Galaxy archaeology through the synergy of Subaru and space telescopes

Sakurako Okamoto

Over the last two decades, wide-field resolved star studies have shown a remarkable variety of stellar (sub-)structures in the halos of the Milky Way and M31, attesting to the fact that accretions have played an essential role in shaping their evolution. Pushing these studies to galaxy systems beyond the Local...

Probing the quantum-like nature of the dark matter using observations of dwarf galaxies in our Milky Way and Local Group

Victor Robles

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...

Mapping the High-Redshift Universe Across Scales with the Lyman-alpha line

Chris Byrohl

Heidelberg University

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...
