Description

The study of black hole shadows after the discovery of the M87 black hole by the Event Horizon Telescope (EHT) has gained major interest recently. In this work, we have studied the shadows of a renormalization group improved (RGI) black hole system surrounded by two types of plasma media, viz homogeneous and inhomogeneous plasma. We have found that the associated free parameter $\xi$ related to the momentum cutoff scale plays a significant role in determining the photon sphere radius and hence the black hole shadows.

Keywords: Black Hole Shadows, Renormalisation Group (RG), Plasma
