Concepts in CMB Anisotropy Formation
Wayne Hu
These lecture notes form a primer on the theory of cosmic microwave background (CMB) anisotropy formation. With emphasis on conceptual aspects rather than technical issues, we exam…
Small Scale Cosmological Perturbations: An Analytic Approach
Wayne Hu, Naoshi Sugiyama
Through analytic techniques verified by numerical calculations, we establish general relations between the matter and cosmic microwave background (CMB) power spectra and their depe…
Wandering in the Background: A CMB Explorer
Wayne Hu
We develop and examine the principles governing the formation of distortions in the cosmic microwave background. Distortions in the frequency or spectral distribution of the backgr…
CMB Anisotropies in the Weak Coupling Limit
Wayne Hu, Martin White
We present a new, more powerful and accurate, analytic treatment of cosmic microwave background (CMB) anisotropies in the weakly coupled regime. Three applications are presented: g…
The Effect of Physical Assumptions on the Calculation of Microwave Background Anisotropies
Wayne Hu, Douglas Scott, Naoshi Sugiyama +1
As the data on CMB anisotropies improve and potential cosmological applications are realized, it will be increasingly important for theoretical calculations to be as accurate as po…
The Physics of Microwave Background Anisotropies
Wayne Hu, Naoshi Sugiyama, Joseph Silk
Cosmic microwave background anisotropies provide a vast amount of information on both structure formation in the universe and the background dynamics and geometry. The full physica…
