Modeling the imprints of large-scale magnetized structures on -rays from extragalactic transients

Saikat Das, Soebur Razzaque, Nestor Mirabal +3

In the multimessenger era, the association of high-energy transients with their -ray counterparts can be obscured by magnetized large-scale structure surrounding the source. We…
