Kerr-Newman black holes with scalar hair

Jorge F. M. Delgado, Carlos A. R. Herdeiro, Eugen Radu +1

We construct electrically charged Kerr black holes (BHs) with scalar hair. Firstly, we take an uncharged scalar field, interacting with the electromagnetic field only indirectly, v…

Chaotic lensing around boson stars and Kerr black holes with scalar hair

P. V. P. Cunha, J. Grover, C. Herdeiro +3

In a recent letter, arXiv:1509.00021, it was shown that the lensing of light around rotating boson stars and Kerr black holes with scalar hair can exhibit chaotic patterns. Since n…

Non-linear Q-clouds around Kerr black holes

Carlos Herdeiro, Eugen Radu, Helgi Runarsson

Q-balls are regular extended `objects' that exist for some non-gravitating, self-interacting, scalar field theories with a global, continuous, internal symmetry, on Minkowski space…
