Tani cusub image NASA / ESA Hubble Space xoqad muujinaysaa Galaxy qurux badan loogu aarayo loo yaqaan PGC 54493, oo ku yaalla shir tagayso ee Serpens (Abeesadii). Galaxy Tani waa qayb ka mid ah cluster Galaxy ah oo uu soo bartay by cirbixiyeyaasha sahaminta arrin xiiso yaqaan lensing gravitational daciif ah.
Saamayn Tani, keena qaybinta si aan loo sineyn ee arrinta (oo ay ku jirto arrinta madow) Caalamka oo dhan, ayaa inta laga hubsanayo via sahan sida ay Hubble Dhexdhexaad Deep Survey. Arrinta Dark waa mid ka mid ah waxyaalaha qarsoon weyn ee cosmology. Waxay u dhaqmo si kala duwan uu ka soo arrinta caadiga ah sida aysan u bixiya ama nuugo iftiin ama noocyada kale ee tamarta electromagnetic - sidaa muddada “madow.”
Waxaan Inkasta oo aan si toos ah u arki karaan arrin mugdi ah, waxaan ognahay waxa ka jira. Mid ka mid ah xabbad wax garadka cadayn u ah jiritaanka arintan dahsoon loo yaqaanaa “Dhibaatada warejin Galaxy.” Galaxies isku shaandheyn xawaare sida iyo hab in arrin caadi ah oo keliya sida - alaabtii aan u arko - ma noqon doono in ay iyagii ku soo wada qaban karo. Inta ay mass in uu yahay “seegay” muuqata waa arrin mugdi ah, taas oo la rumeysan yahay ilaa sameeyo qaar ka mid ah 27 boqolkiiba oo ka mid ah waxyaabaha guud ee Caalamka, tamarta madow iyo arrin caadi ah ka dhigaan ilaa inta ka hartay. PGC 55493 ayaa lagu soo bartay oo xidhiidh la leh saamayn loo yaqaan adhijirrada runtan. Tani waa dhaqan lensing daciif ah gravitational in abuuraa dhabtii yaryar oo ku yaala images of galaxies fog.
