Ua ʻike ʻia ka telescope eROSITA i ka makahiki 2019 i ʻelua mau ʻōpuʻu X-radiation-emitting bubbles, ʻo kēlā me kēia ma kahi o 36.000 mau makahiki māmā ke kiʻekiʻe a me 45.600 mau makahiki kukui ākea, ma luna a ma lalo o ke kikowaena o kā mākou huila Milky Way. Ua like loa kēia mau ʻōhū me nā mea ʻē aʻe ʻelua i loaʻa e kekahi hale kiaʻi gamma-ray, ʻo Fermi, he ʻumi makahiki ma mua. He ʻano liʻiliʻi, me he mea lā ua moni ʻia.
He aha ka mea i hiki ke kumu i kēia mau lua pilikua a hiki i kēia manawa he mea pohihihi. Akā, ʻo ko lākou ʻano like me ka nui a me ke ʻano e hōʻike ana ua kipaku ʻia lākou e ka hanana cataclysmic like, kahi mana weliweli o ka ikehu e hū mai ana mai ke kumu o kā mākou galaxy. he haʻawina hou
i paʻi ʻia ma ka 'Nature Astronomy' e kekahi hui honua e hōʻike ana ʻo nā ʻōhū ka hopena o ka jet ikaika o ka ikehu i hana ʻia e Sagittarius A*, ka lua ʻeleʻele nui ma ke kikowaena o ka Milky Way. Ua hoʻomaka ia e hoʻokahe i nā mea ma kahi o 2,6 miliona mau makahiki i hala a ʻike ʻia ma kahi o 100.000.
"He mea koʻikoʻi kā mākou mau hopena ma ke ʻano he mea pono e hoʻomaopopo i ke ʻano o ka hui ʻana o nā mea kilokilo ʻeleʻele me nā galaxies ma kahi āu e noho ai, no ka mea, ʻo kēia ka launa pū ʻana e hiki ai i kēia mau mea kilokilo ʻeleʻele ke hana i kahi ʻano hoʻomalu i ka mālamalama o ka [ulu] ʻole ʻia" wahi a Mateusz Ruszkowski, he kilo hōkū ma ke Kulanui o Michigan a he mea kākau pū o ka noiʻi.
ʻElua mau hiʻohiʻona hoʻokūkū e wehewehe ana i nā ʻōhū Fermi a me eRosita. ʻO ka mea mua e hōʻike ana e hoʻokele ʻia ka puka ʻana e kahi nuklea, kahi e pahū ai kahi hōkū i kahi supernova a kipaku aku i nā mea. ʻO ke kumu hoʻohālike ʻelua, ka mea i kākoʻo ʻia e ka hui, e hōʻike ʻia ana kēia mau kahe i waho e ka ikehu i hoʻokuʻu ʻia mai ka lua ʻeleʻele supermassive ma ke kikowaena o kā mākou galaxy.
hana i hala
He mau mea hoʻokahi nā puka ʻeleʻele, nui loa ʻaʻole hiki i ka mālamalama ke pakele. Eia nō naʻe, ke hoʻopiha ʻia nā puka ʻeleʻele i nā mea mai ko lākou puni, hiki iā lākou ke hana i nā lua o nā mea e pana ana i nā ʻaoʻao ʻē aʻe i ka wikiwiki relativistic, kahi hapa nui o ka māmā o ka māmā. Wahi a ke kumu hoʻohālike i hana ʻia e ka poʻe astronomers, ua lōʻihi kēia mau mokulele ikaika loa ma kahi o 100.000 mau makahiki. Ua hoʻopili ʻia a hiki i ka 10,000 manawa o ka nui o ka Lā i kēia manawa.
Makemake ka poʻe Astronomers i ka nānā ʻana i kēia mau ʻōhū no ka mea aia lākou i loko o ko mākou pā hale galactic e kū'ē ana i nā mea i loko o ka galaxy ʻokoʻa a i ʻole ma kahi mamao o ka cosmological. ʻO ka loaʻa ʻana o nā ʻōhū e hōʻike ana he ʻoi aku ka ikaika o Sagittarius A* i ka wā i hala ma mua o kona mālie i kēia manawa. Hāʻawi kēia mau hana i nā mea noiʻi i ka ʻike waiwai e pili ana i ka ulu ʻana o ka lua ʻeleʻele supermassive a me ka galaxy i ko lākou nui o kēia manawa. Hiki ke hoʻohana ʻia nā ʻike e ʻike inā aia nā ʻōhū like ma nā galaxies ʻē aʻe.
