Unbound young stellar systems, the loose ensembles of physically related young bright
stars, trace the typical regions of recent star formation in galaxies. Their morphologies vary …

We analyze the 3D morphology and kinematics of 13 open clusters (OCs) located within 500
pc of the Sun, using Gaia EDR 3 and kinematic data from the literature. Members of OCs are …

We present a study of the hierarchical clustering of the young stellar clusters in six local (3–
15 Mpc) star-forming galaxies using Hubble Space Telescope broadband WFC3/UVIS UV …

ABSTRACT I develop a high-velocity galaxy collision model to explain a rare but puzzling
phenomenon, namely the apparent existence of ultra-diffuse galaxies with little dark matter …

We present the Star cluster Hunting Pipeline (SHiP) that can identify star clusters in Gaia
second data release (DR2) data and establish a star cluster catalog for the Galactic disk. A …

We present a dynamical friction model based on Chandrasekhar's formula that reproduces
the fast inspiral and stalling experienced by satellites orbiting galaxies with a large constant …

In the context of a project aimed at characterizing the dynamical evolution of old globular
clusters in the Large Magellanic Cloud, we have secured deep HST/WFC3 images of the …

We identify hierarchical structures in the Vela OB2 complex and the cluster pair Collinder
135 and UBC 7 with Gaia EDR3 using the neural network machine-learning algorithm …

Fast, ejected stars have been found around several young star-forming regions, such as the
Orion Nebula Cluster. These ejected stars can be used to constrain the initial density, spatial …

ABSTRACT A number of stellar open cluster (OC) pairs in the Milky Way occupy similar
positions in the phase space (coordinates, parallax, and proper motions) and therefore may …
