Soft gamma repeaters (SGRs) are a class of astronomical objects that emit bursts of gamma rays and are thought to be highly magnetized neutron stars, also known as magnetars. These bursts of gamma rays are typically soft, meaning they have lower energy compared to other gamma-ray bursts. SGRs are characterized by their intermittent bursts of gamma radiation and X-rays, which can last from a few milliseconds to several minutes, and occur sporadically.
