Constraining Cut-off Physics in the Cosmic Microwave Background
Takemi Okamoto, Eugene A. Lim
We investigate the ability to constrain oscillatory features in the primordial power spectrum using current and future cosmic microwave background observations. In particular, we s…
Principal Power of the CMB
Wayne Hu, Takemi Okamoto
We study the physical limitations placed on CMB temperature and polarization measurements of the initial power spectrum by geometric projection, acoustic physics, gravitational len…
CMB Lensing Reconstruction on the Full Sky
Takemi Okamoto, Wayne Hu
Gravitational lensing of the microwave background by the intervening dark matter mainly arises from large-angle fluctuations in the projected gravitational potential and hence offe…
The Angular Trispectra of CMB Temperature and Polarization
Takemi Okamoto, Wayne Hu
We develop the formalism necessary to study four-point functions of the cosmic microwave background (CMB) temperature and polarization fields. We determine the general form of CMB…
Mass Reconstruction with CMB Polarization
Wayne Hu, Takemi Okamoto
Weak gravitational lensing by the intervening large-scale structure of the Universe induces high-order correlations in the cosmic microwave background (CMB) temperature and polariz…
