Generative adversarial networks (GANs) have been recently applied as a novel emulation technique for large-scale structure simulations. Recent results show that GANs can be used as a fast and efficient emulator for producing novel weak lensing convergence maps as well as cosmic web data in 2D and 3D. However, like any algorithm, the GAN approach comes with a set of limitations, such as an unstable training procedure, inherent randomness of the produced outputs, and difficulties when training… 

Emulation of Cosmological Mass Maps with Conditional Generative Adversarial Networks

A novel conditional GAN model is proposed that is able to generate mass maps for any pair of matter density Ω m and matter clustering strength σ 8, parameters which have the largest impact on the evolution of structures in the Universe, for a given source galaxy redshift distribution n(z).

Can denoising diffusion probabilistic models generate realistic astrophysical fields?

This work investigates the ability of score-based generative models to generate dark matter mass density from cosmological simulations and images of interstellar dust in two astrophysical contexts, and demon-strate a proof-of-concept application of the model trained on dust in denoising dust images.

Cosmological N-body simulations: a challenge for scalable generative models

A scalable GAN approach for training a generator of N-body three-dimensional cubes, which relies on splitting the generation of the high-dimensional data into smaller parts, and using a multi-scale approach that efficiently captures global image features that might otherwise be lost in the splitting process.
