Algorithms for bispectra: forecasting, optimal analysis, and simulation
Kendrick M. Smith, Matias Zaldarriaga
We propose a factorizability ansatz for angular bispectra which permits fast algorithms for forecasting, analysis, and simulation, yet is general enough to encompass many interesti…
A general solution to the E-B mixing problem
Kendrick M. Smith, Matias Zaldarriaga
We derive a general ansatz for optimizing pseudo-C_l estimators used to measure CMB anisotropy power spectra, and apply it to the recently-proposed pure pseudo-C_l formalism, to ob…
Pure pseudo-C_l estimators for CMB B-modes
Kendrick M. Smith
Fast heuristically weighted, or pseudo-C_l, estimators are a frequently used method for estimating power spectra in CMB surveys with large numbers of pixels. Recently, Challinor &…
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…
Cosmological Information from Lensed CMB Power Spectra
Kendrick M. Smith, Wayne Hu, Manoj Kaplinghat
Gravitational lensing distorts the cosmic microwave background (CMB) temperature and polarization fields and encodes valuable information on distances and growth rates at intermedi…
