Black hole images under spherical-shell and circular-annulus accretion models in Schwarzschild spacetime: a semianalytical approach
Abstract In the static and infalling spherical-shell models of optically thin accretion on Schwarzschild black hole, the formulas for the integrated intensities observed by a distant observer are derived, and by taking the monochromatic emission pattern with a $$1/r^{2}$$ 1 / r 2 radial profile as e...
