| « The Violent Processes Shaping Galaxies at High Redshift » |
|
Matthew Lehnert |
| While today, the Universe could be considered in the "age of secular evolution", beyond about 8 Gyrs ago, the Universe was in the "age of feedback and self-regulation". I discuss the properties of galaxies within the first few Gyrs in the age of the Universe as derived from spectroscopic observations of distant galaxies (2-5 and perhaps beyond). These observations are revealing the nature of the physical processes that are shaping the ensemble of galaxies and the important role of feedback and self-regulation in both galaxy and black hole growth. However, we are a long way from a deep understanding of these mechanisms and so I will discuss steps along the way of obtaining this deeper knowledge. |
