Covariant Linear Perturbation Formalism
Wayne Hu
Lecture notes on covariant linear perturbation theory and its applications to inflation, dark energy or matter and the cosmic microwave background.
CMB Anisotropies: A Decadal Survey
Wayne Hu
We review the theoretical implications of the past decade of CMB anisotropy measurements, which culminated in the recent detection of the first feature in the power spectrum, and d…
Cosmic complementarity: probing the acceleration of the Universe
Max Tegmark, Daniel J. Eisenstein, Wayne Hu +1
We assess the accuracy with which Omega and Lambda can be measured by combining various types of upcoming experiments. Useful expressions for the Fisher information matrix are deri…
Cosmic complementarity: combining CMB and supernova observations
Max Tegmark, Daniel J. Eisenstein, Wayne Hu
We compute the accuracy with which Omega and Lambda can be measured by combining future SN Ia and CMB experiments, deriving a handy expression for the SN Ia Fisher information matr…
Measuring the Curvature of the Universe
Wayne Hu, Martin White
We discuss how the curvature of the universe can be robustly measured employing only the gross features of the CMB anisotropy spectrum. Though the position of the first peak is not…
Testing Inflation with Small Scale CMB Anisotropies
Martin White, Wayne Hu
We discuss ability of the harmonic pattern of peaks in the CMB angular power spectrum to test inflation. By studying robust features of alternate models, which must all be isocurva…
