SGR 1935+2154 (or SGR J1935+2154) is a soft gamma repeater (SGR) that is an ancient stellar remnant, in the constellation Vulpecula, originally discovered in 2014 by the Neil Gehrels Swift Observatory

SGR J1550−5418 is a soft gamma repeater (SGR), the sixth to be discovered, located in the constellation Norma.Long known as an X-ray source, it was noticed to have become active on 23 October 2008, an

SGR 0525−66 (also known as PSR B0525−66) is a soft gamma repeater (SGR), located in the Super-Nova Remnant (SNR) 0525−66.1, otherwise known as N49, in the Large Magellanic Cloud. It was the first soft

SGR 0501+4516 is a soft gamma repeater (SGR), and is an ancient stellar remnant. Currently, the phenomenons of SGRs and the related Anomalous X-ray pulsars (AXP) are explained as arising from magnetar

SGR 1900+14 is a soft gamma repeater (SGR), located in the constellation of Aquila about 20,000 light-years away. It is assumed to be an example of an intensely magnetic star, known as a magnetar. It

A soft gamma repeater (SGR) is an astronomical object which emits large bursts of gamma-rays and X-rays at irregular intervals. It is conjectured that they are a type of magnetar or, alternatively, ne

SGR J1745−2900, or PSR J1745−2900, is the first-discovered magnetar orbiting the black hole Sagittarius A*, in the center of the Milky Way. The magnetar was discovered in 2013 using the Effelsberg 100
