Abstract: (arXiv)
Besides the well-known quasinormal modes, the gravitational spectrum of a Schwarzschild black hole also has a continuum part on the negative imaginary frequency axis. The latter is studied numerically for quadrupole waves. The results show unexpected striking behavior near the algebraically special frequency . This reveals a pair of unconventional damped modes very near , confirmed analytically.- black hole: Schwarzschild
- black hole: excited state
