Approach to the extremal limit of the Schwarzschild-de Sitter black hole
Alec Maassen van den Brink
The quasinormal-mode spectrum of the Schwarzschild-de Sitter black hole is studied in the limit of near-equal black-hole and cosmological radii. It is found that the mode_frequenci…

WKB analysis of the Regge-Wheeler equation down in the frequency plane
Alec Maassen van den Brink
The Regge-Wheeler equation for black-hole gravitational waves is analyzed for large negative imaginary frequencies, leading to a calculation of the cut strength for waves outgoing…

Unconventional Gravitational Excitation of a Schwarzschild Black Hole
P. T. Leung, Alec Maassen van den Brink, K. W. Mak +1
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…
