Applications of Cosmological Perturbation Theory
Adam J. Christopherson
Cosmological perturbation theory is crucial for our understanding of the universe. The linear theory has been well understood for some time, however developing and applying the the…

Can cosmological perturbations produce early universe vorticity?
Adam J. Christopherson, Karim A. Malik
In this special issue article, based on the talk with the same title in session B5 (Theoretical and Mathematical Cosmology) at GR19, we review the case of vorticity generation in c…

Estimating the amount of vorticity generated by cosmological perturbations in the early universe
Adam J. Christopherson, Karim A. Malik, David R. Matravers
We estimate the amount of vorticity generated at second order in cosmological perturbation theory from the coupling between first order energy density and non-adiabatic pressure, o…
