Supernovae, Lensed CMB and Dark Energy
Wayne Hu, Dragan Huterer, Kendrick M. Smith
Supernova distance and primary CMB anisotropy measurements provide powerful probes of the dark energy evolution in a flat universe but degrade substantially once curvature is margi…
CMB Cluster Lensing: Cosmography with the Longest Lever Arm
Wayne Hu, Daniel E. Holz, Chris Vale
We discuss combining gravitational lensing of galaxies and the cosmic microwave background (CMB) by clusters to measure cosmographic distance ratios, and hence dark energy paramete…
Distortions in the Surface of Last Scattering
Peikai Li, Scott Dodelson, Wayne Hu
The surface of last scattering of the photons in the cosmic microwave background is not a spherical shell. Apart from its finite width, each photon experiences a different gravitat…
Spontaneous Isotropy Breaking: A Mechanism for CMB Multipole Alignments
Christopher Gordon, Wayne Hu, Dragan Huterer +1
We introduce a class of models in which statistical isotropy is broken spontaneously in the CMB by a non-linear response to long-wavelength fluctuations in a mediating field. These…
Lens covariance effects on likelihood analyses of CMB power spectra
Pavel Motloch, Wayne Hu
Non-Gaussian correlations induced in CMB power spectra by gravitational lensing must be included in likelihood analyses for future CMB experiments. We present a simple but accurate…
Bispectrum in Single-Field Inflation Beyond Slow-Roll
Peter Adshead, Wayne Hu, V Miranda
We develop an integral form for the bispectrum in general single-field inflation whose domain of validity includes models of inflation where the background evolution is not constra…
