From: Quasinormal modes and shadow of noncommutative black hole
Complex plane of the QNMs. In plot (a) we have the results obtained by the WKB approximation, while in (b) we use continuous fraction. The markers denote the multipole number as: \(l=1\) (circle), \(l=2\) (square) and \(l=3\) (diamond), while the colors denote the value of the noncommutative parameter \(\Theta =0\) (black), \(\Theta =0.05\) (red), \(\Theta =0.10\) (blue) and \(\Theta =0.12\) (green).
