SUMMARY:colloquium - Stephane Courteau: Puzzles in Galaxy Structure
DESCRIPTION:Galaxies like our Milky Way can be described in terms of their structure\,\ndynamics\, and stellar populations. Some robust correlations between\ngalaxy structural properties such as stellar mass\, circular velocity\, and \nsize display surprisingly small scatter over many orders of magnitude\, \nhinting at well-regulated galaxy formation processes. A major challenge \nto understanding these scaling relations\, their tight scatter\, and ultimately \ngalaxy formation and evolution\, is the elusive interplay between visible \nand dark matter.  Among others\, the radial acceleration relation\, concept \nof “galaxy diversity”\, intrinsic scatter in galaxy scaling relations\, impact\nof supermassive black hole on galaxies\, and comparisons with numerical \nsimulations of galaxy formation are presented in this context.
