Previous observations of superluminous supernovae found they typically reside in low - mass or dwarf galaxies, which tend to be less enriched in metals than more massive galaxies. (sciencedaily.com)
The supernova known as DES15E2mlf is unusual even among the small number of superluminous supernovae astronomers have detected so far. (sciencedaily.com)
While the brightness of SN 2017egm and the properties of the magnetar that powers it overlap with those of other superluminous supernovas, the amount of mass ejected by SN 2017egm may be lower than the average event. (sciencedaily.com)
