Constraining the WMAP9 bispectrum and trispectrum with needlets
Donough Regan, Mateja Gosenca, David Seery
We develop a needlet approach to estimate the amplitude of general (including non-separable) bispectra and trispectra in the cosmic microwave background, and apply this to the WMAP…
The δN formula is the dynamical renormalization group
Mafalda Dias, Raquel H. Ribeiro, David Seery
We derive the 'separate universe' method for the inflationary bispectrum, beginning directly from a field-theory calculation. We work to tree-level in quantum effects but to all or…
Moment transport equations for non-Gaussianity
David J. Mulryne, David Seery, Daniel Wesley
We present a novel method for calculating the primordial non-Gaussianity produced by super-horizon evolution during inflation. Our method evolves the distribution of coarse-grained…
