The influence of residual gas expulsion on the evolution of the Galactic globular cluster system and the origin of the Population II halo

, 2007
We present new results on the evolution of the mass function of the globular cluster system of the Milky Way, taking the effect of residual gas expulsion into account.

Families of dynamically hot stellar systems over ten orders of magnitude in mass

, 2011
Dynamically hot stellar systems, whether star clusters or early-type galaxies, follow well-defined scaling relations over many orders of magnitudes in mass.

A Near-infrared Spectral Library of Very Young Brown Dwarfs and Planetary Mass Objects in the Orion Nebula Cluster

The Astrophysical Journal
Age-benchmark brown dwarf and planetary-mass-object spectroscopy is key to characterizing substellar evolution. In this paper, we present the JHK medium-resolution ( R ∼ 3000) spectra of 25 7–76 M _Jup (spectral types L3.0–M6.0) brown dwarfs and ...

The Impact of Stellar Radiative Feedback on Formation of Young Massive Clusters via Fast H i Gas Collisions

The Astrophysical Journal
Young 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 Journal
We 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 ...

On the efficiency of field star capture by star clusters

, 2007
An exciting recent finding regarding scaling relations among globular clusters is the so-called 'blue tilt': clusters of the blue sub-population follow a trend of redder colour with increasing luminosity.

Revisit of 77 Clusters Candidates with Multiple Main Sequences using Gaia DR3

The Astronomical Journal
Gaia 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.

Massive Star Formation in Luminous Infrared Galaxies: Giant HII Regions and their relation to Super Star Clusters

, 2002
We have used HST/NICMOS H-band narrow-band Pa-alpha (at rest 1.87micron) images to identify star clusters and HII regions respectively in a sample of 8 luminous infrared galaxies (LIRGs).

Evolution of Star Clusters within Galaxies Using Self-consistent Hybrid Hydro/N-body Simulations

The Astrophysical Journal
We 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 Journal
This 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 ...
