Emergent flux from particle collisions near a Kerr black hole

“…It is very easy to check using our results above that the change from Schwarzschild to Kerr makes very little difference to the escape function. Moreover, some work we have done, and upcoming work [16], shows that going to three-dimensions does not change the results significantly, thus corroborating our intuition. The concern about the DM density profile is rather more serious, because the density enters the flux quadratically.…”

“…To do this for general a analytically is tricky, and we choose to investigate two values of a, namely a = 0, the Schwarzschild limit, and the extreme Kerr case of a = 1. Other values of a give results that are numerically not too different from the analytic results presented below and we leave the details of a numerical treatment for arbitrary a to future work [16]. Our goal here is to find an estimate for the emergent flux rather than to give a precise prediction.…”

“…For simplicity we restrict our analysis to the equatorial plane. In a paper to appear, a numerical analysis is performed, [16], where it is shown that this approximation is indeed a good one to the accuracy to which we wish to work in this analysis.…”
