“…Many other researchers have investigated the thermodynamic aspects of non-commutative black holes [18][19][20][21]. Yan [22,23] used the WKB method to calculate the QNMs of non-commutative black hole. Konoplya and Bronnikov et al [24,25] used WKB method to study Quasinormal ringing of regular black holes.…”

In this work, we investigate the scattering of massless plane scalar waves by the high dimensional non-commutative Schwarzschild–Tangherlini black hole. We use the partial wave approach to determine the scattering and absorption cross sections in the incident wavelength range. Our numerical results demonstrate that the bigger the non-commutative parameter, the smaller the maximum value of the related partial absorption cross section, however the tendency is slightly. We also discovered that when the non-commutative parameter is weak, the absorption cross section of the high dimensional black hole oscillates in the low frequency zone. The total absorption cross section oscillates around the geometrical optical limit in the high frequency range, and the scattering characteristics of black holes with various parameters are visibly different. The influence on the differential scattering cross section is particularly pronounced at large angles.
