星系定向的一些观测问题

Some observational aspects of the orientation of galaxies

Wlodzimierz Godlowski

摘要:

我们研究了属于Tully星系群的星系样本。我们分析了星系群内星系的方位。我们没有发现显着偏离各向同性的方位角和角度$δ_D$和$η$给星系平面的空间取向。此外,我们还分析了不同的星系“真形”近似的结果,并指出了这一问题对星系空间取向研究的可能影响。讨论了所得结果对星系形成理论的意义。

英文摘要:

We investigated the sample of galaxies belonging to the Tully groups of galaxies. We analyzed the orientation of galaxies inside the group. We did not found significant deviation from isotropy both in orientation of position angles and angles $δ_D$ and $η$ giving the spatial orientation of galaxy planes. Moreover we analyzed consequences of different approximation of "true shape" of galaxies and showed possible influence of this problem for investigation of spatial orientation of galaxies. Implications of the obtained results for theory of galaxy formation was discussed as well.
