摘要

本文研究了52个早期型星系的中心强度比(CIR)的相关关系,其中包括24个椭圆星系和28个透镜状星系,这些星系来自附近(< 30 Mpc)宇宙的低密度环境。发现CIR与中心超大质量黑洞质量、中心速度色散、绝对B带星等、恒星凸起质量和宿主星系中心Mg2指数呈显著负相关。该研究提出使用CIR作为一种简单,快速和有效的光度测量工具来探索星系中存在的共同进化场景。

Study of central intensity ratio of early-type galaxies from low-density environment
We present correlations involving central intensity ratio (CIR) of 52 early type galaxies, including 24 ellipticals and 28 lenticulars, selected from low density environment in the nearby (< 30 Mpc) universe. CIR is found to be negatively and significantly correlated with the mass of the central super massive black hole, central velocity dispersion, absolute B band magnitude, stellar bulge mass and central Mg2 index of the host galaxy. The study proposes the use of CIR as a simple, fast and efficient photometric tool for exploring the co-evolution scenario existing in galaxies.
