Influence of large local and non-local bispectra on primordial black hole abundance
Sam Young, Donough Regan, Christian T. Byrnes
Primordial black holes represent a unique probe to constrain the early universe on small scales - providing the only constraints on the primordial power spectrum on the majority of…
The hemispherical asymmetry from a scale-dependent inflationary bispectrum
Christian T. Byrnes, Donough Regan, David Seery +1
If the primordial bispectrum is sufficiently large then the CMB hemispherical asymmetry may be explained by a large-scale mode of exceptional amplitude which perturbs the zeta two-…
The bispectrum of cosmic string temperature fluctuations including recombination effects
Donough Regan, Mark Hindmarsh
We calculate the cosmic microwave background temperature bispectrum from cosmic strings, for the first time including the contributions from the last scattering surface, using a we…
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…
