Ultradiffuse galaxies found in deep HST images of HFF

We present the detection of a large population of ultradiffuse galaxies (UDGs) in two massive galaxy clusters, Abell S1063 at z=0.348 and Abell 2744 at z=0.308, based on F814W...本研究报道了基于F814W波段相关数据，在两个大质量星系团——红移z=0.348的阿贝尔S1063（Abell S1063）与红移z=0.308的阿贝尔2744（Abell 2744）中，探测到大量超弥散星系（ultradiffuse galaxies, UDGs）的相关发现。
