TUNeS: Neural Emulation of Large-Scale Structure Across Redshifts
Yuqi Kang, Hu Bin, Dongxing Li +1
In this work, we introduce TUNeS (Temporal UNet emulator for Structure formation), a neural network framework for accelerating N-body simulations by predicting the nonlinear evolut…

Bayesian optimisation for Bayesian evidence (BOBE) -- a fast and efficient likelihood emulator for model selection
Nathan Cohen, Jan Hamann, Ameek Malhotra
The formalism of Bayesian model selection provides a very elegant way of ranking different physical models in terms of how compatible they are with a given set of observed data. Ho…

Non-Gaussianity in CMB lensing from full-sky simulations
Jan Hamann, Yuqi Kang
The lensing convergence field describing the weak lensing effect of the Cosmic Microwave Background (CMB) radiation is expected to be subject to mild deviations from Gaussianity. W…
