Description
In anticipation of the Square Kilometre Array Observatory, especially its lower range components coming online in the next few years, it is expected that this radio telescope is sensitive enough to detect radio signals from pulsars at greater distances in the universe. Particularly pulsars close to the SMBH Sgr A* are of great interest as time delay effects from their signals can give greater insights into the strong gravity environment around SMBHs. As pulsars emit detectable signals at lower frequencies, plasma effects on the propagation of photons may play a significant role in expectations of pulsar signal detection around SMBH. The properties of the accretion disks around SMBH and the dispersion relation of the plasma hinge on the same assumptions, which we are probing in raytracing simulations of these objects, with as final goal to simulate orbits of pulsars around the SMBH with plasma effects taken into account.
