z>0.3的射电星系表。III:根据NVSS数据的角尺寸和通量密度

Catalog of Radio Galaxies with z>0.3. III: Angular Sizes and Flux Density According to the NVSS Data

M. L. Khabibullina, O. V. Verkhodanov

摘要:

我们描述的程序建设的样本遥远($z>0.3$)的射电星系使用NED,CATS和SDSS数据库进一步使用在各种统计检验。我们相信样本中没有具有类星体性质的物体。本文是我们计划用于宇宙学检验的射电星系表描述的第三部分。本文报道了NVSS巡天表天体角大小的抽样结果及其初步统计分析。构造了“角尺寸-红移-通量密度”和“角尺寸-红移-光谱指数”三参数图及其双参数投影。在“源大小-通量密度”图中,射电星系的三个子样本被分开。

英文摘要:

We describe the procedure of the construction of a sample of distant ($z>0.3$) radio galaxies using the NED, CATS and SDSS databases for further use in various statistical tests. We believe the sample to be free of objects with quasar properties. This paper is the third part of the description of the radio galaxies catalog that we plan to use for cosmological tests. We report the results of the sample of angular sizes for the NVSS survey list objects, and its preliminary statistical analysis. Three-parameter diagrams "angular size-redshift-flux density" and "angular size-redshift-spectral index", and their two-parameter projections are constructed. Three subsamples of radio galaxies are separated in the "source size--flux density" diagram.
