Masana taurari da suka yi amfani da James Webb Space Telescope sun gano galaxy mai dauke da asalin wani fast radio burst mai nisa sosai. Rahoton NASA na ranar 8 ga Oktoba ya bayyana FRB 20240304B, wanda MeerKAT na Afirka ta Kudu ya fara ganowa a Maris 2024. Webb ya kara bayanan da rediyo kadai bai bayar ba.
Fast radio bursts sigina ne da ke wanzuwa na 'yan milliseconds. Ganin guda daya ba ya bayyana kai tsaye abin da ya samar da shi. Tawagar ta san wurin wannan sigina, amma manyan na'urorin kasa ba su iya ganin galaxy a wurin ba. Saboda haka suka nemi Webb ya duba.
Webb ya gano karamar galaxy kuma ya auna redshift, wato mikewar haske da ke da alaka da fadadar sararin samaniya. Sakamakon ya nuna lokacin da sararin samaniya yake da kusan shekaru biliyan uku. Galaxy din ta fi abin da masana suka zata kankanta, kuma tana samar da sabbin taurari.
Wannan matashin yanayi yana da muhimmanci idan ana kwatanta abubuwan da za su iya samar da sigina. Tsarin da yake bukatar dogon jinkiri sosai yana da wahalar daidaitawa da tarin matasan taurari. Saboda haka masana sun ce hadewar taurarin neutron biyu ba shi da yiwuwar bayyana wannan takamaiman sigina sosai.
Wani zabin shi ne matashin tauraron neutron mai karfin maganadisu, wanda ake kira magnetar. Bayanan sun dace da wannan yiwuwar a matakin farko, amma ba hoton magnetar yana samar da siginar ba ne. Haka kuma ba su tabbatar da cewa dukkan fast radio bursts suna da sanadi guda daya ba.
Sakamakon ya nuna amfanin hada lura ta rediyo da infrared. Sabbin ganowa za su iya gwada ko wasu sigina masu nisa suna fitowa daga irin wadannan galaxies. A yanzu an auna nisa kuma an fahimci yanayin wani dan gajeren al'amari sosai. Har yanzu ana binciken takamaiman tsarin da ya samar da shi.
