Description
In our presentation, we demonstrate the spacetime properties of a monopole within nonlinear $\sigma$-models in Eddington inspired Born-Infeld gravity. Specifically, we investigate characteristic circular orbits of test particles and photons, including circular null geodesics, marginally bound orbits, and stable circular orbits, as influenced by spacetime parameters. Additionally, we discuss the dynamics of a massless scalar field, covering quasinormal frequencies in both low and high energy regimes, their time evolutions, and the stability of the configuration against scalar perturbations.
