Yeruusaalem, 15 Oktoobar, 2025 (TPS-IL) — Dhakhaatiirta xiddigaha ee Israa’iil iyo Maraykanka ayaa ogaaday in daloolada madow ay ka firfircoon yihiin sidii hore loo malaynayay, isla markaana ay dib u bilaabi karaan hawshooda ka dib markii ay u muuqdeen kuwo deggan, sidaas waxaa ku dhawaaqday Jaamacadda Cibraaniga arbacadii. Helitaankan waxaa ka dhashay indha-indhayntii ugu horreysay ee dalool madow oo aad u weyn oo burburinaya xiddig ka fog xarunta galax-ka, taasoo soo saartay calaamado raadiyo oo aad u dhalaalaya oo si degdeg ah isu beddelaya. Helitaankan wuxuu caqabad ku yahay mala-awaalkii hore ee ku saabsanaa halka ay ku yaallaan daloolada madow iyo sida ay u dhaqmaan.
“Tani waa wax aad u yaab leh,” ayuu yiri Dr. Itai Sfaradi oo ka socda Jaamacadda California, Berkeley, oo ah qoraaga ugu weyn ee daraasadda. “Marnaba horay uma aragno qiiqa raadiyaha oo aad u dhalaalaya oo ka yimid dalool madow oo burburinaya xiddig, fog ka fog xarunta galax-ka — oo si degdeg ah isu beddelaya. Waxay beddeshaa sida aan uga fikirno daloolada madow iyo dhaqankooda.”
Daraasadda, oo lagu daabacay majaladda la qiimeeyay ee The Astrophysical Journal Letters, waxaa hoggaaminayay Sfaradi iyo Prof. Raffaella Margutti oo ka socda UC Berkeley, iyadoo ay ka qayb galeen khuburo ka socda hay’addo caalami ah, oo ay ku jiraan Prof. Assaf Horesh oo ka socda Jaamacadda Cibraaniga ee Yeruusaalem. Dhacdada, oo loo bixiyay “AT 2024tvd,” waxay ka dhacday qiyaastii 2,600 sano oo iftiin ka fog xarunta galax-ka ay degganayd.
“Tani waa mid ka mid ah helitaannada ugu xiisaha badan ee aan ka qayb qaatay,” ayuu yiri Horesh. “Xaqiiqda ah in uu hoggaaminayay ardaygii hore ee aan macallinka u ahaa, Itai, ayaa ka dhigaysa mid ka sii macno badan. Waa guul kale oo cilmiyeed oo Israa’iil dhigaysa meesha ugu horreysa ee cilmiga xiddigaha caalamiga ah.”
Indha-indhaynta laga helay telescope-yada raadiyaha ee ugu waaweyn — oo ay ku jiraan Very Large Array ee New Mexico, ALMA ee Chile, Allen Telescope Array ee California, Submillimeter Array ee Hawaii, iyo AMI-LA ee UK — waxay muujiyeen laba iftiin oo raadiyo oo kala duwan oo si ka degdeg badan oo kasta oo dhacdo burburinta xiddigaha ah oo la arkay. Xogta waxay soo jeedinaysaa in daloolka madow uu soo saaray qiiq xooggan bilooyin ka dib burburkii xiddigta, taasoo muujinaysa in daloolada madow ay dib u “soo toobi karaan” si ku meel gaar ah ka dib muddooyin degganaan ah.
Helitaannada waxay leeyihiin saameyn muhiim ah oo ku aaddan fahamka horumarka galax-yada iyo dhaqanka daloolada madow. Galax-yada waxaa ku jiri kara daloolo madow oo aad u waaweyn oo wareegaya ama meel ka fog meeshooda, isla markaana hababka ay kuwoodan cosmic-ka ahi u tuuraan maadada ayaa noqon kara kuwo ka adag oo dib u dhacsan sidii hore loo malaynayay.
“Helitaankan wuxuu furayaa daaqad cusub oo ku saabsan sida ay daloolada madow ula falgalaan hareeraha,” ayuu yiri Sfaradi. “Waxay noo sheegaysaa in caalamku ka firfircoon yahay sidii aan u malaynaynay, isla markaana aan laga yaabo inaan hoos u dhigeyno halka iyo sida ay u shaqeeyaan bahalladan.”
