It does?

I am not aware of any papers which explain the Subaru observations of the Coma cluster in terms of "electricity and magnetism".

Would you be kind enough to provide a reference please?

Alternatively, if you are talking in general terms, would you be kind enough to provide some references (to papers published in relevant peer-reviewed journals) that model inter-galactic environments and include "electricity and magnetism"?

Oh, and would you at least acknowledge the question I asked you in an earlier post? And if you intend to have a go at answering it, please say so?
