The sounds of science a symphony for many instruments and voices part II
Gerard t Hooft, William D Phillips, Anton Zeilinger +22
Despite its amazing quantitative successes and contributions to revolutionary technologies, physics currently faces many unsolved mysteries ranging from the meaning of quantum mech…
Canada and the SKA from 2020-2030
Kristine Spekkens, Cynthia Chiang, Roland Kothes +57
This white paper submitted for the 2020 Canadian Long-Range Planning process (LRP2020) presents the prospects for Canada and the Square Kilometre Array (SKA) from 2020-2030, focuss…
Data Analysis and Phenomenological Cosmology
Alan A. Coley, Beethoven Santos, Viraj A A Sanghai
In the era of precision cosmology, even percentage level effects are significant on cosmological observables. The recent tension between the local and global values of is muc…
Parametrizing theories of gravity on large and small scales in cosmology
Timothy Clifton, Viraj A. A. Sanghai
We present a link between parametrizations of alternative theories of gravity on large and small scales in cosmology. This relationship is established using theoretical consistency…
Post-Newtonian Gravity in Cosmology
Viraj A. A. Sanghai
The post-Newtonian (PN) perturbative framework has been successful in understanding the slow-motion, weak field limit of Einstein's theory of gravity on solar system scales, and fo…
Ray tracing and Hubble diagrams in post-Newtonian cosmology
Viraj A. A. Sanghai, Pierre Fleury, Timothy Clifton
On small scales the observable Universe is highly inhomogeneous, with galaxies and clusters forming a complex web of voids and filaments. The optical properties of such configurati…
Parameterized Post-Newtonian Cosmology
Viraj A. A. Sanghai, Timothy Clifton
Einstein's theory of gravity has been extensively tested on solar system scales, and for isolated astrophysical systems, using the perturbative framework known as the parameterized…
Cosmological backreaction in the presence of radiation and a cosmological constant
Viraj A. A. Sanghai, Timothy Clifton
We construct high-precision models of the Universe that contain radiation, a cosmological constant, and periodically distributed inhomogeneous matter. The density contrasts in thes…
Post-Newtonian cosmological models
Viraj A. A. Sanghai
We construct a framework to probe the effect of non-linear structure formation on the large-scale expansion of the universe. We take a bottom-up approach to cosmological modelling…
Post-Newtonian Cosmological Modelling
Viraj A. A. Sanghai, Timothy Clifton
We develop a new approach to building cosmological models, in which small pieces of perturbed Minkowski space are joined together at reflection-symmetric boundaries in order to for…
