摘要:

ESO远距离聚类调查(EDisCS,P.I.西蒙·D·M White,LP 166.A-0162)是ESO的一个大型计划,旨在研究z = 0.4 - 1的星系团和星系团星系。在星团中、在群体中和在场中,恒星形成活动的演化有何不同?它取决于星系团的质量和/或局部星系的密度吗?在不同的环境中,星暴和星暴后的星系有多大的相关性?星系的结构是否有演化,如果有,这是否与它们的恒星形成活动有关?这些是使用EDisCS数据集调查的一些主要问题。

英文摘要:

The ESO Distant Cluster Survey (EDisCS, P.I. Simon D.M. White, LP 166.A-0162) is an ESO large programme aimed at studying clusters and cluster galaxies at z=0.4-1. How different is the evolution of the star formation activity in clusters, in groups and in the field? Does it depend on cluster mass and/or the local galaxy density? How relevant are starburst and post-starburst galaxies in the different environments? Is there an evolution in the galaxies' structures, and if so, is this related to the changes in their star formation activity? These are some of the main questions that have been investigated using the EDisCS dataset.
