Reading between lines to model our galaxy's central black hole

Looks can be deceiving. The light from an incandescent bulb seems steady, but it actually flickers 120 times per second. Because the brain only perceives an average of the information it receives, this flickering is blurred and the perception of constant illumination is a mere illusion. While light cannot escape a black hole, the bright glow of rapidly orbiting gas (recall the 2019 images of M87’s black hole) has its own unique flicker. In a recent paper published in the Astrophysical Journal Letters on June 17, Lena Murchikova, William D.
