Predicting the final states of binary-single scattering with machine learning
Ahmad Farhani Asl, David Fonseca Mota, Dennis Fremstad +1
Context. Binary-single encounters are particularly frequent in dense stellar environments, where they play a central role in shaping the dynamical evolution of their host systems.…

Separate Universe Super-Resolution Emulator
Dennis Fremstad, Julian Adamek, David F. Mota
We present a machine-learning model for generating super-resolution -body simulations with non-vanishing spatial curvature, conditioned on a given low-resolution field, ,…

Emulating the Non-Linear Matter Power-Spectrum in Mixed Axion Dark Matter Models
Dennis Fremstad, Hans A. Winther
In order to constrain ultra light dark matter models with current and near future weak lensing surveys we need the predictions for the non-linear dark matter power-spectrum. This i…
