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…
The Low- Splash Population in the Milky Way
Lais Borbolato, João A. S. Amarante, Hélio D. Perottoni +5
The Milky Way in-situ halo, also known as the Splash, consists of old (age 10 Gyr), metal-rich ([Fe/H] ), high- stars, i.e., thick disk-like chemistry, on halo-like…
The Metallicity Gradient of Sagittarius Dwarf Spheroidal Galaxy Prior to Infall Constrained by S-PLUS Observations of its Tidal Stream
Felipe Almeida-Fernandes, Guilherme Limberg, Hélio D. Perottoni +16
We study the metallicity distribution along the Sagittarius (Sgr) stream using photometric metallicities from S-PLUS DR4, combined with Gaia DR3 kinematics and APOGEE DR17 spectros…
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…
S-PLUS: Beyond Spectroscopy IV. Stellar Parameters and Elemental-abundance Ratios for Six Million Stars from DR4 and First Results for the Magellanic Clouds
Yang Huang, Timothy C. Beers, Kai Xiao +18
We combine narrow/medium-band filter photometry from the Southern Photometric Local Universe Survey (S-PLUS) DR4 with ultra broad-band filter photometry from Gaia EDR3 to derive fu…
Investigating the role of mergers in galaxy assembly in the early Universe (z > 5)
A. Calabrò, L. Pentericci, M. Llerena +20
Galaxy mergers play a crucial role in shaping the morphology, the star formation, and the mass growth of galaxies across cosmic time. While mergers have been extensively investigat…
