Background: Primary care level close monitoring of mild COVID-19 patients has shown to
provide a risk reduction in hospitalization and death. We aimed to compare the risk of all-…

We combine spectroscopic, photometric, and astrometric information from APOGEE data
release 17 and Gaia early data release 3 to perform a self-consistent characterization of Gaia-…

We analyze the dynamical properties of∼ 1500 very metal-poor (VMP;[Fe/H]≲− 2.0) halo
stars, based primarily on medium-resolution spectroscopic data from the HK and Hamburg/…

The Multivariate Exploratory Data Analysis (MEDA) Toolbox in Matlab is a set of multivariate
analysis tools for the exploration of data sets. In the MEDA Toolbox, traditional exploratory …

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 …

Es indudable que nos encontramos a las puertas, cuando no ya en los comienzos, de una
transformación mundial sin precedentes y comparable con la sobrevenida a lo largo del siglo …

We identified eight additional stars as members of the Helmi stream (HStr) in the combined
GALAH+ DR3 and Gaia EDR3 catalog. By consistently reevaluating claimed members from …

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

We present a chemodynamical study of the Triangulum–Andromeda overdensity (TriAnd)
employing a sample of 31 candidate stars observed with the GRACES high-resolution (R= …
