The Stellar Content of Obscured Galactic Giant H II Regions: II. W42 [PDF]
, 2000 We present near infrared J, H, and K images and K-band spectroscopy in the giant HII region W42. A massive star cluster is revealed; the color-color plot and K-band spectroscopic morphology of two of the brighter objects suggest the presence of young ...

STAR CLUSTER FORMATION WITH STELLAR FEEDBACK AND LARGE-SCALE INFLOW [PDF]
, 2015 During star cluster formation, ongoing mass accretion is resisted by stellar feedback in the form of protostellar outflows from the low-mass stars and photo-ionization and radiation pressure feedback from the massive stars.

, 2006 Star clusters are observed in almost every galaxy. In this thesis we address several fundamental problems concerning the formation, evolution and disruption of star clusters. From observations of (young) star clusters in the interacting galaxy M51, we found that clusters are formed in complexes of stars and star clusters.

Cluster and Double Star observations of dipolarization [PDF]
Annales Geophysicae, 2005 We studied two types of dipolarization events with different IMF conditions when Cluster and Double Star (TC-1) were located in the same local time sector: 7 August 2004, 18:00-24:00 UT, during a disturbed southward/northward IMF interval, and 14

Intergalactic stars in the Fornax cluster [PDF]
Monthly Notices of the Royal Astronomical Society, 1997 We have identified ten candidate intergalactic planetary nebulae in the Fornax galaxy cluster. These objects were found during observations in 1992 and 1993 in three fields chosen well away from any Fornax galaxy at 15 arcmin, 30 arcmin, and 45 arcmin from the centre of Fornax.

The reversal of the SF-density relation in a massive, X-ray selected galaxy cluster at z=1.58: results from Herschel [PDF]
, 2014 Dusty, star-forming galaxies have a critical role in the formation and evolution of massive galaxies in the Universe. Using deep far-infrared imaging in the range 100-500um obtained with the Herschel telescope, we investigate the dust-obscured star ...

Dissolving star cluster candidates [PDF]
, 2000 We present a list of 34 neglected entries from star cluster catalogues located at relatively high galactic latitudes ($|b| >$ 15$^{\circ}$) which appear to be candidate late stages of star cluster dynamical evolution. Although underpopulated with respect

KIM 3: AN ULTRA-FAINT STAR CLUSTER IN THE CONSTELLATION OF CENTAURUS [PDF]
, 2015 We report the discovery of an ultra-faint star cluster in the constellation of Centaurus. This new stellar system, Kim 3, features a half-light radius of r h = 2.29 − 0.52 + 1.28 ?> pc and a total luminosity of MV = +0.7 ± 0.3. Approximately 26 stars are

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

Massive star and star cluster formation [PDF]
Proceedings of the International Astronomical Union, 2006 AbstractI review the status of massive star formation theories: accretion from collapsing, massive, turbulent cores; competitive accretion; and stellar collisions. I conclude the observational and theoretical evidence favors the first of these models.
