Lensing and shadow of a black hole surrounded by a heavy accretion disk
Pedro V. P. Cunha, Nelson A. Eiró, Carlos A. R. Herdeiro +1
We consider a static, axially symmetric spacetime describing the superposition of a Schwarzschild black hole (BH) with a thin and heavy accretion disk. The BH-disk configuration is…
EHT constraint on the ultralight scalar hair of the M87 supermassive black hole
Pedro V. P. Cunha, Carlos A. R. Herdeiro, Eugen Radu
Hypothetical ultralight bosonic fields will spontaneously form macroscopic bosonic halos around Kerr black holes, via superradiance, transferring part of the mass and angular momen…
Spontaneously scalarised Kerr black holes
Pedro V. P. Cunha, Carlos A. R. Herdeiro, Eugen Radu
We construct asymptotically flat, spinning, regular on and outside an event horizon, scalarised black holes (SBHs) in extended scalar-tensor-Gauss-Bonnet models. They reduce to Ker…
