Poyasnenie: Ellipticheskaya galaktika NGC 7600 po razmeru ochen' pohozha na Mlechnyi put', ona nahoditsya na rasstoyanii 150 millionov svetovyh let ot nas. Na etom glubokom snimke, ohvatyvayushem oblast' neba razmerom v polgradusa v sozvezdii Vodoleya, mozhno uvidet' zamechatel'noe galo i vlozhennye drug v druga obolochki, okruzhayushie galaktiku NGC 7600. Takie intersnye osobennosti struktury mozhno ob'yasnit' akkreciei temnoi materii i zvezd v techenie kosmologicheskogo vremeni. Komp'yuternoe modelirovanie obrazovaniya galaktik v ramkah kosmologicheskoi modeli s holodnoi temnoi materiei, pomogayushei formirovaniyu galakticheskih galo, s porazitel'noi detal'nost'yu vosproizvodit stroenie galaktiki NGC 7600. Zamechatel'nyi video-rolik s simulyaciei formirovaniya galaktiki mozhno posmotret' na resurse Vimeo, a takzhe on dostupen v drugih formatah. Eto ubeditel'no dokazyvaet, chto tonkaya struktura razlichnyh vzaimodeistvuyushih galaktik, nablyudaemyh s Zemli v nebol'shie shirokougol'nye teleskopy, yavlyaetsya pryamym sledstviem processa formirovaniya galaktik i fundamental'nyh svoistv temnoi materii.
