论文摘要
我们提出了涉及52个早期星系中心强度比（CIR）的相关性，其中包括24个椭圆形和28个凸耳，从附近的低密度环境（<30 mpc）宇宙中选择。发现CIR与中央超质黑洞，中央速度分散体，绝对B带量，恒星凸起质量和宿主星系中心MG2指数呈负相关。该研究建议将CIR用作简单，快速，高效的光度工具，用于探索星系中存在的共同进化方案。
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.
