Computing High Accuracy Power Spectra with Pico
William A. Fendt, Benjamin D. Wandelt
This paper presents the second release of Pico (Parameters for the Impatient COsmologist). Pico is a general purpose machine learning code which we have applied to computing the CM…
Detection of primordial non-Gaussianity (fNL) in the WMAP 3-year data at above 99.5% confidence
Amit P. S. Yadav, Benjamin D. Wandelt
We present evidence for the detection of primordial non-Gaussianity of the local type (fNL), using the temperature information of the Cosmic Microwave Background (CMB) from the WMA…
Applications of Fast Convolution on the Sphere
K. M. Huffenberger, I. J. O'Dwyer, K. M. Gorski +1
We present several diverse applications of the spherical fast convolution method suggested by Wandelt and Gorski (2001), which is useful for studies of telescope optical properties…
Fast Estimator of Primordial Non-Gaussianity from Temperature and Polarization Anisotropies in the Cosmic Microwave Background
Amit P. S. Yadav, Eiichiro Komatsu, Benjamin D. Wandelt
Measurements of primordial non-Gaussianity () open a new window onto the physics of inflation. We describe a fast cubic (bispectrum) estimator of , using a combined…
21 cm radiation - a new probe of variation in the fine structure constant
Rishi Khatri, Benjamin D. Wandelt
We investigate the effect of variation in the value of the fine structure constant at high redshifts (recombination > z > 30) on the absorption of the cosmic microwave background (…
