Hairy rotating black holes in cubic Galileon theory

Understand

Numerical solutions for asymptotically flat rotating black holes in the cubic Galileon theory are presented.

• These black holes are endowed with a nontrivial scalar field and exhibit a non-Schwarzschild behaviour: faster than $1/r$ convergence to Minkowski spacetime at spatial infinity and hence vanishing of the Komar mass.
• The metrics are compared with the Kerr metric for various couplings and angular velocities.
• Their physical properties are extracted and show significant deviations from the Kerr case.
