Black.Hole,Extremal.Kerr.Newman,Raytracing.png(800 × 430 pixels, file size: 262 KB, MIME type: image/png)


English: Extremal Kerr-Newman black hole with spin a/M=√½ and charge Q/M=√½, in natural units of G=K=c=1. Therefore a²+Q²=M². The observer is at r=50M and views the black hole from the equatorial plane (edge on). FOV: 77.4°×38.7°. The equations that were used to raytrace the image can be found here.
