On the Mass of Dense Star Clusters in Starburst Galaxies from Spectro-Photometry
The mass of unresolved young star clusters derived from spectro-photometric data may well be off by a factor of 2 or more once the migration of massive stars driven by mass segregation is accounted for. We quantify this effect for a large set of cluster parameters, including variations in the stellar IMF, the intrinsic cluster mass, and mean mass density. Gas-dynamical models coupled with the C...
متن کاملMassive star clusters in dwarf starburst galaxies
I will discuss the presence of massive star clusters in starburst galaxies with an emphasis on low mass galaxies outside the local group. I will show that such galaxies, with respect to their mass and luminosity, may be very rich in young luminous clusters.
متن کاملRadio Observations of Super Star Clusters in Dwarf Starburst Galaxies
We present new radio continuum observations of two dwarf starburst galaxies, NGC3125 and NGC5408, with observations at 4.80GHz (6cm) and 8.64GHz (3cm), taken with the Australia Telescope Compact Array (ATCA). Both galaxies show a complex radio morphology with several emission regions, mostly coincident with massive young star clusters. The radio spectral indices of these regions are negative (w...
متن کاملStarburst Galaxies in Clusters
The nature of the starburst phenomenon in galaxies is investigated using a narrow band color system designed to study color evolution in distant clusters. Work on zero redshift, luminous far-IR galaxies, calibrated by starburst models, demonstrates the usefulness of this color system in isolating starburst from normal star-forming colors, and also demonstrates a strong correlation with far-IR c...
متن کاملStar Formation in Starburst Galaxies
Some of the basic properties of star formation in starburst galaxies are reviewed. I discuss triggering and termination mechanisms in starbursts and provide estimates of star-formation rates. Galaxies with ongoing star formation at low and high redshift are compared.
