DOI: 10.1038/s41586-025-08783-9
Abstract: Nuclear star clusters (NSCs) are the densest stellar systems in the Universe. These clusters can be found at the centre of all galaxy types but tend to favour galaxies of intermediate stellar mass around 109M⊙… read more here.

DOI: 10.1088/1674-4527/acd58d
Abstract: Open clusters (OCs) are infrequent survivors of embedded clusters gestated in molecular clouds. Up to now, little is known about the initial conditions for the formation of OCs. Here, we studied this issue using high-precision… read more here.

DOI: 10.1093/mnras/staa1931
Abstract: Explaining the initial mass function (IMF) of stars is a long-standing problem in astrophysics. The number of complex mechanisms involved in the process of star cluster formation, such as turbulence, magnetic fields and stellar feedback,… read more here.

DOI: 10.1093/mnras/stac462
Abstract: A dynamically relaxed dense cluster comprised of about 40 stars (the so-called S-stars) inhabits the central region of the Galaxy. Their stars revolve around the Sgr A* massive object. To understand the dynamical evolution of… read more here.

DOI: 10.1093/mnras/stad1092
Abstract: Using radiation-hydrodynamic cosmological simulations, we present a detailed (0.1 pc resolution), physically motivated portrait of a typical-mass dwarf galaxy before the epoch of reionization, resolving the formation and evolution of star clusters into individual $10\:\mathrm{{\rm M}_{\odot… read more here.

DOI: 10.1093/mnras/stad1256
Abstract: We investigate the effects of an oscillating gas filament on the dynamics of its embedded stellar clusters. Motivated by recent observational constraints, we model the host gas filament as a cylindrically symmetrical potential, and the… read more here.

DOI: 10.1093/mnras/stae2191
Abstract: Recent observations of high-redshift galaxies have revealed starburst galaxies with excessive amounts of nitrogen, well above that expected in standard evolutionary models. The Sunburst Arc galaxy, particularly its young and massive star cluster, represents the… read more here.

DOI: 10.1093/mnras/sty1277
Abstract: One of the main theories for explaining the formation of spiral arms in galaxies is the stationary density wave theory. This theory predicts the existence of an age gradient across the arms. We use the… read more here.
