Optical images of the Kerr–Sen black hole and thin accretion disk

Abstract This paper investigates the observable properties of a Kerr–Sen black hole surrounded by a thin accretion disk, focusing on the impact of the black hole’s spin and charge on the image. Using ray-tracing techniques, we conduct a detailed analysis of the black hole’s image, redshift distribut...
