Star clusters as tracers of galaxy evolution
Star clusters represent the most common ‘mode’ of star formation. They are found in all types of environments, cascading down from galaxy groups and merging pairs through starbursts to normal galaxies and dwarves and even isolated regions in extragalactic space. As they maintain a link to the overall star formation in a system, they can be used as tracers of the star formation history of enviro...
متن کاملOld Open Clusters as Tracers of Galactic Evolution A. Bragaglia and M. Tosi
1. Why (old) open clusters? Open clusters (OC's) are important to study the properties of the Galactic disk, since they offer information on ages, both absolute and relative, and on the metallicity evolution, both in space and time. In fact, OC's are found in different regions of the disk, cover a large interval in age (from a few Myr to about 10 Gyr) and in metallicity (Z=Z ⊙ /20 to supersolar...
متن کاملClusters as Tracers of Large – Scale Structure
By virtue of their high galaxy space densities and their large spatial separations, clusters are efficient and accurate tracers of the large–scale density and velocity fields. Substantial progress has been made over the past decade in the construction of homogeneous, objectively derived cluster catalogs and in characterizing the spatial distribution of clusters. Consequently, the constraints on...
متن کاملFrom nuclear clusters to halo globulars: Star clusters as basic galactic building blocks
I assess the similarities and differences between the star-formation modes in quiescent spiral galaxies versus those in violent starburst regions, including galactic nuclei. As opposed to the quiescent star-formation mode, current empirical evidence on the star-formation processes in the extreme, high-pressure environments induced by galaxy encounters strongly suggests that star cluster formati...
متن کاملYoung star clusters: Metallicity tracers in external galaxies
Star cluster formation is a major mode of star formation in the extreme conditions of interacting galaxies and violent starbursts. These newly-formed clusters are built from recycled gas, pre-enriched to various levels within the interacting galaxies. Hence, star clusters of different ages represent a fossil record of the chemical enrichment history of their host galaxy, as well as of the host ...
