Very-high-energy γ-Ray Emission from Young Massive Star Clusters in the Large Magellanic Cloud

open access: yesThe Astrophysical Journal Letters
The Tarantula Nebula in the Large Magellanic Cloud is known for its high star formation activity. At its center lies the young massive star cluster R136, providing a significant amount of the energy that makes the nebula shine so brightly at many ...

Intermediate-mass Black Hole Progenitors from Stellar Collisions in Dense Star Clusters

open access: yesThe Astrophysical Journal
Very massive stars (VMSs) formed via a sequence of stellar collisions in dense star clusters have been proposed as the progenitors of massive black hole seeds.

Euclid: Early Release Observations – The star cluster systems of the Local Group dwarf galaxies IC 10 and NGC 6822★

open access: yesAstronomy & Astrophysics
Star clusters are valuable indicators of galaxy evolution, offering insights into the buildup of stellar populations across cosmic time. Understanding the intrinsic star cluster populations of dwarf galaxies is particularly important given these systems’

ALMA Detection of [O iii] 88 μm at z = 12.33: Exploring the Nature and Evolution of GHZ2 as a Massive Compact Stellar System

open access: yesThe Astrophysical Journal Letters
We present Atacama Large Millimeter/submillimeter Array observations on the high-redshift galaxy GHZ2 and report a successful detection of the rest-frame 88 μ m atomic transition from doubly ionized oxygen at z = 12.3327 ± 0.0035.

The Evaporating Massive Embedded Stellar Cluster IRS 13 Close to Sgr A*. II. Kinematic Structure

open access: yesThe Astrophysical Journal
The existence of two distinct and apparently unrelated populations of dusty stellar objects in the Nuclear Stellar Cluster of the Milky Way, namely IRS 13 and the S-cluster, are potentially prone to a general process describing the star formation history

Evidence Against Primordial Mass Segregation in Young Open Clusters: A Bayesian Multiscale Analysis of 3881 Gaia DR3 Clusters

open access: yesThe Astronomical Journal
The origin of mass segregation in open clusters—whether it is primordial (imprinted at birth) or dynamical (evolved over time)—remains a subject of intense debate. We present a comprehensive multi-scale analysis of 3881 open clusters using high-precision
