Cloud 9, yaln\u0131zca s\u0131ra d\u0131\u015f\u0131 yap\u0131s\u0131yla de\u011fil, evrenin erken d\u00f6nemlerinde galaksilerin nas\u0131l olu\u015ftu\u011funa dair kritik ipu\u00e7lar\u0131 bar\u0131nd\u0131rmas\u0131yla da dikkat \u00e7ekiyor.

Y\u0131ld\u0131z\u0131 olmayan, ba\u015far\u0131s\u0131z bir galaksi<\/b><\/p>\n

Avrupa Uzay Ajans\u0131 (ESA) ad\u0131na \u00e7al\u0131\u015fan AURA\/STScI\u2019dan Andrew Fox, Cloud 9\u2019un \u00f6nemini \u201cBu bulut, karanl\u0131k evrene a\u00e7\u0131lan bir pencere\u201d<\/em> s\u00f6zleriyle \u00f6zetliyor. Bilim camias\u0131na g\u00f6re evrendeki toplam maddenin yakla\u015f\u0131k %85\u2019i karanl\u0131k maddeden<\/strong> olu\u015fuyor. Ancak karanl\u0131k madde \u0131\u015f\u0131kla etkile\u015fime girmedi\u011fi i\u00e7in do\u011frudan g\u00f6zlemlenemiyor ve varl\u0131\u011f\u0131 yaln\u0131zca k\u00fctle\u00e7ekim etkileri \u00fczerinden anla\u015f\u0131labiliyor.<\/p>\n

Cloud 9, bu a\u00e7\u0131dan benzersiz bir \u00f6rnek<\/strong> sunuyor. \u00c7\u00fcnk\u00fc yap\u0131, karanl\u0131k maddenin bask\u0131n oldu\u011fu bir bulut olmas\u0131na ra\u011fmen i\u00e7inde hi\u00e7 y\u0131ld\u0131z bar\u0131nd\u0131rm\u0131yor. Bu durum, teorik olarak uzun s\u00fcredir \u00f6ng\u00f6r\u00fclen ancak \u015fimdiye kadar do\u011frudan do\u011frulanamayan bir kozmik senaryoyu destekliyor.<\/p>\n

<\/span> Bilimsel olarak RELHIC<\/strong> (Reionization-Limited Hydrogen I Cloud) olarak s\u0131n\u0131fland\u0131r\u0131lan Cloud 9\u2019un i\u00e7inde hidrojen gaz\u0131 bulunuyor. Normal \u015fartlarda bu t\u00fcr yo\u011fun gaz bulutlar\u0131nda y\u0131ld\u0131z olu\u015fumunun ba\u015flamas\u0131 bekleniyor. Ancak Cloud 9\u2019da bu s\u00fcre\u00e7 hi\u00e7 ger\u00e7ekle\u015fmemi\u015f. Ara\u015ft\u0131rmac\u0131lar, bunun temel nedeninin y\u0131ld\u0131z olu\u015fumunu tetikleyecek kadar gaz birikmemesi oldu\u011funu d\u00fc\u015f\u00fcn\u00fcyor. <\/figure>\n

\u00c7al\u0131\u015fman\u0131n lideri Alejandro Benitez-Llambay, bu durumu \u201cBu, ba\u015far\u0131s\u0131z bir galaksinin hikayesi\u201d <\/em>s\u00f6zleriyle tan\u0131ml\u0131yor. Benitez-Llambay\u2019a g\u00f6re y\u0131ld\u0131zlar\u0131n yoklu\u011fu, teorinin do\u011frulu\u011funu kan\u0131tlayan en g\u00fc\u00e7l\u00fc unsur. \u00c7\u00fcnk\u00fc Cloud 9, yerel evrende g\u00fcn\u00fcm\u00fcze kadar bozulmadan kalm\u0131\u015f ilkel bir galaksi yap\u0131 ta\u015f\u0131 niteli\u011fi ta\u015f\u0131yor.<\/p>\n

Bilim insanlar\u0131, RELHIC\u2019lerin varl\u0131\u011f\u0131n\u0131 uzun s\u00fcredir teorik olarak \u00f6ng\u00f6r\u00fcyordu. Ancak Hubble\u2019\u0131n y\u00fcksek hassasiyeti olmasayd\u0131 Cloud 9\u2019un ke\u015ffi m\u00fcmk\u00fcn olmayabilirdi. Bu ke\u015fif, evrende Cloud 9 benzeri ba\u015fka \u201cdonmu\u015f\u201d ya da geli\u015fimini tamamlayamam\u0131\u015f galaksilerin de bulunabilece\u011fine i\u015faret ediyor.<\/p>\n

K\u00fc\u00e7\u00fck ama son derece yo\u011fun bir yap\u0131<\/b><\/p>\n

Cloud 9, Samanyolu \u00e7evresinde bilinen hidrojen bulutlar\u0131yla kar\u0131\u015ft\u0131r\u0131lmamas\u0131 gereken \u00f6zelliklere sahip. Yap\u0131, daha k\u00fc\u00e7\u00fck, daha kompakt ve neredeyse kusursuz derecede k\u00fcresel bir form sergiliyor. \u00c7ekirde\u011fi n\u00f6tr hidrojenden olu\u015fan bulutun \u00e7ap\u0131 yakla\u015f\u0131k 4.900 \u0131\u015f\u0131k y\u0131l\u0131<\/strong>. Hidrojen gaz\u0131n\u0131n toplam k\u00fctlesi G\u00fcne\u015f\u2019in yakla\u015f\u0131k 1 milyon kat\u0131 olarak hesaplan\u0131rken karanl\u0131k madde k\u00fctlesinin ise 5 milyar G\u00fcne\u015f k\u00fctlesine ula\u015ft\u0131\u011f\u0131 tahmin ediliyor.<\/p>\n

Ara\u015ft\u0131rma ekibine g\u00f6re Cloud 9, gelecekte yeterli miktarda -yakla\u015f\u0131k 5 milyar G\u00fcne\u015f k\u00fctlesi- hidrojen gaz\u0131 toplayabilirse y\u0131ld\u0131zlarla dolu bir galaksiye d\u00f6n\u00fc\u015fme potansiyeline sahip<\/strong>. Astronomlar, bundan sonraki s\u00fcre\u00e7te Cloud 9 benzeri RELHIC\u2019leri bulmay\u0131 umuyor.<\/p>\n\n
