QNM

A Mathematica package for computing quasinormal mode solutions of the Teukolsky equation in Schwarzschild and Kerr spacetime. The package introduces two new functions:

QNMFrequency[s, l, m, n, a]
QNMRadial[s, l, m, n, a]

where
$s$ - is the spin-weight of the field
$l$ - is the multipolar index
$m$ - is the azimuthal index
$n$ - is the overtone number
$a$ - is the black hole spin parameter

Further examples

Additional documentation can be found in the Mathematica documentation included with the package.

Citing

In addition to acknowledging the Black Hole Perturbation Toolkit as suggested on the front page we also recommend citing the specific package version you use via the citation information on the package’s Zenodo page linked from the above DOI.
