2. Interested Topics New type of GW Source in massive gravity
(Recent progress is made mainly in this topic)
Quantum noise reduction in GW detectors

3. QNMs of a new black hole solution in massive gravity

4. 1. A new black hole solution in massive gravity
We obtain a new black hole solution in massive gravity as follows

5. 2. QNMs of this new black hole
Now, we consider concretely the behaviors of the space-time
under scalar perturbation. The Regge-Wheeler equation is

6. We list the results of QNMs in the following tables

7. Obviously, this kind of black hole is stable against external perturbation.
