A homogeneous three-dimensional view of Molecular Cloud kinematics out to 2.5 kpc. Using Young Stellar Objects and Open Clusters as complementary tracers
The study used Young Stellar Objects (YSOs) and young Open Clusters (OCs) to map the 3D motions of molecular clouds up to 2.5 kpc. It found that YSOs and OCs share consistent kinematics, proving they both trace the bulk motion of their parent gas clouds. This validates using these two tracers together to reconstruct cloud movements and track the Solar System's path.
