We present an atlas and follow-up spectroscopic observations of 87 thin stream-like
structures detected with the STREAMFINDER algorithm in Gaia DR3, of which 28 are new …

Context. Recent observational data show that the Milky Way galaxy contains about 170
globular clusters. A fraction of them is likely formed in dwarf galaxies that were accreted onto …

The dense environments in the cores of globular clusters (GCs) facilitate many strong
dynamical encounters among stellar objects. These encounters have been shown to be …

Context. After the second data release of Gaia, the number of new globular cluster
candidates has increased significantly. However, most of them need to be properly …

Dark matter subhalos that pass a thin tidal star stream change the velocities of the stars near
the point of closest encounter. Subsequent orbital evolution increases the stream width and …

This work presents the Globular cluster Extra-tidal Mock Star (GEMS) catalogue of extra-tidal
stars and binaries created via three-body dynamical encounters in globular cluster cores …

The innermost parts of the Milky Way (MW) are very difficult to observe due to the high
extinction along the line of sight, especially close to the disc mid-plane. However, this region …

The stellar disc is the dominant luminous component of the Milky Way (MW). Although our
understanding of its structure is rapidly expanding due to advances in large-scale stellar …

Context. Unresolved binaries have a strong influence on the observed parameters of stellar
clusters (SCs). Aims. We quantify this influence and compute the resulting mass …

We present results of the analysis of a set of images obtained in the field of the Milky Way
bulge globular cluster NGC 6355 using the Dark Energy Camera, which is attached to the 4 …
