Quasi-normal modes, emission rate, and shadow of charged AdS black holes with perfect fluid dark matter

Original language description

In this study, we comprehensively investigated charged AdS black holes surrounded by a distinct form ofdark matter. In particular, we focused on key elements including the Hawking temperature, quasi-normal modes(QNMs), emission rate, and shadow. We first calculated the Hawking temperature, thereby identifying critical valuessuch as the critical radius and maximum temperature of the black hole, essential for determining its phase transition.Further analysis focused on the QNMs of charged AdS black holes immersed in perfect fluid dark matter (PFDM)within the massless scalar field paradigm. Employing the Wentzel-Kramers-Brillouin (WKB) method, we accuratelyderived the frequencies of these QNMs. Additionally, we conducted a meticulous assessment of how the intensityof the PFDM parameter α influences the partial absorption cross sections of the black hole, along with a detailedstudy of the frequency variation of the energy emission rate. The pivotal role of geodesics in understanding astrophysicalblack hole characteristics is highlighted. Specifically, we examined the influence of the dark matter parameteron photon evolution by computing the shadow radius of the black hole. Our findings distinctly demonstrate thesignificant impact of the PFDM parameter α on the boundaries of this shadow, providing crucial insights into its featuresand interactions. We also provide profound insights into the intricate dynamics between a charged AdS blackhole, novel dark matter, and various physical phenomena, elucidating their interplay and contributing valuableknowledge to the understanding of these cosmic entities.
