PAPAS: determine the actual SFR in red spirals falling into clusters

并不是所有的红色星系都是红色和死亡的。在不松弛的星团中--像室女座--也存在红色的螺旋，显示正在进行的星星形成，被尘埃变红。我们的目标是找出是否尘埃红色螺旋是共同的领域星系的过程中进入集群潜力或星星的形成是由冲压压力从跨集群间介质移动触发。在我们研究得最好的簇中，阿贝尔901/2从H和UV+FIR通量确定SFR导致矛盾的结果。利用红移到K波段的帕邢线进行了帕邢阿尔法巡天（PAPAS），以检验几个中等红移星系团的H基SFR。目前的建议应通过重复2016年下半年因恶劣天气而丢失的观测结果来完成A226/8的观测。

Not all red galaxies in clusters are red and dead. In unrelaxed clusters - like Virgo – also red spirals exist that show ongoing star formation, reddened by dust. We aim to find out whether the dusty red spirals are common field galaxies in the process of entering the cluster potential or whether their star formation is triggered by ram pressure from moving across the inter-cluster medium. In our best studied cluster, Abell 901/2 the determination of the SFR from H and the UV+FIR flux leads to conflicting results. The PAnic Paschen Alpha Survey (PAPAS) is proposed to check the H-based SFR in several intermediate redshift galaxy clusters by using the Paschen-line red-shifted into the K-band. The current proposal should complete the observations of A226/8 by repeating observations lost due to bad weather in H2016.
