The nature of Coma's X-rayemission is still being investigated.
后发星系团X射线发射的性质仍在查证中。

The scientists found the observed X-rayemission was a factor of 30 to 50 times smaller than expected from the accretion scenario, effectively ruling it out.
科学家发现，观测到的X射线辐射要比吸积模型预言的少上30到50倍，这有效地将该模型排除了。

A supernova from a merger of two white dwarfs, on the other hand, would create significantly less X-rayemission than the accretion scenario.
