Phase-space Properties and Chemistry of the Sagittarius Stellar Stream Down to the Extremely Metal-poor () Regime

Guilherme Limberg, Anna B. A. Queiroz, Hélio D. Perottoni +6

In this work, we study the phase-space and chemical properties of Sagittarius (Sgr) stream, the tidal tails produced by the ongoing destruction of Sgr dwarf spheroidal (dSph) galax…

The Unmixed Debris of Gaia-Sausage/Enceladus in the Form of a Pair of Halo Stellar Overdensities

Hélio D. Perottoni, Guilherme Limberg, João A. S. Amarante +5

In the first billion years after its formation, the Galaxy underwent several mergers with dwarf satellites of various masses. The debris of Gaia-Sausage/Enceladus (GSE), the galaxy…
