Summary
| Description |
English: Gravitational lensing of an overextremal Kerr-Newman naked ring singularity with spin a/M=√2 and charge Q/M=√2, in natural units of G=K=c=1 (so a²+Q²=2M²). The observer is at r=50M and views the naked singularity from the equatorial plane (edge on); its left side is rotating towards the observer. FOV: 77.4°×38.7°. The equations that were used to raytrace the image can be found here. Comparison: Ref. 1[1] and Ref 2[2] |
