Investigating the existence of gravitomagnetic monopole in M87*

Abstract We examine the possibility for the existence of gravitomagnetic monopole ( $$n_*$$ n ∗ ) in M87* by using the results obtained from its first Event Horizon Telescope image. By numerically deducing the shadow sizes in Kerr-Taub-NUT (KTN) spacetime, we show that the shadow size increases with...
