Analytical computation of quasi-normal modes of slowly-rotating black-holes in dCS gravity

Understand

Using gravitational wave observations to search for deviations from general relativity in the strong-gravity regime has become an important research direction.

• Chern Simons (CS) gravity is one of the most frequently studied parity-violating models of strong gravity.
• It is known that the Kerr black-hole is not a solution for CS gravity.
• At the same time, the only rotating solution available in the literature for dynamical CS (dCS) gravity is the slow-rotating case most accurately known to quadratic order in spin.
