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.

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 ...

, 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.

A Catalog of New M33 Star Clusters Based on the HST/WFPC2 Images [PDF]
Astron.J.134:2168-2178,2007, 2007 We present the result of a survey for star clusters in M33 using the HST/WFPC2 archive images. We have found 104 star clusters, including 32 new ones, in the images of 24 fields that were not included in the previous studies. Combining these with previous data in the literature, we increase the number of M33 star clusters found in the HST images to 242.

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

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

On the efficiency of field star capture by star clusters [PDF]
, 2007 An exciting recent finding regarding scaling relations among globular clusters is the so-called 'blue tilt': clusters of the blue sub-population follow a trend of redder colour with increasing luminosity. In this paper we evaluate to which extent field star capture over a Hubble time may explain the 'blue tilt'.

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 ...

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.

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.
