Synthetic JWST galaxy images in the TNG50 simulation - I. Model validation and comparison to observations
Alejandro Guzmán-Ortega, Gustavo Bruzual, Vicente Rodriguez-Gomez +1
We use the TNG50 cosmological simulation and three-dimensional radiative transfer post-processing to generate dust-aware synthetic observations of galaxies at a…

A Physically Motivated Framework to Compare Merger Timescales of Isolated Low- and High-Mass Galaxy Pairs Across Cosmic Time
Katie Chamberlain, Ekta Patel, Gurtina Besla +2
The merger timescales of isolated low-mass pairs () on cosmologically motivated orbits have not yet been studied in detail, though isolated hig…

ERGO-ML: Comparing IllustrisTNG and HSC galaxy images via contrastive learning
Lukas Eisert, Connor Bottrell, Annalisa Pillepich +5
Modern cosmological hydrodynamical galaxy simulations provide tens of thousands of reasonably realistic synthetic galaxies across cosmic time. However, quantitatively assessing the…
