The growing availability of observational data on the small‑scale structure of the Universe offers an exciting opportunity to move beyond average scaling relations and study the diverse population of low surface brightness galaxies in greater detail. Analyzing large samples of these galaxies, including dwarf galaxies, across different environments is no small task. It requires both large simulated cosmological volumes (wide survey coverage) and high resolution (deep surface brightness sensitivity), a combination that is challenging computationally (observationally). Dwarf galaxies are expected to be particularly sensitive probes for testing various dark matter (DM) models. In simulations, their properties are influenced both by unresolved baryonic processes, such as stellar feedback, and by variations in the assumed DM model. It is therefore crucial to carefully model baryonic processes and interpret the results from simulations with caution. A wealth of new data on the low‑surface brightness Universe is expected within the next years, but detailed simulation data and robust new analysis techniques are critical to use the exciting new data on the visible matter for a better understanding of the DM content of the Universe.
