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/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.

DOI: 10.1093/mnras/stz1896
Abstract: In this paper, we continue our study on the evolution of black holes (BHs) that receive velocity kicks at the origin of their host star cluster potential. We now focus on BHs in rotating clusters… read more here.

DOI: 10.1093/mnras/stz2721
Abstract: We present an analysis of young star clusters (YSCs) that form in the E-MOSAICS cosmological, hydrodynamical simulations of galaxies and their star cluster populations. Through comparisons with observed YSC populations, this work aims to test… read more here.
