Tidal forces in dirty black hole spacetimes
Haroldo C. D. Lima Junior, Mateus M. Corrêa, Caio F. B. Macedo +1
Black holes can be inserted in very rich astrophysical environments, such as accretion disks. Although isolated black holes are simple objects in general relativity, their accretio…
Can different black holes cast the same shadow?
Haroldo C. D. Lima Junior, Luís C. B. Crispino, Pedro V. P. Cunha +1
We consider the following question: may two different black holes (BHs) cast exactly the same shadow? In spherical symmetry, we show the necessary and sufficient condition for a st…
Tidal forces in the charged Hayward black hole spacetime
Haroldo C. D. Lima Junior, Luís C. B. Crispino
Tidal forces produced by black holes are an important result of General Relativity, related to the spacetime curvature tensor. Among the astrophysical implications of tidal forces,…
On-Axis Tidal Forces in Kerr Spacetime
Haroldo C. D. Lima Junior, Luís C. B. Crispino, Atsushi Higuchi
Tidal forces are an important feature of General Relativity, which are related to the curvature tensor. We analyze the tidal tensor in Kerr spacetime, with emphasis on the case alo…
