Constraining Galileon Inflation
Donough Regan, Gemma J. Anderson, Matthew Hull +1
In this short paper, we present constraints on the Galileon inflationary model from the CMB bispectrum. We employ a principal-component analysis of the independent degrees of freed…
Principal Components of CMB non-Gaussianity
Donough Regan, Dipak Munshi
The skew-spectrum statistic introduced by Munshi & Heavens (2010) has recently been used in studies of non-Gaussianity from diverse cosmological data sets including the detection o…
Optimal bispectrum constraints on single-field models of inflation
Gemma J. Anderson, Donough Regan, David Seery
We use WMAP 9-year bispectrum data to constrain the free parameters of an 'effective field theory' describing fluctuations in single-field inflation. The Lagrangian of the theory c…
