PHANGS–JWST First Results: Massive Young Star Clusters and New Insights from JWST Observations of NGC 1365 [PDF]
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

JWST/NIRCam Probes Young Star Clusters in the Reionization Era Sunrise Arc [PDF]
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.

New insights on binary black hole formation channels after GWTC-2: young star clusters versus isolated binaries [PDF]
Monthly notices of the Royal Astronomical Society, 2021 With the recent release of the Second Gravitational Wave Transient Catalog (GWTC-2), which introduced dozens of new detections, we are at a turning point of gravitational wave astronomy, as we are now able to directly infer constraints on the ...

Mass and Rate of Hierarchical Black Hole Mergers in Young, Globular and Nuclear Star Clusters [PDF]
Symmetry, 2021 Hierarchical mergers are one of the distinctive signatures of binary black hole (BBH) formation through dynamical evolution. Here, we present a fast semi-analytic approach to simulate hierarchical mergers in nuclear star clusters (NSCs), globular ...

Looking for Obscured Young Star Clusters in NGC 1313 [PDF]
, 2021 Using recently acquired Hubble Space Telescope NIR observations (J, Paβ, and H bands) of the nearby galaxy NGC 1313, we investigate the timescales required by a young star cluster to emerge from its natal cloud.

Stellar mergers as the origin of the blue main-sequence band in young star clusters [PDF]
Nature Astronomy, 2022 Recent high-quality Hubble Space Telescope photometry shows that the main-sequence stars of young star clusters form two discrete components in the colour–magnitude diagram. On the basis of their distribution in the colour–magnitude diagram, we show that

Dynamics of black hole–neutron star binaries in young star clusters [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 Young star clusters are likely the most common birthplace of massive stars across cosmic time and influence the formation of compact binaries in several ways.

Star cluster ecology III: Runaway collisions in young compact star\n clusters [PDF]
, 1998 The evolution of young compact star clusters is studied using N-body simulations in which both stellar evolution and physical collisions between stars are taken into account. The initial conditions are chosen to represent R136, a compact star cluster in the 30 Doradus region of the Large Magellanic Cloud.

Multi-color observations of Young Star Clusters [PDF]
Highlights of Astronomy, 2003 AbstractWe present a new set of evolutionary synthesis models of our GALEV code, specifically developed to include the gaseous emission of presently forming star clusters, in combination with an advanced tool to compare large model grids with multi-color broad-band observations of YSC systems. Tests and first applications are presented.
