Abstract
This paper explores the impact of the Yang–Mills charge parameter and the exponent term on a 4D black hole solution in the Einstein Power-Yang–Mills theory. Through an investigation of the massless scalar quasinormal mode spectrum, black hole shadow, and emission rate, we have determined that the effects of these two parameters are opposite. Specifically, the Yang–Mills charge parameter causes an increase in the real quasinormal frequencies with a correspondingly smaller damping rate. It also results in a smaller black hole shadow and a lower evaporation rate .
