Puzzles in Galaxy Scaling Relations


Title: Puzzles in Galaxy Scaling Relations
Speaker: Stephane Courteau (Queen's University)
Date: Thursday, 8 December 2016
Time: 11:00 - 12:00
Venue: SAAO Auditorium


Galaxies like our Milky Way can be described in terms of their structure, dynamics, and stellar populations.  Some very robust correlations between galaxy structural properties, such as total luminosity, maximum circular velocity, and size display rather small scatter, hinting at well-regulated galaxy formation processes. A major challenge to understanding these scaling relations, their tight scatter, and ultimately galaxy formation and evolution, is the elusive interplay between visible and dark matter. I will present the latest constraints on galaxy scaling relations and their link with modern cosmological models.
