Learning from Topology: Cosmological Parameter Estimation from the Large-scale Structure
Jacky H. T. Yip, Adam Rouhiainen, Gary Shiu
The topology of the large-scale structure of the universe contains valuable information on the underlying cosmological parameters. While persistent homology can extract this topolo…
Late-time attractors and cosmic acceleration
Gary Shiu, Flavio Tonioni, Hung V. Tran
We prove the conditions under which scaling cosmologies are inevitable late-time attractors of multi-field multi-exponential potentials, independently of initial conditions. The ad…
Accelerating universe at the end of time
Gary Shiu, Flavio Tonioni, Hung V. Tran
We investigate whether an accelerating universe can be realized as an asymptotic late-time solution of FLRW-cosmology with multi-field multi-exponential potentials. Late-time cosmo…
A 10d construction of Euclidean axion wormholes in flat and AdS space
Gregory J. Loges, Gary Shiu, Thomas Van Riet
Euclidean wormhole geometries sourced by axions and dilatons are puzzling objects in quantum gravity. From one side of the wormhole to the other, the scalar fields traverse a few P…
