Mumufananidzo mutsva wepakati-infrared wakatorwa neJames Webb Space Telescope, iyo Sombrero galaxy (inozivikanwa nehunyanzvi seMessier 104 kana M104 galaxy) inoratidzika seyakarongedzerwa pfumo, panzvimbo yeheti yeMexican yakapamhama Sombrero sezvayaionekwa muchiedza chaioneka. mifananidzo yakatorwa neSpitzer neHubble space telescopes.
Mufananidzo uchangoburwa weMessier 104 (M104) galaxy (inozivikanwa zvikuru seSombrero galaxy nekuda kwekufanana kwayo neheti yeMexican) yakatorwa neMid-Infrared Instrument (MIRI) yeJames Webb Space Telescope (JWST) yakapa ruzivo rutsva mu zvimiro zvemhete yayo yekunze nepakati.
Mumufananidzo mutsva we infrared, musimboti haupenye, Pane kudaro, tinoona dhisiki remukati rakatsetseka. Chimiro cheguruva pamwe chete nemhete yekunze yakagadziriswa zvakanyanya mumufananidzo mutsva uye masumbu akaoma anoonekwa kwekutanga. Izvi zvinosiyana nemifananidzo yakareruka inooneka yakatorwa kare neteresikopu yeSpitzer neHubble umo mukatikati unopenya wegwara renyeredzi unopenya uye mhete yekunze ichiita seyakatsetseka segumbeze.
Mumufananidzo mutsva wepakati-infrared renji, girazi rinoratidzika senge rakananga kupfura, pachinzvimbo cheyakafara-brimmed yeMexican hat Sombrero sezvaionekwa mumifananidzo yakare inooneka.
Vachishandisa data yeMIRI, vaongorori vakaona mapolycyclic anonhuwirira mahydrocarbon muhuruva anoungana pamwe nemhete yekunze yeSombrero galaxy. Kuvepo kwekabhoni (kureva, kukwirira kwesimbi) kunoratidza kuvepo kwenzvimbo dzenyeredzi dzechidiki mumhete yekunze, zvisinei izvi hazvitsigirwe nekuona. Gomba dema rakakura kwazvo riri pakati pegwara renzou iine kupenya kwakaderera kunoshanda galactic nucleus.
| Nyeredzi dzokutanga muchadenga dzine zero-simbi kana kuti yakaderera zvikuru-simbi. Vanodaidzwa kuti Pop III nyeredzi kana Population III nyeredzi. Nyeredzi dzesimbi dzakadzika iPop II nyeredzi. Nyeredzi diki dzine simbi dzepamusoro uye dzinonzi "Pop I stars" kana kuti solar metal stars. Iine simbi yakakwira 1.4%, zuva inyeredzi ichangoburwa. Mukuongorora nyeredzi, chero chinhu chinorema kupfuura helium chinoonekwa sesimbi. Makemikari asiri-simbi akaita seokisijeni, nitrogen nezvimwe simbi mune zve cosmological. Nyeredzi dzinowana simbi yakafumiswa muchizvarwa chega chega ichitevera chiitiko che supernova. Kuwedzera simbi yemukati munyeredzi kunoratidza zera rechidiki. |

Nzvimbo yekunze yegwara renzou inowanzogadzirwa nenyeredzi dzekare, dzisina simbi. Zvisineyi, kuyerwa kwesimbi kwaHubble (kureva kuwanda kwezvinhu zvinorema kupfuura helium munyeredzi) kwakaitwa kare kwakaratidza kuwanda kwenyeredzi dzine simbi muhombe yegwara renzou reSombrero zvichiratidza kuti zvizvarwa zvenyeredzi dzingangove dzakasangana nemhirizhonga yezviitiko zve supernovae mudunhu rekunze reSombrero. galaxy iyi. Kazhinji, halo yemapoka enyeredzi ine nyeredzi dzisina simbi, asi halo yeSombrero galaxy hairatidzi chero chiratidzo chenyeredzi dzinotarisirwa simbi-varombo. Zvinoshamisa kuti ine nyeredzi dzakapfuma nesimbi.
Gora renyeredzi reSombrero igwara renzou rinotenderera riri mamirioni makumi maviri nemasere chiedza-makore kubva paNyika muboka renyeredzi reMhandara. Isingaonekwe nemeso, yakawanikwa muna 28 neFrench nyanzvi yezvenyeredzi Pierre Méchain.
