Qaraxyada Supernova, isku-darka xiddigaha neutron-ka iyo godadka madow waxay dhaliyaan ifafaalaha ugu tamarta badan caalamka - gamma-ray dilaac, kuwaas oo laga dareemo dhulka kaliya marka fallaadhoda la qabto. Bishii Oktoobar 2022, dhacdo aan caadi ahayn ayaa dhacday - gamma-ray-gii ugu iftiimay ee ka dillaacay dhammaan taariikhda indha-indheynta, oo loo yaqaan BOAT. Burburku wuxuu indho-tiray dareemayaasha telescope-ka, laakiin ma aysan ka hortagin soo kabashada xogta, taas oo noqotay mid la yaab leh saynisyahannada - muuqaal ayaa laga helay iyaga.
Khamiista, Luulyo 25, 2024, isku mar ayaa hogaaminaya и Laba maqaal oo madaxbannaan ayaa lagu daabacay joornaalada sayniska, kuwaas oo ka hadlay daahfurka cajiibka ah ee sababay "goosebumps" saynisyahano. Markii ugu horreysay sannado badan oo duubis ah oo dillaacay gamma-ray, waxaa laga helay spectrum. Si sax ah, calaamadaha spectra-yadu waxay ku jireen qarxinta gamma-ray ka hor, laakiin dhammaantood waxaa lagu sharraxay faragelin. Xaaladda dhacdada BOAT (lambarka diiwaan gelinta GRB 221009A), suurtogalnimada muuqaalka faragelinta halkii laga heli lahaa spectrum ayaa lagu qiyaasay mid ka mid ah 500 milyan Si kale haddii loo dhigo, waxaa jira sabab kasta oo lagu aamino in saynisyahannadu ay baareen xariiqyo muuqaal ah waqti qayb ka mid ah dilaaca gamma-ray.
Si loo fahmo, spectrum-ku waa ka-soo-baxyada fiisigiska iyo kimistariga habka. Laga soo bilaabo xariiqyada nuugista ama iftiinka, waxaad wax badan ka baran kartaa ifafaale, kaas oo kuu ogolaanaya inaad si kalsooni leh uga hadasho asalka qarax gamma-ray gaar ah. Saynis yahanadu wali diyaar uma aha inay ka fikiraan nuxurka BOAT ama dhacdada "Brightest of All Time", laakiin dejinta iyo qaabaynta ayaa sii socon doonta, tani waxay noqon doontaa saldhigga shaqada ee dhacdooyinka kale ee la midka ah.
Mid ka mid ah waxa laga shakisan yahay in wax weyn ku soo kordhinta daahfurkan cajiibka ah ay sameeyeen saynisyahano Shiinees ah iyo telescope-ka Shiinaha ee GECAM-C ee ku wareegaya X-ray. Wakhtiga ay dhacaysay dhacdada BOAT, dhammaan telescopes-yada gamma-ray-ga waa la indho tiray, oo ay ku jiraan aaladda calanka ee NASA, Fermi. Marka la eego xoojinta, dillaaca BOAT ayaa celcelis ahaan 1000 jeer ka iftiin badnaa qaraxyadii la diiwaan geliyey. Dareemayaasha telescope-yadu way xamili waayeen tan, waayo Shiinees GECAM-C, kuwaas oo qayb ahaan naafo ahaa ama lagu dejiyay dareen hoose. Thanks to xogta GECAM-C, waxaa suurtagashay in dib loo dhiso xogta Fermi oo laga sooco xadhkaha muuqaalka ah ee calaamada.
Sida laga soo xigtay natiijooyinka koox saynisyahano caalami ah, qiiqa muuqaalku wuxuu socday ilaa 40 ilbiriqsi wuxuuna gaadhay tamarta ugu sarreysa ee ku saabsan 12 MeV, marka la barbar dhigo 2 ama 3 MeV ee iftiinka muuqda. Saynis yahano Shiineys ah ayaa sidoo kale tilmaamay qaybaha muuqaalka ee dabka, iyaga oo ku dhawaaqay in la helay xariiqda gamma-ray oo tamar gaadhaysa 37 MeV, taas oo ay ku andacoonayaan in uu yahay xariiqda tamarta ugu sareysa ee abid uu sii daayo shayga samada ee Koonka. By habka, in dhacdada BOAT aan ka helnay . Dhagartii baa hadhay. Waxaan la yaabanahay waxa ay noqon kartaa?
