Satellites of satellites: the power of combining HST photometry and Gaia

, 2019
In the prevailing Lambda Cold Dark Matter cosmology, galaxies grow continuously in mass through hierarchical assembly of smaller systems, and dark matter halos host substructures down to the resolution limit of the simulations. Hierarchical evolution should occur at all scales, implying that the satellites of the Milky Way should also have companions ...

Star Clusters in the Near-ultraviolet-optical-near-infrared: Spectral Energy Distribution Modeling with Direct Markers of Gas and Dust Emission

The Astrophysical Journal
The large number of star clusters in nearby galaxies permits us to statistically test the predictions of stellar, dust, and gas models. Using Hubble Space Telescope (HST) broadband plus H α imaging combined with JWST near-infrared imaging, we use a total

oMEGACat. II. Photometry and Proper Motions for 1.4 Million Stars in Omega Centauri and Its Rotation in the Plane of the Sky

The Astrophysical Journal
Omega Centauri ( ω Cen) is the most massive globular cluster of the Milky Way. It is thought to be the nucleus of an accreted dwarf galaxy because of its high mass and its complex stellar populations.
