Exact solution to perturbative conformal cosmology from recombination until the current era
Asanka Amarasinghe, Tianye Liu, Daniel A. Norman +1
In a previous paper (P. D. Mannheim, Phys. Rev. D 102, 123535 (2020)) we studied cosmological perturbation theory in the cosmology associated with the fourth-order derivative confo…
Cosmological Fluctuations on the Light Cone
Asanka Amarasinghe, Philip D. Mannheim
In studying temperature fluctuations in the cosmic microwave background Weinberg has noted that some ease of calculation and insight can be achieved by looking at the structure of…
Three-dimensional and four-dimensional scalar, vector, tensor cosmological fluctuations and the cosmological decomposition theorem
Matthew G. Phelps, Asanka Amarasinghe, Philip D. Mannheim
In cosmological perturbation theory it is convenient to use the scalar, vector, tensor (SVT) basis as defined according to how these components transform under 3-dimensional rotati…
Cosmological perturbations in conformal gravity II
Asanka Amarasinghe, Matthew G. Phelps, Philip D. Mannheim
In this paper we continue a study of cosmological perturbations in the conformal gravity theory. In previous work we had obtained a restricted set of solutions to the cosmological…
