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)

Young massive clusters in the interacting LIRG Arp 299: evidence for the dependence of star cluster formation and evolution on environment [PDF]
Monthly notices of the Royal Astronomical Society, 2018 Archival WFC3/UVIS imaging of Arp 299 (NGC 3690E + NGC 3690W) is retrieved to investigate the young massive cluster (YMC) population of this ongoing merger. We extract 2182 cluster candidates, including 1323 high confidence photometric sources. Multiband

GW190521 formation via three-body encounters in young massive star clusters [PDF]
Monthly notices of the Royal Astronomical Society, 2021 GW190521 is the most massive binary black hole (BBH) merger observed to date, and its primary component lies in the pair-instability (PI) mass gap. Here, we investigate the formation of GW190521-like systems via three-body encounters in young massive ...

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

Gravitational waves from coalescing massive black holes in young dense clusters [PDF]
, 2006 HST observations reveal that young massive star clusters form in gas-rich environments like the Antenn{\ae} galaxy which will merge in collisional processes to form larger structures.

Massive Young Clusters in Nearby Galaxies [PDF]
Symposium - International Astronomical Union, 2001 We study the size distribution of massive young clusters (MYCs) and of the cavities around them. We discuss the existence of two cluster populations and we find evidences for molecular cloud confinement in the early stages of development.

Binary Black Hole Mergers from Young Massive and Open Clusters: Comparison to GWTC-2 Gravitational Wave Data [PDF]
Astrophysical Journal Letters, 2021 Several astrophysical scenarios have been proposed to explain the origin of the population of binary black hole (BBH) mergers detected in gravitational waves by the LIGO/Virgo Collaboration.

An HST Study of the Substellar Population of NGC 2024
The Astrophysical Journal, 2023 We performed an HST/WFC3-IR imaging survey of the young stellar cluster NGC 2024 in three filters probing the 1.4 μ m H _2 O absorption feature, characteristic of the population of low-mass and substellar-mass objects down to a few Jupiter masses.

Property of young massive clusters in a galaxy–galaxy merger remnant [PDF]
Nippon Tenmon Gakkai obun kenkyu hokoku, 2018 We investigate the properties of young massive clusters (YMCs) in a galaxy-galaxy merger remnant by analyzing the data obtained by a gas rich major merger simulations in Matsui et al. 2012. We found that the YMCs are distributed at a few $\rm kpc$ and at

Observational Evidence of the Merging of Filaments and Hub Formation in G083.097+03.270
The Astrophysical Journal, 2023 We uncover a hub–filament system correlated with massive young stellar associations in G083.097+03.270. Diagnosed with simultaneous ^12 CO, ^13 CO, and C ^18 O line observations, the region is found to host two distinct and elongated filaments having ...
