VLA 22 GHz Imaging of Massive Star Formation in Local Wolf–Rayet Galaxies
The Astrophysical JournalWe present 22 GHz imaging of regions of massive star formation within the Local Wolf–Rayet Galaxy Sample, a NSF Karl G. Jansky Very Large Array survey of 30 local galaxies showing spectral features of Wolf–Rayet (WR) stars.

The Astronomical JournalWe present the results from spectroscopic and photometric analysis of 17 globular cluster (GC) candidates in the Irr II galaxy NGC 3077. The GC candidates were selected on the Hubble Space Telescope images and were cleaned of foreground Galatic stars ...

Forest Fire Clustering: A Novel Tool for Identifying Star Members of Clusters
The Astronomical JournalIn the era of a data-driven landscape, the development of an efficient and interpretable method has become a pivotal tool for robustly identifying memberships of clusters.

The Astrophysical JournalYoung massive clusters (YMCs) are dense aggregates of young stars and are often speculated as potential precursors to globular clusters. However, the formation mechanism of massive and compact gas clumps that precede YMCs remains unknown.

The Spatial Distribution of Intracluster Globular Clusters in the Fornax Cluster
The Astrophysical JournalWe investigate the spatial distribution of the intracluster globular clusters (ICGCs) detected in the core of the Fornax galaxy cluster. By separately modeling different components of the observed population of globular clusters (GCs), we confirm the ...

Revisit of 77 Clusters Candidates with Multiple Main Sequences using Gaia DR3
The Astronomical JournalGaia DR3 data provide the latest and full astrometric data for more than 1.5 billion sources, and these allow us to revisit the 77 special open cluster candidates collected from LISC star cluster catalog.

oMEGACat. IV. Constraining the Ages of Omega Centauri Subgiant Branch Stars with HST and MUSE
The Astrophysical JournalWe present age estimates for over 8100 subgiant branch (SGB) stars in Omega Centauri ( ω Cen) to study its star formation history. Our large data set, which combines multi-wavelength Hubble Space Telescope photometry with MUSE metallicities, provides an ...

Evolution of Star Clusters within Galaxies Using Self-consistent Hybrid Hydro/N-body Simulations
The Astrophysical JournalWe introduce a GPU-accelerated hybrid hydro/ N -body code ( Enzo-N ) designed to address the challenges of concurrently simulating star clusters and their parent galaxies.

Multiple Machine Learning as a Powerful Tool for Star Cluster Analysis
The Astronomical JournalThis work proposes a multiple machine learning method (MMLM) aiming to improve the accuracy and robustness of the analysis of star clusters. The MMLM performance is evaluated by applying it to the reanalysis of an old binary cluster candidate—comprised ...
