Star clusters across cosmic time
Star clusters stand at the intersection of much of modern astrophysics: the ISM, gravitational
dynamics, stellar evolution, and cosmology. Here, we review observations and theoretical …

No massive black holes in the Milky Way halo
P Mróz, A Udalski, MK Szymański, I Soszyński… - Nature, 2024 - nature.com
The gravitational wave detectors have shown a population of massive black holes that do
not resemble those observed in the Milky Way,–and whose origin is debated,–. According to …

The merger that led to the formation of the Milky Way's inner stellar halo and thick disk
The assembly of our Galaxy can be reconstructed using the motions and chemistry of
individual stars1, 2. Chemo-dynamical studies of the stellar halo near the Sun have …
