Спутник ФКИ. Fermi Gamma-ray Space Telescope. [Редактировать]

GLAST (Gamma-ray Large Area Space Telescope), впоследствии названный Fermi Gamma-ray Space Telescope, — космическая обсерватория для изучения, с низкой земной орбиты, больших областей космоса в диапазоне гамма-излучения. С его помощью астрономы намерены исследовать астрофизические и космологические процессы, происходящие в активных ядрах галактик, пульсарах и других высокоэнергетических источниках; также будут изучаться гамма-всплески, вестись поиски тёмной материи.

Научные приборы

  • LAT — гамма-телескоп предназначен для наблюдений в диапазоне энергий от нескольких десятков МэВ до сотен ГэВ. Чувствительность на энергии 100 МэВ в 50 раз выше, чем у его предшественника EGRET Комптоновской обсерватории. При этом LAT будет получать гораздо более чёткие изображения и лучше определять координаты источников.
  • Fermi GBM — прибор для регистрации гамма-всплесков. Ожидается, что он будет регистрировать около 200 событий в год. Это немного, но задача простого увеличения числа известных всплесков перед ним и не ставится. Интереснее детально разобраться с тем, как гамма-всплески светят в жёстком гамма-диапазоне, на энергиях порядка ГэВ. Комптоновская обсерватория увидела несколько очень жёстких всплесков, но вопросов осталось больше, чем ответов.
