摘要:

在这一过程中,我们期待在早期类型的星系从哈勃太空望远镜成像和它们的整体运动学观测与SAURON积分场摄谱仪的光度核属性之间的关系。我们比较内部的光度配置文件和慢/快旋转类,定义的幅度的一个新定义的LambdaR参数,表明慢旋转往往是更大规模的系统,并显示较浅的内部配置文件和快速旋转步进的。然而,值得注意的是,这两个光度组和运动学组之间并不存在一对一的关系。

英文摘要:

In this proceeding we look at the relationship between the photometric nuclear properties of early-type galaxies from Hubble Space Telescope imaging and their overall kinematics as observed with the SAURON integral-field spectrograph. We compare the inner slope of their photometric profiles and the Slow/Fast rotator classes, defined by the amplitude of a newly defined LambdaR parameter, to show that slow rotators tend to be more massive systems and display shallower inner profiles and fast rotators steper ones. It is important to remark, however, that there is not a one-to-one relationship between the two photometric and kinematic groups.
