The advent of the second data release of the Gaia mission, in combination with data from
large spectroscopic surveys, is revolutionizing our understanding of the Galaxy. Thanks to …

Ever deeper and wider look-back surveys have led to a fairly robust outline of the cosmic
star-formation history, which culminated around; this period is often nicknamed “cosmic …

We report on the first search for nuclear recoils from dark matter in the form of weakly
interacting massive particles (WIMPs) with the XENONnT experiment, which is based on a …

The LUX-ZEPLIN experiment is a dark matter detector centered on a dual-phase xenon time
projection chamber operating at the Sanford Underground Research Facility in Lead, South …

The formation of our Milky Way can be split up qualitatively into different phases that resulted
in its structurally different stellar populations: the halo and the disk components,–. Revealing …

The ensemble of chemical element abundance measurements for stars, along with precision
distances and orbit properties, provides high-dimensional data to study the evolution of the …

We compile and analyze approximately 200 trigonometric parallaxes and proper motions of
molecular masers associated with very young high-mass stars. Most of the measurements …

We present a 0.16% precise and 0.27% accurate determination of R 0, the distance to the
Galactic center. Our measurement uses the star S2 on its 16-year orbit around the massive …

Abstract Our Milky Way should host an ancient, metal-poor, and centrally concentrated
stellar population, which reflects the star formation and enrichment in the few most massive …

The halo of the Milky Way provides a laboratory to study the properties of the shocked hot
gas that is predicted by models of galaxy formation. There is observational evidence of …
