Multi-Scale Perturbation Theory II: Solutions and Leading-Order Bispectrum in the CDM Universe
Christopher S. Gallagher, Timothy Clifton, Chris Clarkson
Two-parameter perturbation theory (2PPT) is a framework designed to include the relativistic gravitational effects of small-scale nonlinear structures on the large-scale properties…
Viable Gauge Choices in Cosmologies with Non-Linear Structures
Timothy Clifton, Christopher S. Gallagher, Sophia Goldberg +1
A variety of gauges are used in cosmological perturbation theory. These are often chosen in order to attribute physical properties to a particular choice of coordinates, or otherwi…
Multi-Scale Perturbation Theory I: Methodology and Leading-Order Bispectrum Corrections in the Matter-Dominated Era
Christopher Gallagher, Timothy Clifton, Chris Clarkson
Two-parameter perturbation theory is a scheme tailor-made to consistently include nonlinear density contrasts on small scales (), whilst retaining a traditiona…
Relativistic Euler Equations in cosmologies with non-linear structures
Christopher S. Gallagher, Timothy Clifton
We consider a new variant of cosmological perturbation theory that has been designed specifically to include non-linear density contrasts on scales 100 Mpc, while still allowing fo…
Perturbation theory for cosmologies with non-linear structure
Sophia R. Goldberg, Christopher Gallagher, Timothy Clifton
The next generation of cosmological surveys will operate over unprecedented scales, and will therefore provide exciting new opportunities for testing general relativity. The standa…
