'''N49'''或'''LMC N49'''<ref name=NED/>'''PKS 0525-66'''、<ref name=SIMBAD/><ref name=NED/>PKS B0525-661、<ref name=NED/>PKS J0525-6604、<ref name=NED/>'''SNR J052559-660453'''<ref name=SIMBAD/>，是[[大麥哲倫星系]]中最明亮的[[超新星遗迹]]，距離地球約16萬光年，約5000年前形成<ref name=Chandra />。

== 概要 ==
[[钱德拉X射线天文台]]最新拍攝的N49影像顯示有一個子彈型狀的物體以每小時五百萬英里的速度從一個明亮的X射線和[[伽马射线]]點源射出。這可能是一顆擁有極強磁場的[[中子星]]，被稱為{{link-en|軟伽瑪射線復發源|Soft gamma repeater}}<ref name=Chandra />。1979年3月5日在N49內發現極強烈的伽瑪射線爆發<ref name=Anne />。
