How Well Can Cosmological Parameters Be Estimated from CMB Observations?
J. Richard Bond, Richard L. Davis, Paul J. Steinhardt
The CMB anisotropy depends sensitively upon the slope and amplitude of primordial density and gravitational wave fluctuations, the baryon density, the Hubble constant, the cosmolog…
Measuring Cosmological Parameters with Cosmic Microwave Background Experiments
J. R. Bond, Robert Crittenden, Richard L. Davis +2
The cosmic microwave background anisotropy is sensitive to the slope and amplitude of primordial energy density and gravitational wave fluctuations, the baryon density, the Hubble…
Polarization of the Microwave Background due to Primordial Gravitational Waves
Robert Crittenden, Richard L. Davis, Paul J. Steinhardt
The contribution of gravitational wave (tensor metric) and energy density (scalar metric) fluctuations to the cosmic microwave background polarization is computed by numerically so…
The Imprint of Gravitational Waves on the Cosmic Microwave Background
R. Crittenden, J. R. Bond, R. L. Davis +2
Long-wavelength gravitational waves can induce significant temperature anisotropy in the cosmic microwave background. Distinguishing this from anisotropy induced by energy density…
Cauchy Horizons, Thermodynamics and Closed Time-like Curves in Planar Supersymmetric Space-times
M. Cvetič, R. Davis, S. Griffies +1
We study geodesically complete, singularity free space-times induced by supersymmetric planar domain walls interpolating between Minkowski and anti-de Sitter () vacua. A geo…
Cosmic Microwave Background Probes Models of Inflation
R. L. Davis, H. M. Hodges, G. F. Smoot +2
Inflation creates both scalar (density) and tensor (gravity wave) metric perturbations. We find that the tensor mode contribution to the CMB anisotropy on large-angular scales can…
