Shadow and geometric scattering analysis of a new black hole with magnetic charge

We obtain a newly charged black hole with magnetic charge $q$ and coupling constant $\mu$ from the Einstein-nonlinear electrodynamics theory inspired by quasi-topological terms. We perform the shadow and geometric scattering analysis of this black hole. For $\mu =0.01$, we have four solution branches labelled by $2\pm$, 3, and 4 of the horizon, while there exists a single branch labelled by 2 for $\mu =0.1$. There is the naked singularity (NS) arisen from the magnetic charge extension of the photon spheres for the 3 and 4-branches. In case of $q<1$, shadow radii of the $2$-branch with $\mu$=0.01 and 0.1 are the same as that of the Reissner-Nordström black hole, while the 3-NS branch of $q>1$ is constrained by the EHT observation. The geometric scattering analysis is performed to understand the peculiar forms of the critical impact factors.
