Mass Functions of Giant Molecular Clouds and Young Star Clusters in Six Nearby Galaxies [PDF]
Astrophysical Journal, 2020 We compare the mass functions of young star clusters (ages ≤ 10 Myr) and giant molecular clouds (GMCs) in six galaxies that cover a large range in mass, metallicity, and star formation rate (LMC, M83, M51, NGC 3627, the Antennae, and NGC 3256).

Fast Optical Transients from Stellar-mass Black Hole Tidal Disruption Events in Young Star Clusters [PDF]
Astrophysical Journal, 2020 Observational evidence suggests that the majority of stars may have been born in stellar clusters or associations. Within these dense environments, dynamical interactions lead to high rates of close stellar encounters.

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 ...

Different Fates of Young Star Clusters after Gas Expulsion [PDF]
Astrophysical Journal, 2020 We identify structures of the young star cluster NGC 2232 in the solar neighborhood (323.0 pc) and a newly discovered star cluster, LP 2439 (289.1 pc). Member candidates are identified using the Gaia DR2 sky position, parallax, and proper-motion data by ...

Young Star Clusters in M 31 [PDF]
, 2008 In our study of M31's globular cluster system with MMT/Hectospec, we have obtained high-quality spectra of 85 clusters with ages less than 1 Gyr. With the exception of Hubble V, the young cluster in NGC 205, we find that these young clusters have kinematics and spatial distribution consistent with membership in M31's young disk.

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 ...

Star formation in young star cluster NGC 1893 [PDF]
Monthly Notices of the Royal Astronomical Society, 2007 We present a comprehensive multi-wavelength study of the star-forming region NGC 1893 to explore the effects of massive stars on low-mass star formation. Using near-infrared colours, slitless spectroscopy and narrow-band $H $ photometry in the cluster region we have identified candidate young stellar objects (YSOs) distributed in a pattern from the ...

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.

Hierarchical black hole mergers in young, globular and nuclear star clusters: the effect of metallicity, spin and cluster properties [PDF]
, 2021 We explore hierarchical black hole (BH) mergers in nuclear star clusters (NSCs), globular clusters (GCs) and young star clusters (YSCs), accounting for both original and dynamically assembled binary BHs (BBHs).
