Young massive star clusters [PDF]
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.

Young and intermediate-age massive star clusters [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2009 An overview of our current understanding of the formation and evolution of star clusters is given, with 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

Structural Properties of Massive Young Clusters [PDF]
The Astrophysical Journal, 2001 We have retrieved multicolor WFPC2/HST data from the STScI archive for 27 nearby Massive (>= 3x10^4 M_Sun) Young (< 20 Myr) star Clusters (MYCs). The data represents the most-complete-to-date sample of clearly resolved MYCs. We have analyzed their structural properties and have found that they can be classified as either Super Star Clusters (SSCs)

NGC 3603 - a Local Template for Massive Young Clusters [PDF]
Symposium - International Astronomical Union, 2001 We present a study of the star cluster associated with the massive Galactic HII region NGC3603 based on near-IR broad-- and narrowband observations taken with ISAAC/VLT under excellent seeing conditions (

Extremely massive young clusters in NGC 1365 [PDF]
Astronomy & Astrophysics, 2008 In a previous work, three bright MIR/radio sources were discovered in the nuclear region of NGC1365. We here confirm that these sources are young and massive ``embedded'' clusters, and derive their parameters, such as extinction, age and mass. Using ISAAC and VISIR at the VLT we obtained NIR and MIR maps and LR spectra. The dataset is first interpreted

HOW TO FIND YOUNG MASSIVE CLUSTER PROGENITORS [PDF]
The Astrophysical Journal, 2012 We propose that bound, young massive stellar clusters form from dense clouds that have escape speeds greater than the sound speed in photo-ionized gas. In these clumps, radiative feedback in the form of gas ionization is bottled up, enabling star formation to proceed to sufficiently high efficiency so that the resulting star cluster remains bound even ...

Early-forming Massive Stars Suppress Star Formation and Hierarchical Cluster Assembly
The Astrophysical Journal, 2023 Feedback from massive stars plays an important role in the formation of star clusters. Whether a very massive star is born early or late in the cluster formation timeline has profound implications for the star cluster formation and assembly processes. We

X3: A High-mass Young Stellar Object Close to the Supermassive Black Hole Sgr A*
The Astrophysical Journal, 2023 To date, the proposed observation of young stellar objects (YSOs) in the Galactic center still raises the question of where and how these objects could have formed due to the violent vicinity of Sgr A*.

Young massive star clusters in M51 [PDF]
Monthly Notices of the Royal Astronomical Society, 2002 A search for young massive star clusters (YMCs) in the nearby face-on spiral galaxy M51 (NGC 5194) has been carried out using UBV CCD images from the prime focus camera on the Lick 3 meter Shane telescope. The YMC population is found to be quite rich with a specific U-band luminosity T_L(U) = 1.4, consistent with the high current star formation rate of
