El Isibonakude se-ALMA esikhathini esifushane isibe ngesinye sezikhali ezifiseleka kunazo zonke izazi zezinkanyezi emhlabeni ngenxa yamandla namandla. Ngenxa yamathuba ahlinzekwa yileli thuluzi, iqembu lezazi zezinkanyezi likwazile ukuthola umoya-mpilo endaweni ekude kakhulu ethathwe yiteleskopu, le ntokazi Umthala A2744_YD4.
Esinye sezici eziyinhloko zalo mthala okude ukuthi, ngokumangala kwabaphenyi, uqukethe inani elikhulu lokuqina, okuthile okungahle kube ngumphumela wokufa kwesizukulwane sangaphambilini senkanyezi esidala nesibaluleke kakhulu. Lo thuli, lona, ikakhulukazi lwakhiwe ngezinto ezinjenge-silicon, i-carbon ne-aluminium, izinto ezikhona ezinhlamvini ezincane zosayizi wesigidi esisodwa sentimitha.
UNicolas Laporte nethimba lakhe bathola umoya-mpilo we-ionized emthaleni u-A2744_YD4.
Njengoba kuchaziwe UNicolas Laporte, umcwaningi e-University of London kanye nenhloko yethimba elenze lokhu kutholakala:
I-A2744_YD4 akuyona kuphela imithala ekude kakhulu ebonwe yi-ALMA, kepha ukutholwa kothuli olungaka kukhombisa ukuthi lo mthala wawusungcolisiwe yi-supernovae yakuqala. Itholakala emthaleni osuvele waziwe owaqala lapho umkhathi wawungamaphesenti amane kuphela enkathi okuyo njengamanje.
Lolu cwaningo lwenze kwaba nokwenzeka ukuthola ukukhishwa okukhazimulayo komoya-mpilo we-ionized, okuwavumele bheka i-galaxy njengoba kwakunjalo lapho umkhathi wawuneminyaka engaba yizigidi ezingama-600 ubudala, umzuzu lapho kwakhiwa izinkanyezi nemithala yokuqala. Ngokusho kokuqagela okwenziwe ngemuva kwezifundo, kubonakala sengathi umthala ubuzoqukatha uthuli olulingana nezikhathi eziyizigidi eziyisithupha ubukhulu beLanga.
