Title: Winds, Super-winds and AGN: the broken hierarchy of galaxy formation

Date: Thursday, June 1st, 2006
Time: 16:00
Venue: SISSA, Room D

Abstract:
In my talk I'll discuss the difficulties for theoretical models of galaxy formation. I'll suggest that one possibility is that winds in young galaxies are highly energetic, almost explosive. These super-winds might drive the ISM of young galaxies out into the intergalactic medium, polluting it with metals but reducing the gas supply available for galaxy formation in the present-day universe. The observational challenge is then to try to observe such superwinds, and I will discuss observational work hinting at their existence. I will turn to Integral Field Spectroscopy as a technique for investigating young galaxies in more detail, and in particular a means of probing the nature and energetics of such winds. I will present results on the LAB2 galaxy, and recent observations of a strongly lensed z=5 galaxy behind the RCS0224 cluster.
