Star-forming Nuclear Clusters in Dwarf Galaxies Mimicking Active Galactic Nucleus Signatures in the Mid-infrared

open access: yesThe Astrophysical Journal
Effectively finding and identifying active galactic nuclei (AGNs) in dwarf galaxies is an important step in studying black hole formation and evolution.

Extended main sequences in star clusters

open access: yesFundamental Research
Extended main sequences (eMSs) and extended main-sequence turn-offs (eMSTOs) are fascinating phenomena that are routinely observed in star clusters. These phenomena strongly challenge the current canonical “simple stellar population” picture of star ...

Young Star Clusters in Starburst Environments

open access: yes, 1996
Recent high-resolution observations with the Hubble Space Telescope (HST) reveal that young star clusters of extraordinary luminosity and compactness ("super star clusters") are commonly found in starburst systems. Cluster formation appears to be a dominant mode of star formation in starbursts.

Identification of Outer Galaxy Cluster Members Using Gaia DR3 and Multidimensional Simulation

open access: yesThe Astronomical Journal
The outer Galaxy presents a distinctive environment for investigating star formation. This study develops a novel approach to identify true cluster members based on unsupervised clustering using astrometry with significant uncertainties.

Massive Clusters and OB Associations as Output of Massive Star Formation in Gaia Era

open access: yesUniverse
Over the past two decades, our understanding of star formation has undergone a major shift, driven by a wealth of data from infrared, submillimeter and radio surveys. The emerging view depicts star formation as a hierarchical process, which predominantly
