论文摘要
我们研究了珀尔修斯群集中的星系种群，该山脉大致涵盖了簇的病毒半径。在B和H alpha中的Schmidt CCD图像上选择了星系，并与SDSS图像结合使用。我们提供了1294个星系的目录。从“眼球”检查中获得了90％的星系的形态学信息，部分得到了表面亮度分析的支持。红移取自SDS，文献来源和自身的光谱观测，可用于24％的目录星系。银河系目录用于得出簇特性，例如径向谱，亚构架，病毒质量和病毒半径的指示，并就形态类型和特征性，星形形成率和主动银河系核研究簇星系人群。除了统计方法外，我们还简要介绍了具有显着形态特征性的18个星系星系的个人描述。 （摘要修改以匹配Arxiv格式。）
We investigate the galaxy population in a field of the Perseus cluster that roughly covers the virial radius of the cluster. The galaxies were selected on Schmidt CCD images in B and H alpha in combination with SDSS images. We present a catalogue of 1294 galaxies. Morphological information was obtained for 90% of the galaxies from the `eyeball' inspection, partly supported by the surface brightness profile analysis. Redshifts were taken from SDSS, literature sources, and own spectroscopic observations and are available for 24% of the catalogues galaxies. The galaxy catalogue is used to derive cluster properties, such as radial profiles, indications of sub-structure, virial mass, and viral radius and to study the cluster galaxy population with regard to morphological types and peculiarities, star formation rates and active galactic nuclei. In addition to the statistical approach, we present brief individual descriptions of 18 cluster galaxies with conspicuous morphological peculiarities. (Abstract modified to match the arXiv format.)
