what is SDSS J113323.97+550415.8
1 a blazar nuclei of a star system
2 an ejected neutron star that pulled nearby super luminous variable stars out of markarian 177 into an orbit around makarian 177
3 a millisecond magnetar (magnetar+pulsar) that was pulled out of nearby makarian 178 into orbit around markarian 177 sending a continuous burst of gamma rays
4 a supermassive black hole from a galaxy consumed by a younger markarian 177 sending the supermassive black hole out after failing to be consumed eventually sent out flying with its surrounding stars it put into a tight orbit around into a stable orbit around markarian 177 and forming a HCSS.
5 an intermediate mass quasar sent into an orbit around markarian 177 dragging along several pulsars and neutron stars and causing heavy tidal forces on them causing massive GRB's, ARB's, BRB's, and ERB's to be sent out.
