Generating the cosmic microwave background power asymmetry with gNL
Published in PRD
In this paper we obtain a try to explain the observed CMB asymmetry using a higher order term in a Taylor series.

The squeezed limit of the bispectrum in multi-field inflation
Published in JCAP
In this paper we study the non-Gaussian nature of cosmological perturbations by calculating the squeezed limit of the bispectrum produced by inflation with multiple light fields.
