the matter transfer function to better than 10% in the large-scale…
Models of f(R) Cosmic Acceleration that Evade Solar-System Tests
- Wayne Hu, I. Sawicki
- Physics
- 8 May 2007
We study a class of metric-variation fRmodels that accelerates the expansion without a cosmological constant and satisfies both cosmological and solar-system tests in the small-field limit of the…
Power Spectra for Cold Dark Matter and Its Variants
- D. Eisenstein, Wayne Hu
- Physics
- 23 October 1997
The bulk of recent cosmological research has focused on the adiabatic cold dark matter model and its simple extensions. Here we present an accurate fitting formula that describes the matter transfer…
Small-Scale Cosmological Perturbations: An Analytic Approach
- Wayne Hu, N. Sugiyama
- Physics
- 23 October 1995
Through analytic techniques verified by numerical calculations, we establish general relations between the matter and cosmic microwave background (CMB) power spectra and their dependence on…
Report of the Dark Energy Task Force
- A. Albrecht, G. Bernstein, N. Suntzeff
- Physics, Education
- 1 September 2006
Dark energy appears to be the dominant component of the physical Universe, yet there is no persuasive theoretical explanation for its existence or magnitude. The acceleration of the Universe is,…
CMB-S4 Science Book, First Edition
- K. Abazajian, P. Adshead, W. L. K. Wu
- Physics
- 9 October 2016
This book lays out the scientific goals to be addressed by the next-generation ground-based cosmic microwave background experiment, CMB-S4, envisioned to consist of dedicated telescopes at the South…
Foregrounds and Forecasts for the Cosmic Microwave Background
- Max Tegmark, D. Eisenstein, Wayne Hu, A. D. Oliveira-Costa
- Physics
- 20 May 1999
One of the main challenges facing upcoming cosmic microwave background (CMB) experiments will be to distinguish the cosmological signal from foreground contamination. We present a comprehensive…
Weak lensing of the CMB: A harmonic approach
- Wayne Hu
- Physics
- 18 January 2000
Weak lensing of CMB anisotropies and polarization for the power spectra and higher order statistics can be handled directly in harmonic-space without recourse to real-space correlation functions. For…
Sample Variance Considerations for Cluster Surveys
- Wayne Hu, A. Kravtsov
- Physics
- 11 March 2002
We present a general statistical framework for describing the effect of sample variance in the number counts of virialized objects and examine its effect on cosmological parameter estimation.…
Cosmic Microwave Background Anisotropies
- Wayne Hu, S. Dodelson
- Physics
- 18 October 2001
▪ Abstract Cosmic microwave background (CMB) temperature anisotropies have and will continue to revolutionize our understanding of cosmology. The recent discovery of the previously predicted acoust...
