The dual effect of group-scale environments on galaxy quenching during cluster infall: pre-processing and protection
Haoran Dou, Heng Yu, Xiaolan Hou
Context. It is well established that the cluster environment effectively quenches star formation in member galaxies. Amis. We aim to explore how the accretion path of infalling gal…
The Hierarchical Structure of the Open Cluster NGC 752
Delong Jia, Heng Yu, Zhengyi Shao +1
The structure of open clusters provides key insights into their evolution and the dynamics of the Milky Way. Using Gaia DR3 data, we applied a hierarchical clustering algorithm to…
Estimating infall times of galaxies around clusters: how accurately can it be done with observational data?
Haoran Dou, Heng Yu
Context. The environment plays a crucial role in galaxy evolution, particularly for galaxies infalling into clusters. Accurately estimating the infall times of galaxies from observ…
The destiny of open cluster NGC 6530: past and future
Delong Jia, Heng Yu, Zhengyi Shao +1
Studying the structures of open clusters is crucial for understanding stellar evolution and galactic dynamics. Based on Gaia DR3 data, we apply the hierarchical clustering algorith…
