Quasinormal modes and topological characteristics of a Schwarzschild black hole surrounded by the Dehnen type dark matter halo
Abstract In this study, we investigate a Schwarzschild black hole surrounded by Dehnen-type dark matter. A comprehensive thermodynamic analysis of black holes is conducted, leading to the calculation of black hole remnants. We investigate the trajectory of light, establishing an upper limit for the...

| description | Abstract In this study, we investigate a Schwarzschild black hole surrounded by Dehnen-type dark matter. A comprehensive thermodynamic analysis of black holes is conducted, leading to the calculation of black hole remnants. We investigate the trajectory of light, establishing an upper limit for the parameters based on Event Horizon Telescope (EHT) observations of Sgr A*, ensuring that the black hole’s shadow resides within the allowed region. Furthermore, we derive the quasinormal modes (QNMs) for both scalar and electromagnetic perturbations. Utilizing a topological framework, we examine the stability of the photon sphere and classify the topology of the black hole in accordance with its thermodynamic potentials. |
