| 초록 | We study the environmental dependence of the mass-size relation for the most massive early type galaxies (M gt; $10^{10.7}M_{ odot}$ ) in the redshift range 0.10~0.15. The sizes of galaxies are measured by non-parametric method. We find that galaxies more massive than $10^{11.1}M_{ odot}$ show the environmental dependence in the mass-size relation. The galaxies with M gt; $10^{11.1}M_{ odot}$ located in the densest, cluster like environment have larger sizes and extended surface brightness profiles than their counterparts located in a low dense environment. We also find that the environmental dependence of the mass-size relation is more significant for the brightest cluster galaxies (BCGs) than non-BCGs. We use the semi analytic galaxy formation simulation based on the Millennium 1 Simulation for interpretation. Our result can be explained with a hierarchical growth of the most massive galaxies through dissipation-less merger in dense environment. |
