PSR B0525-66
PSR B0525-66 is a soft gamma repeater located in the Large Magellanic Cloud. This was the first soft gamma repeater discovered, and as of 2015, the only known located outside our galaxy. It was discovered in 1979 and located by using the measurement of the arrival time differences of the signal by the set of artificial satellites equipped with detectors gamma rays. The origin of the signal from the pulsar is from a supernova remnant called N49 which it has long been associated, although the association can only be indirect: it seems clear that soft gamma repeaters form in young stellar clusters, it is not certain that the explosion that gave birth to SGR 0525-66 is also the one that produced the remnant N49.
