Black hole images under spherical-shell and circular-annulus accretion models in Schwarzschild spacetime: a semianalytical approach
Bofeng Wu, En-Wei Liang, Xiao Zhang
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 observ…
