矮星系内容和附近星系群演化状况的检验
Testing of the dwarf galaxy content and the evolutionary status of nearby groups of galaxies
摘要:
我们在五个松散的星系群中进行了矮星系的视觉和参数搜索。使用HET进行的后续光谱学检查显示,形态选择的成功率为50%。这些星系群的演化状态各不相同:NGC 6962星系群有一个部分松弛的核心,周围有一个陷落区,而NGC 5005/5033星系群和IC 65星系群,它们只由晚型星系组成,可能仍在聚集。
英文摘要:
We carried out visual and parametric searches for dwarf galaxies in five loose groups of galaxies. Follow-up spectroscopy with the HET has shown a 50% success rate of morphological selection. The evolutionary status of the studied groups differs: while the NGC 6962 group has a partially relaxed core, surrounded by an infall region, the NGC 5005/5033 group and the IC 65 group, which consist only of late-type galaxies, are probably still assembling.
