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 ...
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...
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...
