The connection between energetic feedback in low-mass galaxies and the enrichment of the intergalactic medium.

该项目的目标是分析活动星系核(AGN)和超新星反馈机制在清洁发展机制光晕抛射金属过程中的作用。具体地说，将对矮小星系进行调查，因为有人建议，它们应该对星际介质中存在的大部分金属负责。将使用高质量分辨率的现代流体动力学宇宙学模拟来研究这一现象，以期复制预期的金属分布。

The goal of this project is to analyse the effect of active galactic nucleus (AGN) and supernova feedback mechanisms in the ejection of metals from lambda CDM halos. Specifically, dwarf galaxies will be investigated as it has been suggested that they ought to be responsible for the bulk of metals present in the intergalactic medium. Modern hydrodynamical cosmology simulations with high mass resolutions will be used to investigate this with a view to replicating the expected distribution of metals.
