Abstract

Some results are presented on studies of a sample of about hundred galaxies (“100SBS”) from two adjacent fields of SBS (Second Byurakan Survey), which have spectral data in SDSS (Sloan Digital SkySurvey-www.sdss.org ).The work is carried out as a part of the long-term program (Hakopian, 2013) forin-depth study of the galaxies in seven selected SBS fields (including the two under investigation).Comparative analysis was done between two classifications that the 100SBS objects got - from one side Starburst or Starforming in SDSS, from the other - SfGcont and SfGneb, with a possibility of further detailing in accordance to our scheme for SfG, i.e. star-forming galaxies. Obtained results showed good perspectives in using of our scheme for differentiation of activity phases of SfGs and for better statistics and comprehensive studies. Space distribution of 100SBS galaxies, what is important, homogeneously selected in continuous (32 sq.deg) area, was obtained using uniformly determined in SDSS redshift values. As it follows from the graphs plotted at 0.01 intervals the maximum of the distribution, with an equal number of Staforming and Starburst galaxies falls on the range 0.01

两个相邻SBS场中恒星形成星系样本的特征

本文介绍了对来自SBS(第二次比拉坎巡天)两个相邻区域的大约100个星系(“100SBS”)样本的研究结果，这些星系在SDSS(斯隆数字巡天-www.sdss.org)中有光谱数据。这项工作是长期计划(Hakopian, 2013)的一部分，该计划旨在深入研究七个选定的SBS领域(包括正在调查的两个领域)的星系。对100SBS天体的两种分类进行了比较分析——从SDSS中的Starburst或Starforming一侧，从另一侧- SfGcont和SfGneb，并可能根据我们的SfG方案(即恒星形成星系)进一步详细说明。所得结果对利用我们的方案进行SfGs活动阶段的区分以及更好的统计和综合研究具有良好的前景。在连续的(32平方度)区域内均匀选取100SBS星系的空间分布，使用SDSS红移值均匀确定。从图中可以看出，在间隔为0.01时，分布的最大值，同样数量的恒星形成星系和星暴星系落在0.01
