Gde nahoditsya temnaya materiya? Vrashenie galaktik i ih dvizhenie v skopleniyah proishodit tak, kak budto tam sushestvuet ogromnoe kolichestvo nevidimogo veshestva. No prisutstvuet li eta temnaya materiya takzhe i vo vsem prostranstve Vselennoi? Otvet mozhno poluchit', sravnivaya raspredelenie nablyudaemyh galaktik, s rezul'tatami chislennogo modelirovaniya. Tochnost' etogo sravneniya nedavno udalos' znachitel'no povysit' blagodarya tomu, chto stali dostupny rezul'taty nablyudeniya bolee chem 100 000 galaktik, vypolnennye v ramkah Obzora krasnyh smeshenii galaktik na instrumente 2dF (2-Degree Field Galactic Redshift Survey). Na privedennom kadre komp'yuternoi modeli pokazano sechenie nashei Vselennoi razmerom 300 millionov svetovyh let. Temnaya materiya predstavlena serym, a galaktiki cvetnymi kruzhkami. Krasnyi pryamougol'nik ukazyvaet mestopolozhenie bogatogo skopleniya galaktik, a zelenyi bolee tipichnoe dlya nashei Vselennoi mesto. Issledovaniya ukazyvayut, chto moshnaya gravitaciya temnoi materii prityagivaet k nei obychnoe veshestvo, tak, chto svetyashayasya i temnaya materiya fakticheski styagivayutsya v odni i te zhe oblasti prostranstva. |
