Аннотация: Проанализированы свойства рентгеновского излучения активного ядра галактики NGC 7172 типа Сейферт 2 по данным наблюдений космической обсерватории NuSTAR в 2014 г. Источник демонстрирует постоянное во времени поглощение NH ≈ 8-1022 cм-2, значение которого сравнимо с полученным поглощением из наблюдений XMM-Newton, «Suzaku», ASCA и BeppoSAX за предыдущие три десятилетия. Базовый спектральный анализ выявил наличие умеренной составляющей отражения с |
