Poyasnenie:
Skoplenie galaktik Gidra A deistvitel'no sovershenno gigantskoe.
Takie
skopleniya galaktik predstavlyayut soboi samye krupnye gravitacionno
svyazannye ob'ekty vo Vselennoi.
Otdel'nye galaktiki slishkom holodnye, chtoby ih
mozhno bylo razglyadet' na etom
rentgenovskom izobrazhenii, poluchennom observatoriei Chandra i
predstavlennoi v uslovnyh cvetah. Pokazano, kak skoplenie Gidra A
naskvoz' pronizyvaet gaz temperaturoi 40 millionov gradusov.
Na osnove issledovanii byl sdelan vyvod, chto takie
oblaka goryachego v rentgenovskom smysle gaza
yavlenie dostatochno obshee dlya
skoplenii galaktik.
Schitaetsya, chto gaz,
postepenno pronikaya, budet ohlazhdat' central'nye oblasti skoplenii, tak chto
budut obrazovyvat'sya novye galaktiki i zvezdy.
Odnako vmesto etogo izobrazhenie Chandry demonstriruet to, chto okolo yarkogo yadra
skopleniya magnitnoe pole i vzryvnye processy vozmushayut spokoinoe techenie,
tak chto potok izgibaetsya v petli i dlinnye struktury. Eto, v svoyu ochered', dolzhno
tormozit'
obrazovanie zvezd i galaktik vnutri skopleniya.
