Massive 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 کاملGlobular Clusters in Dwarf Galaxies
Recent work on globular cluster systems in dwarf galaxies outside the Local Group is reviewed. Recent large imaging surveys with the Hubble Space Telescope and follow-up spectroscopy with 8-m class telescopes now allow us to compare the properties of massive star clusters in a wide range of galaxy types and environments. This body of work provides important constraints for theories of galaxy an...
متن کاملGlobular Clusters in Dwarf Galaxies
Data are presently available on the luminosities and half-light radii of 101 globular clusters associated with lowluminosity parent galaxies. The luminosity distribution of globulars embedded in dwarf galaxies havingMv > −16 is found to differ dramatically from that for globular clusters surrounding giant host galaxies with Mv < −16. The luminosity distribution of globular clusters in giant gal...
متن کاملMassive star clusters in galaxies.
The ensemble of all star clusters in a galaxy constitutes its star cluster system. In this review, the focus of the discussion is on the ability of star clusters, particularly the systems of old massive globular clusters (GCs), to mark the early evolutionary history of galaxies. I review current themes and key findings in GC research, and highlight some of the outstanding questions that are eme...
متن کاملGas Stripping of Dwarf Galaxies in Clusters of Galaxies
Many clusters of galaxies contain an appreciable amount of hot gas, the intracluster medium. As a consequence, gas will be stripped from galaxies that move through the inter cluster medium, if the ram pressure exceeds the internal gravitational force. We study the interaction between the intracluster medium and an extended gas component of dwarf galaxies confined by a surrounding cold dark matt...
