Formation of Black Holes Imbedded in Galaxies: Neutrino Emission before the Event Horizon; Condensate vs Event Horizon BHs
The Brightest Matter, the Brightest Energy, the brightest quasi-star of the Universe (by very many orders of magnitude) is associated with the formation of the majority of the thin, flat rotation curve, spiral galaxies, each with a Super Massive Black Hole near their exact (dr/r ~ 3 x 10^-4) center and thus young, before mergers. Since this is occurring in some cases before Z>6, a time much less time than the Eddington limit time, we postulate a black collapse for half the mass where matter accretes to the black hole without the emission of Plank radiation. Accretion occurs from a giant gaseous polytrope formed by self-gravity instabilities transporting angular momentum in the proto-galactic flat rotation curve mass distribution. Polytropic evolution predicts the emission of the heat and chemical potential of the accreting matter by pair neutrino emission for some mass fraction, ~ 10^-3, before crossing the event horizon, thus accreting de-leptonized matter. If the black hole is a condensate star, a gravistar, a pressure boundary condition should enhance the neutrino emission above that from a classical event horizon. The neutrino signal may be detectable by Gadzooks. (Supported by the DOE)
