Planck Trispectrum Constraints on Primordial Non-Gaussianity at Cubic Order
Chang Feng, Asantha Cooray, Joseph Smidt +3
Non-Gaussianity of the primordial density perturbations provides an important measure to constrain models of inflation. At cubic order the non-Gaussianity is captured by two parame…

Constraints on Spatial Variations in the Fine-Structure constant from Planck
Jon O'Bryan, Joseph Smidt, Francesco De Bernardis +1
We use the Cosmic Microwave Background (CMB) anisotropy data from Planck to constrain the spatial fluctuations of the fine-structure constant α. Through Thompson scattering of CMB…
