Pair-Rich Corona of an Accreting Kerr Black Hole
Jonathan Zhang, Christopher Thompson
We build a self-consistent model of a warm scattering corona near an accreting black hole in Kerr geometry, in the regime of slow ( Eddington) mass accretion. An iterati…

Searching for Axion Dark Matter Near Relaxing Magnetars
Sandip Roy, Anirudh Prabhu, Christopher Thompson +3
Axion dark matter passing through the magnetospheres of magnetars can undergo hyper-efficient resonant mixing with low-energy photons, leading to the production of narrow spectral…

Quantum Plasma Creation near a Magnetar
Jonathan Zhang, Christopher Thompson
Magnetars in quiescent states continue to emit hard X-rays with a power far exceeding the loss of rotational energy. It has recently been noted that this hard X-ray continuum may b…
