Evidence for the Typhon Stellar Stream as the Remnant of a Recently-disrupted Dwarf Galaxy
João V. Nogueira-Santos, Guilherme Limberg, Silvia Rossi +4
In the hierarchical model of galaxy formation, the Milky Way's stellar halo assembles through the successive accretion of dwarf galaxies. While many resulting substructures have be…

Characterizing the velocity anisotropy of the Milky Way's stellar halo
F. O. Barbosa, A. Pérez-Villegas, S. Rossi +6
Modeling the Milky Way stellar halo requires well-determined density and velocity anisotropy profiles. However, it has been challenging to gather a large sample of stars with six-d…

Early Co-formation of the Milky Way's Thin and Thick Disks at Redshift z > 2
Lais Borbolato, Silvia Rossi, Hélio D. Perottoni +8
The Milky Way serves as a template for understanding the formation and evolution of late-type massive disk galaxies since we can obtain detailed chemical and kinematic information…
