星系红移

基于神经网络的模板匹配方法求正常星系红移

Using Neural Networks Based Template Matching Method to Obtain Redshifts of Normal Galaxies

一种基于非线性降维求正常星系红移的新方法

A Novel Method for the Determination of Redshifts of Normal Galaxies by Non-Linear Dimensionality Reduction

离散时空和河外星系红移

Discrete space-time and red-shifts of galaxies

本文据此说明：河外星系红移是光子在其特征力场作用下的离散运动的直接结果。

This result suggests that the red-shifts of galaxies are direct results of photon motion in the discrete space-time under photon 's own force field .

同时对宇宙中物质大尺度结构探索中的新发现，例如宇宙长城、巨大吸引物、星系红移分布的周期性等，又对标准的宇宙学模型提出了严峻的挑战。

On the other hand , recent discoveries of the gigantic structures in the universe , such as the Great Wall , the Great Attractor and the periodic distribution of redshift of galaxies , seriously challenge the standard view of cosmic model .

活动星系核红移分布中的准周期峰

Quasi - periodical peaks in the redshift distribution of active galaxies

由一维流形上的红移分布数据，根据最近邻方法得到正常星系的红移值。

Finally , the NG redshifts are obtained by the nearest neighborhood technique from the redshift distribution on the manifold .

一旦测得星系的红移，我们便可开始重建恒星形成的历史了。

Once the redshifts of the galaxies have been measured , we can begin to reconstruct the history of star formation .

宇宙学家更倾向于红移的距离测量，计算宇宙的膨胀来判断光波被拉长了多少。这个星系的红移量大约是10.7。

In the cosmologist 's preferred distance measure of redshift , which gauges how much light has been stretched in an expanding universe , the galaxy lies at a redshift of about 10.7 .

他们发现了GR7星系——宇宙红移7号（CosmosRedshift7）的缩写，得名于追溯宇宙中遥远物体所使用的方法。

Galaxy CR7 - short for Cosmos Redshift 7 , after the method by which distant objects in the universe are dated - stood out .

Ⅰ类赛弗特星系与低红移弱射电类星体哈勃图的比较

于是天文学家就说星系的光「红移」了。

Astronomers say that the Galactic light has been redshifted .

第一章简要介绍相关的背景知识，包括结构形成和星系形成的理论模型、以及如何用星系红移巡天检验这些模型。

The first chapter provides a brief introduction to the relevant background knowledge , including theoretical models of structure formation and galaxy formation , and how to test these models using redshift surveys of galaxies .

此外，该图像部分的透镜星系出现红色-大的距离，这些星系的红移介绍，轮班其光红色部分频谱。

In addition the images of some of the lensed galaxies appear red & the large distance to these galaxies introduce redshift , which shifts their light to the red part of the spectrum .
