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…

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…

A Minkowski Functional Analysis of the Cosmic Microwave Background Weak Lensing Convergence
Jan Hamann, Yuqi Kang
Minkowski functionals are summary statistics that capture the geometric and morphological properties of fields. They are sensitive to all higher order correlations of the fields an…
