Repository for extended dark matter object constraints (2025)
Journal Article
Croon, D., & Sevillano Muñoz, S. (2025). Repository for extended dark matter object constraints. The European Physical Journal C, 85(1), Article 8. https://doi.org/10.1140/epjc/s10052-024-13681-x

Extended dark matter objects (EDOs) are popular dark matter candidates that interact gravitationally with the Standard Model. These gravitational interactions can be used to constrain their allowed parameter space. However, EDOs can have different fo...

In this study, we examine the role of the circumgalactic medium (CGM) angular momentum (jCGM) on star formation in galaxies, whose influence is currently not well understood. The analysis utilises central galaxies from two hydrodynamical simulations,... Read More about Disparate effects of circumgalactic medium angular momentum in IllustrisTNG and SIMBA.

The Astrophysical Journal, 978(2), Article 129. https://doi.org/10.3847/1538-4357/ad99d6

Interpretation of data from faint dwarf galaxies is made challenging by observations limited to only the brightest stars. We present a major improvement to tackle this challenge by undertaking zoomed cosmological simulations that resolve the evolutio...
