Cosmological Perturbations: Vorticity, Isocurvature and Magnetic Fields
Adam J. Christopherson
In this paper I review some recent, interlinked, work undertaken using cosmological perturbation theory -- a powerful technique for modelling inhomogeneities in the Universe. The c…

A short note on the curvature perturbation at second order
Adam J. Christopherson, Ellie Nalson, Karim A. Malik
Working with perturbations about an FLRW spacetime, we compute the gauge-invariant curvature perturbation to second order solely in terms of scalar field fluctuations. Using the cu…
