Membership Analysis and 3D Kinematics of the Star-forming Complex around Trumpler 37 Using Gaia-DR3
The Astrophysical Journal, 2023 Identifying and characterizing young populations of star-forming regions are crucial to unraveling their properties. In this regard, Gaia-DR3 data and machine-learning tools are very useful for studying large star-forming complexes.

THE TWO MOLECULAR CLOUDS IN RCW 38: EVIDENCE FOR THE FORMATION OF THE YOUNGEST SUPER STAR CLUSTER IN THE MILKY WAY TRIGGERED BY CLOUD–CLOUD COLLISION [PDF]
, 2015 We present distributions of two molecular clouds having velocities of 2 and 14 km s−1 toward RCW 38, the youngest super star cluster in the Milky Way, in the 12CO J = 1–0 and 3–2 and 13CO J = 1–0 transitions.

Odessa Astronomical Publications, 2017 Analysis of the absolute uvby photometry of the Open Clusters NGC 6910 and NGC 6913 show well-defined peaks that clearly define the accumulation of stars. Differential photometry of five stars in the direction of each cluster determines that at least two

The Astrophysical Journal Letters, 2023 We combine JWST/NIRCam imaging and MUSE data to characterize the properties of galaxies in different environmental conditions in the cluster Abell2744 ( z = 0.3064) and in its immediate surroundings. We investigate how galaxy colors, morphology, and star-

Star Cluster Survival in Star Cluster Complexes under Extreme Residual Gas Expulsion
, 2005 After the stars of a new, embedded star cluster have formed they blow the remaining gas out of the cluster. Especially winds of massive stars and definitely the on-set of the first supernovae can remove the residual gas from a cluster.

MOCCA code for star cluster simulations – IV. A new scenario for intermediate mass black hole formation in globular clusters [PDF]
, 2015 We discuss a new scenario for the formation of intermediate mass black holes (IMBHs) in dense star clusters. In this scenario, IMBHs are formed as a result of dynamical interactions of hard binaries containing a stellar-mass black hole (BH), with other ...

Modeling Dense Star Clusters in the Milky Way and Beyond with the CMC Cluster Catalog [PDF]
Astrophysical Journal Supplement Series, 2019 We present a set of 148 independent N-body simulations of globular clusters (GCs) computed using the code CMC (Cluster Monte Carlo). At an age of ∼10–13 Gyr, the resulting models cover nearly the full range of cluster properties exhibited by the Milky ...

HENIZE 2–10: THE ONGOING FORMATION OF A NUCLEAR STAR CLUSTER AROUND A MASSIVE BLACK HOLE [PDF]
, 2015 The central region of the galaxy Henize 2–10 hosts a black hole (BH) candidate with a mass Log M BH / M ⊙ = 6.3 ± 1.1 ?> . While this putative BH does not appear to coincide with any central stellar overdensity, it is surrounded by 11 young massive ...

The Astrophysical Journal Supplement Series, 2023 Despite having data for over 10 ^9 stars from Gaia, less than 10 ^4 star clusters and candidates have been discovered. In particular, distant star clusters are rarely identified, due to the challenges posed by heavy extinction and great distance. However,
