A second coherent radio burst spanning 704-4032 MHz with spectral index -2.18, 54% linear and 22% circular polarization, and an orthogonal polarization angle jump was detected from 2XMM J104608.7-594306, showing rare radio activity in sources thought to be radio-quiet.
A Monte Carlo model of a Kerr black hole corona shows that photon collisions create a dense electron-positron pair cloud concentrated near the black hole, yielding X-ray temperatures, Compton parameters, and 4-10% polarization consistent with binary black hole observations.
Case study of four GRBs finds afterglow light curves shaped by ambient density, not prompt fireball composition, with cascade pairs affecting only long GRB early optical emission.

Pair-Rich Corona of an Accreting Kerr Black Hole
