Evidence for multiple crossings and stripping of Gaia-Enceladus/Sausage across the Milky Way
Astronomy & AstrophysicsContext. The accretion of Gaia-Enceladus/Sausage (GES) onto the Milky Way (MW) is one of the most prominent features of the Galactic halo revealed by the combination of the Gaia satellite and large spectroscopic surveys.

Subsystems of the Galactic halo, their structures and compositions
Odessa Astronomical Publications, 2017 It is shown that general populations of globular clusters and metal-poor field stars are components at least of three subsystems occupying different volumes in the Galaxy.

Element Abundances at High Redshifts: The N/O Ratio in a Primeval Galaxy [PDF]
, 1995 The damped Lyman alpha systems seen in the spectra of high redshift QSOs offer the means to determine element abundances in galaxies observed while still at an early stage of evolution.

Abundance gradients and galaxy formation
The Astrophysical Journal, 1991 A three-dimensional collisionless code is used to simulate the formation of elliptical galaxies with a time scale for star formation comparable to the collapse time. A one-zone chemical evolution scheme is used to compute the evolution of the abundances of several chemical elements.

People and Nature, EarlyView.Abstract In Central Africa, human activities are severely impacting terrestrial and aquatic wildlife, threatening the food security of millions of people. Accordingly, sustainable use of wildlife is crucial for the nutrition and livelihoods of many rural communities in the region.

First Stellar Abundances in the Dwarf Irregular Galaxy Sextans A [PDF]
, 2004 We present the abundance analyses of three isolated A-type supergiant stars in the dwarf irregular galaxy Sextans A (=DDO 75) from high-resolution spectra obtained with the Ultraviolet-Visual Echelle Spectrograph (UVES) on the Kueyen telescope (UT2) of ...

Wildlife Biology, EarlyView.Roe deer is a species that hides their neonates as an anti‐predator strategy. This may prove efficient against mammalian predators, such as the red fox; however, it might be an ecological trap as large numbers of fawns are killed by tractors with harvesters each year during grass harvest.

Chemical analysis of the Milky Way’s nuclear star cluster
Astronomy & AstrophysicsContext. The Milky Way nuclear star cluster (MWNSC) is located in the Galactic centre, together with the Milky Way nuclear stellar disc (MWNSD), and they dominate the gravitational potential within the inner 300 pc.
