遭遇对Local Group类似物成员的影响。来自GALEX的观点
The impact of encounters on the members of Local Group Analogs. A view from GALEX
摘要：
星系演化探测器（GALEX）通过其远紫外和近紫外波段对本星系群模拟（LGA）LGG 225的明亮星系群进行了成像。一个显着的一部分组成员似乎经历了最近/正在进行的相互作用事件，强烈干扰整体星系形态。明亮的紫外线区域，伴随着强烈的尘埃灭绝的强烈恒星形成活动的场所，标志着星系外围形成不规则结构和尾巴。与本星系群相比，LGG 225似乎经历了一个更激烈和更活跃的进化阶段。
英文摘要：
The bright galaxy population of the Local Group Analog (LGA) LGG 225 has been imaged with the Galaxy Evolution Explorer (GALEX) through its Far- and Near-UV wavebands. A significant fraction of the group members appear to underwent recent/on-going interaction episodes that strongly disturbed overall galaxy morphology. UV-bright regions, sites of intense star formation activity accompanied by intense dust extinction, mark the galaxy outskirts forming irregular structures and tails. Compared to the Local Group, LGG 225 seems thus to be experiencing a more intense and active evolutionary phase.
