  redshift
The optical object is brighter in V than it is in B and has an extended structure, which we interpret as intense Lyα line emission with redshift z≈3.5 and a continuum depression in the adjacent short-wavelength region.
      
The flux rise in these lines was accompanied by a redshift of the intensity peak in the profiles by~50 km s-1.
      
HD molecular lines in an absorption system at redshift z=2.3377
      
(2000), we identified HD molecular lines in an absorption system at redshift z=2.3377.
      
As far as we know, this is the first detection of HD molecules at high redshift.

In this paper a statistical investigation has been made on the redshift-magnitude relation of quasars with radio components structure. The main results are sum-marized in the following way: 1. The largest distance D between components is an important parameter which can be employed to classify the “standard candle”. 2. Seeing that the regression equations with high correlation coefficient among redshifts, apparent magnitude and D have been established, it may be true that the redshift of these quasars...

In this paper a statistical investigation has been made on the redshift-magnitude relation of quasars with radio components structure. The main results are sum-marized in the following way: 1. The largest distance D between components is an important parameter which can be employed to classify the “standard candle”. 2. Seeing that the regression equations with high correlation coefficient among redshifts, apparent magnitude and D have been established, it may be true that the redshift of these quasars is mainly cosmological. 3. It has been found that the redshift-distance relation may be expressed as r∞z-0.19z~2 which departs apparently from Hubble’s linear relation in the range of Z>1. 4. The redshift-magnitude relation given by the new redshift-distance relation looks better than Hubble’s for radio galaxies as well. 5. The optical luminosity of quasars decreases as the value of D inereases.

本文对有射电子源结构类星体的红移、视星等关系进行了统计研究。主要结果如下: 1.最大子源间距D是个重要的参量,可以用它进行“标准烛光”分类。 2.由于红移,视星等及D之间存在着相关系数较高的回归关系,所以,这种类星体的红移可能主要是宇宙学的。 3.红移与距离的关系是r∝z-0.19z~2,在z>1时与哈勃线性关系有明显偏差。 4.对于射电星系,这个红移距离关系所给出的视星等红移关系也比哈勃关系为好。 5.随着子源间距的增大,类星体的光学光度逐渐下降。

Based upon our first paper and continuing the "Standard candle" classification by use of the component linear distance D, we attain to the following statistical correlation of some type of Quasars with largest angular diameter Q_(max): the correla- tion between visual magnitude and redshift; the correlation between its absolute magnitude, radio-luminosity of single frequency, integral radio Iuminosity, colour in- dex difference Q and D. According to these statistical laws, a series of inferrences on the...

Based upon our first paper and continuing the "Standard candle" classification by use of the component linear distance D, we attain to the following statistical correlation of some type of Quasars with largest angular diameter Q_(max): the correla- tion between visual magnitude and redshift; the correlation between its absolute magnitude, radio-luminosity of single frequency, integral radio Iuminosity, colour in- dex difference Q and D. According to these statistical laws, a series of inferrences on the evolution prop- erties have been derived as follows: 1. The optical luminosity decreases with the increase of D. dM_v/dD=10.~m6/MPC. 2.The radio luminosity decreases with the increase of D. dM_(4,8-5000)=9.~m17/MPC. 3.The colour index difference Q decreases with the increase of D. dQ/dD=-1.~m55/MPC. 4.In the process of evolution, radio spectral type, defined by the spectral in- dex, does not change in general. 5. Optical radiation is mainly lion-thermal, but thermal radiation increases gra- dually with evolution. 6.The time scale estimated from optical luminosity, radio luminosity and col- our index difference Q, all have nearly the same value, 1.6 10~7 yr. 7. There is no discrepancy between the above features and the viewpoint that QSO_s evolve to galaxies. 8.There is no apparent statistical dependence between D and the distance, i. e. no evidence to, imply that all QSO_s were formed at the same epoch. This is con- trary to the views of the bigbang cosmology.

本文在第I部分的基础上,继续用类星体射电子源线距D进行“标准烛光”分类,经过统计分析,得到了子源角径最大的一类类星体的一些统计规律:它的视星等与红移之间,它的绝对星等、单频射电光度、积分射电光度和色指数差Q与D之间有很好的相关性等.由此得到下列有关有子源类星体演化性质的推论:1.随着子源间距D的增大,光学光度下降:dM_v/d_D=10.~m6/MPC.2.随着子源间线距D的增大,射电光度下降.dM_(408-5000)/dD=9.~m04/MPC.3.随着子源间线距D的增大,色指数差Q下降.dQ/dD=-1.~m55/MPC.4.在演化过程中,射电谱型,即谱指数基本保持不变.5.光学辐射主要是非热致的.但随着演化,热致辐射的成分渐渐增多.6.根据光学光度、射电光度以及色指数差Q三种物理量所估计的类星体的演化时标基本一致,大约是1.6×10~7年.7.这些性质和类星体最后演化为星系的总观点不矛盾.8.子源线距D与距离间没有明显的统计相关,即没有迹象表明类星体是在同一个时代产生的,这是大爆炸宇宙学所不能解释的.

The distribution of redshifts and magnitudes of over 630 QSO's is analyzed statistically by x2-test, and it is shown that the redshift distribution of QSO's is significantly anisotropie, while the QSO's magnitude distribution appears isotropio.

本文用x2检验法对630多个类星体的红移分布和星等分布进行了统计分析.结果表明,尽管类星体的星等分布表现为各向同性结构,但它们的红移分布的非各向同性是统计显著的.
