Спутник ФКИ. WMAP. [Редактировать]

WMAP (Wilkinson Microwave Anisotropy Probe) — космический аппарат НАСА, предназначенный для изучения реликтового излучения, образовавшегося в результате Большого взрыва. Запущен 30 июня 2001 года. С октября 2001 по 2009 год передавал на Землю результаты сканирования небесной сферы; на основе данных была составлена радиокарта неба на нескольких длинах волн: от 1,4 см до 3 мм. В настоящий момент выведен из эксплуатации. Изначально аппарат назывался MAP (англ. «карта»). После кончины одного из научных руководителей проекта, Дэвида Уилкинсона (Wilkinson) 5 сентября 2002 года, спутник был переименован в его честь.
Собранная WMAP информация позволила учёным построить самую детальную на сегодняшний день карту флуктуаций температуры распределения микроволнового излучения на небесной сфере (если исключить данные полученные с Planck). Ранее подобную карту удалось построить по данным аппарата НАСА COBE, однако её разрешение существенно — в 35 раз — уступало данным, полученным WMAP. Данные WMAP показали, что распределение температуры реликтового излучения по небесной сфере соответствует полностью случайным флуктуациям с нормальным распределением. Параметры функции, описывающей измеренное распределение, согласуются с моделью Вселенной, состоящей: на 4 % из обычного вещества, на 23 % из так называемой тёмной материи (возможно, из гипотетических тяжёлых суперсимметричных частиц) и на 73 % из ещё более таинственной тёмной энергии, вызывающей ускоренное расширение Вселенной.
Данные WMAP позволяют утверждать, что тёмная материя является холодной (то есть состоит из тяжёлых частиц, а не из нейтрино или каких-либо других лёгких частиц). В противном случае лёгкие частицы, движущиеся с релятивистскими скоростями, размывали бы малые флуктуации плотности в ранней Вселенной. Среди других параметров, из данных WMAP определены (исходя из ΛCDM-модели, то есть фридмановской космологической модели с Λ-членом и холодной тёмной материей англ. Cold Dark Matter):

  • возраст Вселенной: (13.73 ± 0.12)·109 лет;
  • постоянная Хаббла: 71 ± 4 км/с/Мпк;
  • плотность барионов в настоящее время: (2,5 ± 0,1)·10−7 см−3;
  • параметр плоскостности Вселенной (отношение общей плотности к критической): 1,02 ± 0,02;
  • суммарная масса всех трёх типов нейтрино: <0,7 эВ.
