GW150914 and GW150914-GBM revisited

[QUOTE="Chronos, post: 5487955, member: 10970"] The association between the LIGO detection of a black hole merger event and Fwemi detection of a short GRB appears to be unsettled based on this paper [URL]http://arxiv.org/abs/1602.07352[/URL], Fermi GBM signal contemporaneous with GW150914 - an unlikely association. The author points out the magnetic field strength required and unlikelihood of sufficient plasma in a binary black hole system to account for an EM signal of the power measured. While statistics claiming an association between the GRB and GW signal are impressive, the lack of a credible astrophysical mechanism to account for the GRB signal is not. The non-detection by other capable instruments [e.g., Swift, INTEGRAL, IceCube & ANTARES] is also unassuring. [/QUOTE]
