Extending the M_(bh)-sigma diagram with dense nuclear star clusters
Extending the M_(bh)-sigma diagram dense nuclear star clusters
2012/2/21
Abridged: Four new nuclear star cluster masses, M_nc, plus seven upper limits, are provided for galaxies with previously determined black hole masses, M_bh. Together with a sample of 64 galaxies with ...
Statistical comparison of clouds and star clusters
Statistical comparison clouds star clusters
2011/1/13
The extent to which the projected distribution of stars in a cluster is due to a large-scale radial gradient, and the extent to which it is due to fractal sub-structure, can be quantified -- statistic...
Star Clusters in M31: Old Clusters with Bar Kinematics
catalogs – galaxies individual (M31) – galaxies star clusters – globular clusters
2010/11/12
We analyze our accurate kinematical data for the old clusters in the inner regions of M31. These velocities are based on high S/N Hectospec data (Caldwell et al 2010). The data are well suited for ana...
The Massive Star Content of Circumnuclear Star Clusters in M83
ircumnuclear Star Clusters
2010/11/16
The circumnuclear starburst of M83 (NGC 5236), the nearest such example (4.6 Mpc), constitutes an ideal site for studying the massive star IMF at high metallicity (12+log[O/H]=9.1±0.2, Bresolin & Kenn...
SDSS-III/APOGEE: Detailed Abundances of Galactic Star Clusters
SDSS-III/APOGEE Detailed Abundances Galactic Star Clusters
2010/11/15
Sloan Digital Sky Survey III/Apache Point Observatory Galactic Evolution Experiment (SDSS-III/APOGEE) is a large-scale spectroscopic survey of Galactic stars and star clusters. The SDSS-III/APOGEE sur...
The star formation history of the Large Magellanic Cloud as seen by star clusters and stars
galaxies evolution - galaxies: individual galaxies stellar content - galaxies star clusters
2010/11/10
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 test...
Over the past years observations of young and populous star clusters have shown that the stellar initial mass function (IMF) can be conveniently described by a two-part power-law with an exponent 2 =...
On the origin of the red excess in very young super star clusters: the case of SBS 0335-052E
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2011/1/7
The spectral energy distribution analysis of very young unresolved star clusters challenges our understanding of the cluster formation process. Studies of resolved massive clusters in the Milky Way an...
In Galactic studies a distinction is made between (open) star clusters and associations. For barely resolved objects at a distance of several Mpc this distinction is not trivial to make.
Assessment of Stellar Stratification in Three Young Star Clusters in the Large Magellanic Cloud

2010/3/8
(abridged) We present a comprehensive study of stellar stratification in young star clusters in the Large Magellanic Cloud (LMC). We apply our recently developed effective radius method for the assess...
