Annual Review of Astronomy and Astrophysics, 2010 Young massive clusters are dense aggregates of young stars that form the fundamental building blocks of galaxies. Several examples exist in the Milky Way Galaxy and the Local Group, but they are particularly abundant in starburst and interacting galaxies.

Dust-buried Compact Sources in the Dwarf Galaxy NGC 4449
The Astrophysical Journal, 2023 Multiwavelength images from the Hubble Space Telescope covering the wavelength range 0.27–1.6 μ m show that the central area of the nearby dwarf galaxy NGC 4449 contains several tens of compact sources that are emitting in the hydrogen recombination line

The Astrophysical Journal Letters, 2023 A primary new capability of JWST is the ability to penetrate the dust in star-forming galaxies to identify and study the properties of young star clusters that remain embedded in dust and gas. In this Letter we combine new infrared images taken with JWST

Clustering Properties of Intermediate and High-mass Young Stellar Objects
The Astronomical Journal, 2023 We have selected 337 intermediate- and high-mass young stellar objects (YSOs; 1.5–20 M _⊙ ) well-characterized with spectroscopy. By means of the clustering algorithm HDBSCAN, we study their clustering and association properties in the Gaia DR3 catalog ...

JWST/NIRCam Probes Young Star Clusters in the Reionization Era Sunrise Arc
The Astrophysical Journal, 2023 Star cluster formation in the early universe and its contribution to reionization remains largely unconstrained to date. Here we present JWST/NIRCam imaging of the most highly magnified galaxy known at z ∼ 6, the Sunrise arc.

PHANGS–JWST First Results: Dust-embedded Star Clusters in NGC 7496 Selected via 3.3 μm PAH Emission
The Astrophysical Journal Letters, 2023 The earliest stages of star formation occur enshrouded in dust and are not observable in the optical. Here we leverage the extraordinary new high-resolution infrared imaging from JWST to begin the study of dust-embedded star clusters in nearby galaxies ...

From the Top Down and Back Up Again: Star Cluster Structure from Hierarchical Star Formation [PDF]
, 2018 Young massive star clusters spanning $\sim 10^4 - 10^8 M_\odot$ in mass have been observed to have similar surface brightness profiles. Recent hydrodynamical simulations of star cluster formation have also produced star clusters with this structure.

Filamentary Star Formation in NGC 1275 [PDF]
, 2014 We examine the star formation in the outer halo of NGC~1275, the central galaxy in the Perseus cluster (Abell 426), using far ultraviolet and optical images obtained with the Hubble Space Telescope.

Two Populations of Young Massive Star Clusters in Arp 220 [PDF]
, 2005 We present new optical observations of young massive star clusters in Arp 220, the nearest ultraluminous infrared galaxy, taken in UBVI with the Hubble Space Telescope ACS/HRC camera. We find a total of 206 probable clusters whose spatial distribution is

HOW FAR CAN GET FRB PROGENITOR NEUTRON STARS FROM THEIR BIRTHPLACE?
Вестник. Серия физическая, 2021 The recent studies show evidence of magnetars – young neutron stars being good candidates of fast radio birth sources. Neutron stars can form as remnants of type II supernovae explosions of young stars.
