It is now well established that globular clusters (GCs) host multiple stellar populations with distinct chemical compositions. However, the formation mechanisms responsible for the unique abundance patterns observed in these systems remain a major unresolved problem in stellar astrophysics. Although multiple populations are found in the majority of studied old and massive GCs, their incidence...

In the ΛCDM cosmological framework, dark matter (DM) halos represent the building blocks for galactic structures. Galaxies are expected to form stars from their gas reservoirs in the gravitational potential of these DM halos, which are predicted to be more common with decreasing mass. But not all DM halos effectively convert this gas into stars, forming a galaxy. Gas may accumulate without...

The ΛCDM model successfully describes the hierarchical large-scale structure of the Universe, but it also predicts a much larger number of low-mass dark matter haloes than are actually observed. This tension can be explained by the fact that below a certain mass threshold, star formation is suppressed. However, these low-mass haloes should contain a significant amount of HI, which could be...
