Young Massive Star Clusters [PDF]
Annual Review of Astronomy and Astrophysics, 2010 Young massive clusters (YMCs) 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.

Radii of young star clusters in nearby galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 ABSTRACT We measure the projected half-light radii of young star clusters in 31 galaxies from the Legacy Extragalactic UV Survey (LEGUS). We implement a custom pipeline specifically designed to be robust against contamination, which allows us to measure radii for 6097 clusters.

Young and intermediate-age massive star clusters [PDF]
Philosophical Transactions Series A, Mathematical, Physical, and Engineering Sciences, 2010 An overview of our current understanding of the formation and evolution of star clusters is given, with the main emphasis on high-mass clusters. Clusters form deeply embedded within dense clouds of molecular gas. Left-over gas is cleared within a few million years and, depending on the efficiency of star formation, the clusters may

The initial properties of young star clusters in M83 [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT The initial sizes and masses of massive star clusters provide information about the cluster formation process and also determine how cluster populations are modified and destroyed, which have implications for using clusters as tracers of galaxy assembly.

The bound fraction of young star clusters [PDF]
Astronomy and Astrophysics, 2017 The residual gas within newly formed star clusters is expelled through stellar feedback on timescales ~ 1 Myr. The subsequent expansion of the cluster results in an unbinding of a fraction of stars before the remaining cluster members can re-virialize and form a surviving cluster.

Young Star Clusters in the LMC [PDF]
Symposium - International Astronomical Union, 1991 We discuss the integrated colours, kinematics, formation, dynamical evolution and initial mass functions of the young globular star clusters in the Large Magellanic Cloud (LMC). Because these clusters are so young, they offer us insights, unobtainable from the old globular clusters in our Galaxy, into the formation and early dynamical evolution of ...

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

Be Stars in Young LMC Clusters [PDF]
Symposium - International Astronomical Union, 1994 Slitless field Hα spectroscopy with a resolution of 0.2 nm has detected numerous Be stars in 3 young open star clusters in the LMC but only a few each in one Galactic and one LMC cluster. The line widths indicate rapid rotation as is typical of Galactic field Be stars.

Young Star Clusters: Progenitors of Globular Clusters!? [PDF]
Highlights of Astronomy, 2005 AbstractStar cluster formation is a major mode of star formation in the extreme conditions of interacting galaxies and violent starbursts. Young clusters are observed to form in a variety of such galaxies, a substantial number resembling the progenitors of globular clusters in mass and size, but with significantly enhanced metallicity.
