Summary
| Description |
English: 3C295 (Cl 1409+524) is one of the most distant galaxy clusters observed by X-ray telescopes. The cluster is filled with a vast cloud of fifty million degree gas that radiates strongly in X rays. It has a redshift of 0.461, which means that we see the galaxy cluster as it was 4.7 billion years ago. 3C295 was first discovered as a bright source of radio waves. The source of the radio emission was found to be a giant elliptical galaxy located in the center of the cluster of galaxies. Chandra discovered that this central galaxy is a strong, complex source of X rays.
Русский: 3C 295 (Cl 1409+524) - один из наиболее удалённых галактических кластеров, наблюдаемых рентгеновскими телескопами. Кластер заполнен многочисленными облаками газа, разогретых до температур в 50 млн градусов и излучающих мощные рентгеновские лучи. Он имеет красное смещение 0,461, т.е. мы видим кластер таким, каким он был 4,7 млрд. лет назад. 3C 295 впервые был открыт как яркий источник радиоволн. Позже выяснили, что источником радиоизлучения является гигантская эллиптическая галактика расположенная в центре кластера галактик. Телескоп «Чандра» обнаружил, что эта центральная галактика также является и мощным, составным источником рентгеновского излучения. |
