A The brightest, furthest pulsar in the universe

    An interesting challenge for the theorists:
    An Ultra-Luminous X-ray source (ULX) has been found (NGC 5907 X-1) which definitely seems to contain a pulsar, yet it appears to be far more powerful than other such sources which have been assumed to be powered by black holes.

    The emission appears to be far greater than the Eddington limit (where radiation pressure would prevent further infalling material) but the discovery team are suggesting that complex magnetic fields near to the surface could somehow get round that (perhaps by sweeping material in against the radiation pressure).

    Thanks for the thread! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post? The more details the better.
