However it seems a regular flaring star, orbiting the supermassive central galaxy black hole, flaring each 114 days by DITCHING at some repelling black hole horizon.
Conclusion: a supermassive black hole gives off bursts of energy every 114 days as it tears off chunks of an orbiting star.
Which is a support for the (new physic) fermion repelling black hole horizon of tne new Q-FFF Theory.
Even S.Hawking did suggest and recently R Penrose suggested a new black hole horizon. see:
