Measurement of helium isotopic composition in cosmic rays with AMS-02
… which is of particular interest to indirect dark matter searches. Helium-3, mainly a secondary cosmic ray species, is primarily produced by spallation of heavier cosmic rays, such as primary helium-4, with interstellar matter. In six years of data taking, AMS has collected the largest available …

Starbursts in extragalactic giant H II regions
… and the interplay between massive stars and the interstellar matter. For starbursts in giant H II regions, a key issue is whether a tight cluster is formed and later becomes a globular cluster or distributed OB associations are formed and later disperse. In addition, the types of environments …

Chemical gradients in the Milky Way from unsupervised chemical abundances measurements of the RAVE spectroscopic data set
… or that the thick disk formed from homogeneous interstellar matter. In particular, we found hundreds of stars which can be kinetically classified as thick disk stars exhibiting a chemical composition typical of the thin disk. A few stars of this kind have already been detected by other authors, …
