Context. The position of the Sun inside the disc of the Milky Way significantly hampers the study of the spiral arm structure given the high amount of dust and gas along the line of sight, and the overall structure of this disc has therefore not yet been fully characterised. Aims. We aim to analyse the spiral arms in the line of sight towards the Galactic centre (GC) in order to determine their distance, extinction, and stellar population. Methods. We use the GALACTICNUCLEUS survey, a JHKs high…

Detection of an excess of young stars in the Galactic Centre Sagittarius B1 region

The Milky Way’s centre is the closest galaxy nucleus and the most extreme environment in the Galaxy. Although its volume is less than 1% of that of the Galactic Disk, up to 10% of all new stars in

Stochastic nature of Galactic cosmic-ray sources

The precision measurements of the spectra of cosmic ray nuclei and leptons in recent years have revealed the existence of multiple features, such as the spectral break at ∼ 300 GV rigidity seen by
