    • they said that it shows the emission of electromagnetic energy has the same cause, but didn’t explain what that cause is…

    • they said that magnetars don’t emit energy all the time, so we had to catch them when they did emit: that is false: we have to catch them when they’re emitting at us, which is a very-different frame-of-reference.

    Also, if the things are neutron-stars, then how the hell can they even have any electromagnetic field?

    Neutrons are neutral.

    It must be a crust of non-neutron protons & electrons, or the plasma swirling in, or something, that’s producing the electromagnetic field…

    No need to bother commenting on anything I say:

    just random thoughs flitting through a deteriorating old brain…

      Your last one is a good question. I don’t have an answer but I was leaning towards some sort of conservation law (e.g. normal stars have magnetic fields, when they get squeezed down to a neutron star those fields must go somewhere and it will be very much “concentrated”). Apparently this is a bit too easy (didn’t expect to be nothing different). Wikipedia provides a reference to a not too recent (2003) survey, namely this one: https://arxiv.org/abs/astro-ph/0307133 . I don’t know if it’s the state of the art but it surely is interesting.
