Abell 2667 is a galaxy cluster. It is one of the most luminous galaxy clusters in the X-ray waveband known at a redshift about 0.2. This cluster is also a well-known gravitational lens. On 2 March 2007, a team of astronomers reported the detection of ''comet galaxy'' in this cluster. 〔(Scientific paper by Luca Cortese, Delphine Marcillac, Johan Richard and collaborators )〕 This galaxy is being ripped apart by the cluster’s gravitational field and harsh environment. The finding sheds light on the mysterious process by which gas-rich spiral-shaped galaxies might evolve into gas-poor irregular- or elliptical-shaped galaxies over billions of years. ==See also== * Abell catalogue * Comet Galaxy * List of Abell clusters * X-ray astronomy 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Abell 2667」の詳細全文を読む スポンサード リンク
