星系盘厚度效应的研究

The Thickness Effect of Galactic Disk

银河系星系盘的直径约为1.4万光年。

The disk boasts a diameter of about 14000 light years .

这些结论为晚型星系盘的形成和演化模型提供了进一步的约束。

These conclusions provide farther constrains to the formation and evolution model of disk of spiral galaxies .

这张地图显示，银河系的星系盘远非平面状，而明显是弯曲的，且各处厚度不一，距离星系中心越远处越厚。

The map showed that the galaxy 's disk , far from flat , is significantly warped and varies in thickness from place to place , with increasing thickness measured further from the galactic center .

天文学家通过追踪遍布银河系的数千颗大的脉动变星，绘制出了迄今为止最精确的银河系地图。从地图上看，由无数恒星组成的星系盘并非扁平，而很明显是弯曲的、扭曲的。

Astronomers have created the most precise map to date of the Milky Way by tracking thousands of big pulsating stars spread throughout the galaxy , demonstrating that its disk of myriad stars is not flat but dramatically warped and twisted in shape .

研究人员于上周四公布了一张银河系的三维地图，其中包括太阳在内共有1000多亿颗恒星。这张地图全面展示了银河系结构：由四个大的螺旋型枝节和一个条状的核心区域组成的星系盘。

The researchers on Thursday unveiled a three-dimensional map of the Milky Way - home to more than 100 billion stars including our sun - providing a comprehensive chart of its structure : a stellar disk comprised of four major spiral arms and a bar-shaped core region .

Its strong gravitation attracts the surrounding ether and planets to collapse toward it , creating the disc-shaped structure of a galaxy .

简要地评述了活动星系核中吸积盘与喷流存在内在联系的观测证据，及中央黑洞与活动星系核的射电辐射特征的关系。

The observational evidence on the disk-jet connection in active galactic nuclei and the correlation between the central black holes and their radio properties are summarized .

科学家认为此过程解释了为什麽在年轻恒星周围会形成原生行星盘，或许也能解释在星系中心，气体盘如何与黑洞结合。

Scientists believe this process explains how protoplanetary disks form around young stars and perhaps how gas disks coalesce around black holes at the centers of galaxies .

用一个星系相互作用数值模拟的综合三体模型，研究椭圆星系是否由盘星系合并而成。

Perfect three-body model is used in the numerical simulation of interacting galaxies for studying whether merging disk galaxies make elliptical galaxy .
