The star formation history of the Large Magellanic Cloud as seen by star clusters and stars [PDF]

open access: yes, 2010
The aim of this work is to test to what extent the star cluster population of a galaxy can be utilised to constrain or estimate the star formation history, with the Large Magellanic Cloud as our testbed. We follow two methods to extract information about the star formation rate from star clusters, either using only the most massive clusters ...

Double Star/Cluster observation of neutral sheet oscillations on 5 August 2004 [PDF]

open access: yesAnnales Geophysicae, 2005
Previous Cluster observations have shown that the flapping motions of the Earth's magnetotail are of internal origin and that kink-like waves are emitted from the central part of the tail and propagate toward the tail flanks. The newly launched Double

JWST Observations of Starbursts: Massive Star Clusters in the Central Starburst of M82

open access: yesThe Astrophysical Journal Letters
We present a near-infrared (NIR) candidate star cluster catalog for the central kiloparsec of M82 based on new JWST NIRCam images. We identify star cluster candidates using the F250M filter, finding 1357 star cluster candidates with stellar masses >10 ^4

The old Nuclear Star Cluster in the Milky Way [PDF]

open access: yes, 2014
We derive new constraints on the mass, rotation, orbit structure and statistical parallax of the Galactic old nuclear star cluster (NSC) and the mass of the supermassive black hole.

High-Mass Star and Massive Cluster Formation in the Milky Way [PDF]

open access: yesAnnual Review of Astronomy and Astrophysics, 2017
This review examines the state-of-the-art knowledge of high-mass star and massive cluster formation, gained from ambitious observational surveys, which acknowledges the multiscale characteristics of these processes.

The Prevalence and Impact of Wolf-Rayet Stars in Emerging Massive Star Clusters [PDF]

open access: yes, 2016
We investigate Wolf-Rayet (WR) stars as a source of feedback contributing to the removal of natal material in the early evolution of massive star clusters. Despite previous work suggesting that massive star clusters clear out their natal material before the massive stars evolve into the WR phase, WR stars have been detected in several emerging massive ...

Nitrogen-enriched, Highly Pressurized Nebular Clouds Surrounding a Super Star Cluster at Cosmic Noon

open access: yesThe Astrophysical Journal, 2023
Strong lensing offers a precious opportunity for studying the formation and early evolution of super star clusters that are rare in our cosmic backyard.

Surface brightness profile of the Milky Way’s nuclear star cluster [PDF]

open access: yes, 2014
Context. Although the Milky Way nuclear star cluster (MWNSC) was discovered more than four decades ago, several of its key properties have not been determined unambiguously up to now because of the strong and spatially highly variable interstellar ...

Destruction of star clusters due to the radial migration in spiral galaxies [PDF]

open access: yes, 2012
Most stars in galactic disks are believed to be born as a member of star clusters or associations. Star clusters formed in disks are disrupted due to the tidal stripping and the evolution of star clusters themselves, and as a results new stars are supplied to the galactic disks.

MODELING JET AND OUTFLOW FEEDBACK DURING STAR CLUSTER FORMATION [PDF]

open access: yes, 2014
Powerful jets and outflows are launched from the protostellar disks around newborn stars. These outflows carry enough mass and momentum to transform the structure of their parent molecular cloud and to potentially control star formation itself.
