Severo Ochoa Seminar by Prof. S. Courteau

On Tuesday November 25th, the Severo Ochoa visitor, Prof. Stephane Courteau from the Queen's University (Canada), will give a Severo Ochoa Seminar entitled Puzzles in the Scaling Relations of Spiral Galaxies.

Start date: 25 Nov, 2014 - 10:30
End date: 25 Nov, 2014 - 12:00
Location: Aula, IAC Headquarters, Tenerife.
Organizer: Instituto de Astrofísica de Canarias

Abstract:

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