Satellite abundance in Milky Way-like halos plays a crucial role in distinguishing dark matter models, in particular, in dark matter models where a suppression of substructure is expected below a mass scale. One model that has gained recent interest is the Quantum/Fuzzy or Wave Dark Matter model, where the dark...

The Lyman-alpha emission line offers a powerful window into galaxies and their diffuse environments at high redshift. Observations from high-sensitivity instruments mounted on telescopes such as Subaru, HET, and JWST encode the distribution of hydrogen and the processes shaping its evolution. However, interpreting these data remains challenging due to the...
