Critical Emission from a High-Spin Black Hole
Alexandru Lupsasca, Achilleas P. Porfyriadis, Yichen Shi
We consider a rapidly spinning black hole surrounded by an equatorial, geometrically thin, slowly accreting disk that is stationary and axisymmetric. We analytically compute the br…

Photon Emission Near Extreme Kerr Black Holes
Achilleas P. Porfyriadis, Yichen Shi, Andrew Strominger
Ongoing astronomical efforts extract physical properties of black holes from electromagnetic emissions in their near-vicinity. This requires finding the null geodesics which extend…
