Context. The spatial distribution of elemental abundances and their time evolution are
among the major constraints to disentangling the scenarios of formation and evolution of the …

Aims. In this paper we derive the structure of the Galactic stellar warp and flare. Methods. We
use 2MASS red clump and red giant stars, selected at mean and fixed heliocentric distances …

We have pursued two different methods to analyze the old stellar population near the
Galactic plane, using data from the 2MASS survey. The first method is based on the isolation …

Abstract We present 0 farcs 075 (≈ 400 pc) resolution Atacama Large Millimeter/
submillimeter Array (ALMA) observations of the [C ii] and dust continuum emission from the …

Recent studies have revealed an oscillating asymmetry in the vertical structure of the Milky
Way's disc. Here, we analyse 16 high-resolution, fully cosmological simulations of the …

We present 21-cm HI line and optical R-band observations for a sample of 26 edge-on
galaxies. The HI observations were obtained with the Westerbork Synthesis Radio …

We have undertaken an 21-cm line survey of 472 late-type, edge-on spiral galaxies using
the NançayRadio Telescope and the Green Bank 140-Foot Telescope. Our targets consisted …

We present a detailed analysis of a disc galaxy forming in a high-resolution fully
cosmological simulation to investigate the nature of the outer regions of discs and their …

Seven cosmological hydrodynamic simulations of disk galaxy formation are analyzed to
determine the alignment of the disk within the dark matter halo and the internal structure of …

The warp is a well-known undulation of the Milky Way disc. Its structure has been widely
studied, but only since Gaia DR2 has it been possible to reveal its kinematic signature …
