Ukuqhuma kwe-Supernova, ukuhlanganiswa kwezinkanyezi ze-neutron kanye nezimbobo ezimnyama kubangela izenzakalo ezinamandla kakhulu eMkhathini - ukuqhuma kwe-gamma-ray, okubonwa eMhlabeni kuphela lapho kubanjwe emisebeni yawo. Ngo-Okthoba 2022, kwenzeka isigameko esingajwayelekile - ukuqhuma kwe-gamma ray okugqame kakhulu kuwo wonke umlando wokubhekwa, okubizwa nge-BOAT. Ukuqhuma kwaphuphuthekisa izinzwa ze-telescope, kodwa akuzange kuvimbele ukutholwa kwedatha, okwamangaza ososayensi - kwatholakala i-spectrum kuzo.
NgoLwesine, Julayi 25, 2024, kanyekanye ekuholeni Šø Izihloko ezimbili ezizimele zanyatheliswa emaphephandabeni esayensi, akhuluma ngokutholakala okumangalisayo okwabangela "ama-goosebumps" kososayensi. Ngokokuqala ngqa eminyakeni eminingi yokuqopha ukuqhuma kwe-gamma-ray, kwatholakala i-spectrum kuyo. Ngokuqondile, izimpawu ze-spectra zazikhona ekuqhumeni kwe-gamma-ray ngaphambili, kodwa zonke zachazwa ngokuphazanyiswa. Endabeni yomcimbi we-BOAT (inombolo yokubhalisa i-GRB 221009A), amathuba okubukeka kokuphazanyiswa esikhundleni se-spectrum alinganiselwa njengeyodwa kwezigidi ezingu-500 Ngamanye amazwi, kukhona zonke izizathu zokukholelwa ukuthi ososayensi bahlole imigqa ye-spectral okokuqala isikhathi njengengxenye yokuqhuma kwe-gamma-ray.
Ukuze uqonde, i-spectrum iyi-ins kanye nokuphuma kwe-physics kanye ne-chemistry yenqubo. Kusukela emigqeni yokumunca noma ekhanyayo, ungafunda okuningi mayelana nalesi simo, okuzokuvumela ukuthi ukhulume ngokuzethemba ngomsuka wokuqhuma kwe-gamma-ray ethile. Ososayensi abakakulungeli ukuqagela ngengqikithi yomcimbi we-BOAT noma "Brightest Of All Time", kodwa ukuqopha nokumodela kuzoqhubeka, futhi lokhu kuzoba yisisekelo somsebenzi kwezinye izinto ezifanayo.
Omunye usola ukuthi iqhaza elibalulekile kulokhu kutholwa okumangalisayo lenziwa ososayensi baseShayina kanye nesibonakude se-X-ray esizungezayo saseShayina i-GECAM-C. Ngesikhathi somcimbi we-BOAT, zonke izibonakude ze-gamma-ray zaphuphuthekiswa, kuhlanganise nethuluzi eliphambili le-NASA, i-Fermi. Ngokuya ngokuqina, ukuqhuma kwe-BOAT ngokwesilinganiso kwakugqame izikhathi eziyi-1000 kunokuqhuma okuvame ukurekhodwa. Izinzwa zesibonakude azikwazanga ukubekezelela lokhu, ngoba Izinzwa zesiShayina ze-GECAM-C, ebezikhutshazwe kancane noma zisethelwe ekuzweleni okuphansi. Ngenxa yedatha ye-GECAM-C, kube nokwenzeka ukwakha kabusha idatha ye-Fermi futhi kuhlukaniswe imigqa ye-spectral esignali.
Ngokokutholwe yiqembu lamazwe omhlaba lososayensi, ukukhishwa kwe-spectral kwathatha imizuzwana engaba ngu-40 futhi kwafinyelela amandla aphezulu angaba ngu-12 MeV, uma kuqhathaniswa ne-2 noma 3 MeV yokukhanya okubonakalayo. Ososayensi baseShayina baye baphinde baveza izingxenye ze-spectral ze-flare, bememezela ukutholakala komugqa we-gamma-ray onamandla afinyelela ku-37 MeV, abathi umugqa we-spectral wamandla ophezulu kakhulu owake wakhishwa into yasezulwini eMkhathini. Ngendlela, emcimbini we-BOAT sitholile . Itulo lihlala likhona. Kazi kungaba yini?
