What could those two things have in common?
Vela-X exploded some 11,000 years ago. How do we know that 11,000 years, was it carbon dated somehow? Because if so then the calibrated date to calendar years would have been 13,000 years. Could that have caused a significant increase in cosmogenic radioactivity that would have doubled the radio carbon production ( 14N + n -> 14C + 1H ) in the atmosphere at 13,000 years.
You can see that unexplainable radiocarbon spike (delta 14C detrented) here - third plot:
