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 S-PLUS Fifth Data-Release: Over 4500 square degrees of the Southern Sky and a multicolor view of the Hydra and Antlia galaxy clusters
Erik Vinicius Rodrigues de Lima, Gustavo Bernhard Oliveira Schwarz, Fábio Rafael Herpich +55
We present the 5th data release (DR5) of the Southern Photometric Local Universe Survey (S-PLUS), covering 4592 square degrees across 2491 fields. Observations were conducted with…
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…
Scientific Validation of the SPARC4 Pipeline: Multi-band Imaging, Polarimetry, and Photometric Time Series for Improved Characterization of Transiting Exoplanets
Eder Martioli, Claudia V. Rodrigues, Julio C. N. Campagnolo +14
High-cadence multi-band imaging and polarimetry have important scientific applications in astronomy. Observations of transits of exoplanets are a particular application that requir…
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…
