All-sky Kinematics and Chemistry of Monoceros Stellar Overdensity
Lais Borbolato, Hélio D. Perottoni, Silvia Rossi +7
We explore the kinematic and chemical properties of Monoceros stellar overdensity by combining data from 2MASS, WISE, APOGEE, and . Monoceros is a structure located to…
The Chemodynamical Nature of the Triangulum-Andromeda Overdensity
Yuri Abuchaim, Hélio D. Perottoni, Silvia Rossi +7
We present a chemodynamical study of the Triangulum-Andromeda overdensity (TriAnd) employing a sample of 31 candidate stars observed with the GRACES high-resolution (=40,000) sp…
Reconstructing the Disrupted Dwarf Galaxy -Sausage/Enceladus Using its Stars and Globular Clusters
Guilherme Limberg, Stefano O. Souza, Angeles Pérez-Villegas +3
We combine spectroscopic, photometric, and astrometric information from APOGEE data release 17 and early data release 3 to perform a self-consistent characterization of $Gai…
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…
The Case for Electron Re-Acceleration at Galaxy Cluster Shocks
Reinout J. van Weeren, Felipe Andrade-Santos, William A. Dawson +16
On the largest scales, the Universe consists of voids and filaments making up the cosmic web. Galaxy clusters are located at the knots in this web, at the intersection of filaments…
The age structure of the Milky Way's halo
D. Carollo, T. C. Beers, V. M. Placco +7
We present a new, high-resolution chronographic (age) map of the Milky Way's halo, based on the inferred ages of ~130,000 field blue horizontal-branch (BHB) stars with photometry f…
