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…
Observational Signature of High Spin at the Event Horizon Telescope
Samuel E. Gralla, Alexandru Lupsasca, Andrew Strominger
We analytically compute the observational appearance of an isotropically emitting point source on a circular, equatorial orbit near the horizon of a rapidly spinning black hole. Th…
Inclined Pulsar Magnetospheres in General Relativity: Polar Caps for the Dipole, Quadrudipole and Beyond
Samuel E. Gralla, Alexandru Lupsasca, Alexander Philippov
In the canonical model of a pulsar, rotational energy is transmitted through the surrounding plasma via two electrical circuits, each connecting to the star over a small region kno…
