12 milyar \u0131\u015f\u0131k y\u0131l\u0131 uzakl\u0131kta bulunan g\u00f6kadalar\u0131 \u00e7evreleyen ve hafif par\u0131lt\u0131lar i\u00e7eren gaz toplamlar\u0131n\u0131 inceleyen astronomlar, bu yap\u0131lar yoluyla “kozmik a\u011f” olarak bilinen bir yap\u0131n\u0131n varl\u0131\u011f\u0131n\u0131 kan\u0131tlad\u0131.

Teoriye g\u00f6re bu dev filamentlerin kesi\u015fti\u011fi yerler galaksilerin olu\u015ftu\u011fu yerlerdir. Arizona \u00dcniversitesi’nde \u00e7al\u0131\u015fma y\u00fcr\u00fcten astrofizik\u00e7i Erika Hamden’in ara\u015ft\u0131rmalar\u0131, bu t\u00fcrden filamentlerin var olabilece\u011fine dair ipu\u00e7lar\u0131 ta\u015f\u0131maktayd\u0131. Hamden daha \u00f6nce uzak galaksilere ili\u015fkin spektrum \u00e7al\u0131\u015fmalar\u0131nda, hedef noktas\u0131na gelen \u0131\u015f\u0131\u011f\u0131n yolda b\u00fcy\u00fck hidrojen bulutlar\u0131ndan ge\u00e7ti\u011fini g\u00f6steren \u00e7al\u0131\u015fmalar da yapm\u0131\u015ft\u0131. Erika Hamden, “Yani galaksilerle aram\u0131zda bir s\u00fcr\u00fc oksijen molek\u00fcl\u00fc oldu\u011fu s\u00f6ylenebilir” diyor.<\/p>\n
Ancak bu durum ger\u00e7ekle\u015firken \u0131\u015f\u0131\u011f\u0131n, kozmik a\u011f\u0131n fragmentlerinden birinden mi yoksa daha fazlas\u0131ndan m\u0131 ge\u00e7ti\u011fi bilinmemektedir. Bununla birlikte, Science dergisinde yay\u0131nlanan bir makalede Japonya’da bir astronom olarak \u00e7al\u0131\u015fma y\u00fcr\u00fcten Hideki Umehata liderli\u011findeki bir ekip, Kova tak\u0131my\u0131ld\u0131z\u0131na do\u011fru 12 milyar \u0131\u015f\u0131k y\u0131l\u0131 yay\u0131l\u0131ma sahip olan ve SSA22 olarak kodlanm\u0131\u015f olan protogalaksiye bakmak i\u00e7in d\u00fcnyan\u0131n en b\u00fcy\u00fck teleskoplar\u0131ndan birini kulland\u0131. I\u015f\u0131\u011f\u0131n kat etti\u011fi mesafenin izlenmesi yoluyla, uzakta bulunan galaksilerin ke\u015ffi sa\u011flanabilir.<\/p>\n
Umehata \u00f6nc\u00fcl\u00fc\u011f\u00fcndeki ekip, yak\u0131n galaksilerden gelen y\u00fcksek enerjili radyasyonla hidrojen \u0131\u015f\u0131mas\u0131n\u0131 ara\u015ft\u0131rmak i\u00e7in \u0131\u015f\u0131\u011f\u0131 bir spektroskoptan ge\u00e7irdi. Umehata’n\u0131n ara\u015ft\u0131rmas\u0131na ili\u015fkin a\u00e7\u0131klamalarda bulunan Hamden “Bu galaksiler, el feneri gibi davran\u0131yor” diyor. Ayr\u0131ca \u00e7al\u0131\u015fmaya bu yap\u0131lar\u0131n tespitini m\u00fcmk\u00fcn k\u0131lan MUSE ad\u0131 verilen spektrografik ara\u00e7 eklendi. Bu ara\u00e7, hidrojen gibi maddelerin spektroskopik imzalar\u0131n\u0131n aramas\u0131n\u0131 sa\u011flayan y\u00fcksek \u00e7\u00f6z\u00fcn\u00fcrl\u00fckl\u00fc bir spektrograf. Hamden bu noktaya dair a\u00e7\u0131klamalarda bulunarak “Bu \u00e7al\u0131\u015fman\u0131n sonu\u00e7 vermesinin tek nedeni bu. \u00c7\u00fcnk\u00fc bu yap\u0131lar o kadar b\u00fcy\u00fckt\u00fcr ki, onlar\u0131 g\u00f6rmek i\u00e7in b\u00fcy\u00fck bir g\u00f6r\u00fc\u015f alan\u0131na ihtiyac\u0131n\u0131z var” dedi ve ekledi: “Bu \u00f6nemli bir sonu\u00e7 \u00e7\u00fcnk\u00fc kozmik a\u011f, standart kozmoloji modelinin temel \u00f6ng\u00f6r\u00fclerinden biri. Bu yap\u0131ya dair bir par\u00e7a bulmak, do\u011fru yolda oldu\u011fumuzun bir g\u00f6stergesidir.”<\/p>\n
