Cluster Influences on Galaxies at Intermediate Redshift

埃林森博士将研究星团环境对中间红移星系的恒星形成和AGN活动的影响。第一个项目是对12个星系进行详细的光谱和光度研究，以确定气体剥离或星系相互作用是否是星系团中星系演化的主要物理机制。第二个项目是研究集群环境对集群核心AGN活动的影响。成像调查和光谱观测将确认类星体与宿主星团的关联，并确定其物理特性，如速度色散、气体含量和相互作用速率。

Ellingson, Erica AST 96-17145 Dr. Ellingson will investigate the effects of cluster environment on the star formation and AGN activity of galaxies at intermediate redshifts. The first project is a detailed spectroscopic and photometric study of 12 galaxies to determine whether gas stripping or galaxy interactions is the dominant physical mechanism for galaxy evolution in clusters. The second project is to investigate the effects of cluster environment on AGN activity in cluster cores. Imaging surveys and spectroscopic observations will confirm the association of quasars to host clusters and determine physical properties such as velocity dispersion, gas content and interaction rates.
