Shapes and Positions of Black Hole Shadows in Accretion Disks and Spin Parameters of Black Holes
Shapes and Positions of Black Hole Shadows in Accretion Disks and Spin Parameters of Black Holes
Can we determine the spin parameter of a black hole by observing the black hole's shadow on an accretion disk? To answer this question, we make qualitative and quantitative analyses of the shape and position of the shadow cast by a rotating black hole on an optically thick accretion disk …
