Spinning black holes with a separable Hamilton-Jacobi equation from a modified Newman-Janis algorithm
Haroldo C. D. Lima Junior, Luís C. B. Crispino, Pedro V. P. Cunha +1
Obtaining solutions of the Einstein field equations describing spinning compact bodies is typically challenging. The Newman-Janis algorithm provides a procedure to obtain rotating…
Stationary black holes and light rings
Pedro V. P. Cunha, Carlos A. R. Herdeiro
The ringdown and shadow of the astrophysically significant Kerr Black Hole (BH) are both intimately connected to a special set of bound null orbits known as Light Rings (LRs). Does…
Shadows of charged rotating black holes: Kerr-Newman versus Kerr-Sen
Sérgio Vinicius M. C. B. Xavier, Pedro V. P. Cunha, Luís C. B. Crispino +1
Celebrating the centennial of its first experimental test, the theory of General Relativity (GR) has successfully and consistently passed all subsequent tests with flying colours.…
