What astronomical object emerges sometimes from supernova instead of a black hole?

Magnetar
Blazar
Quasar
only a black hole can emerge from supernova
A magnetar is a type of neutron star with an ex­treme­ly powerful magnetic field. The magnetic field decay powers the emission of high­-en­er­gy elec­tro­mag­net­ic ra­di­a­tion, par­tic­u­lar­ly X-rays and gamma rays. As of March 2016, only 23 mag­ne­tars are known, with six more can­di­dates awaiting con­fir­ma­tion.
