Quantum initial conditions for curved inflating universes
Mary I. Letey, Zakhar Shumaylov, Fruzsina J. Agocs +3
We discuss the challenges of motivating, constructing, and quantizing a canonically normalized inflationary perturbation in spatially curved universes. We show that this has histor…
Conformally-rescaled Schwarzschild metrics do not predict flat galaxy rotation curves
Michael Hobson, Anthony Lasenby
For conformally invariant gravity theories defined on Riemannian spacetime and having the Schwarzschild--de-Sitter (SdS) metric as a solution in the Einstein gauge, we consider whe…
Nested sampling for physical scientists
Greg Ashton, Noam Bernstein, Johannes Buchner +20
We review Skilling's nested sampling (NS) algorithm for Bayesian inference and more broadly multi-dimensional integration. After recapitulating the principles of NS, we survey deve…
Split personalities in Bayesian Neural Networks: the case for full marginalisation
David Yallup, Will Handley, Mike Hobson +2
The true posterior distribution of a Bayesian neural network is massively multimodal. Whilst most of these modes are functionally equivalent, we demonstrate that there remains a le…
Finite inflation in curved space
Lukas T. Hergt, Fruzsina J. Agocs, Will J. Handley +2
We investigate the effects of non-zero spatial curvature on cosmic inflation in the light of cosmic microwave background (CMB) anisotropy measurements from the Planck 2018 legacy r…
Note on the absence of the second clock effect in Weyl gauge theories of gravity
Michael Hobson, Anthony Lasenby
We reconsider the status of the so-called second clock effect in Weyl gauge theories of gravity, which are invariant both under local Poincaré transformations and local changes of…
