cds-question@unistra.frgalaxiesglobular-star-clustershst-photometryImages from the Hubble Space Telescope Advanced Camera for surveys are used to carry out a new photometric study of the globular clusters (GCs) in M104, the Sombrero galaxy. The primary focus of our study is the characteristic distribution function of linear sizes [size distribution function (SDF)] of the GCs. We measure the effective radii for 652 clusters with point spread function-convolved King and Wilson dynamical model fits. The SDF is remarkably similar to those measured for other large galaxies of all types, adding strong support to the view that it is a 'universal' feature of GC systems. We use the Sombrero and Milky Way data and the formation models of Baumgardt & Kroupa (2007MNRAS.380.1589B) to develop a more general interpretation of the SDF for GCs.2010MNRAS.401.1965Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/401/1965CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/132/1593 : BVR photometry of NGC 4594 globular clusters (Spitler+, 2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/401/1965https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/401/1965http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/401/1965https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/401/1965https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/401/1965http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/401/1965GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/401/1965/table1 (Photometry and structural parameters for GCs in M104)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/401/1965/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/401/1965/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/401/1965/table1?GETtext/xml+votable180.050000true190.04184-11.63908610.0055555555555555566/25083https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/401/1965?format=asciiOpticaldefaultJ/MNRAS/401/1965/table1Photometry and structural parameters for GCs in M104recnoRecord number assigned by the VizieR team.
