Optically Thick Jet Base and Explanation of Edge Brightening in Active Galactic Nucleus Jets

Autor: Mukesh Kumar Vyas, Asaf Pe’er

Publikováno v: The Astrophysical Journal, Vol 972, Iss 1, p 40 (2024)

The jet cores in active galactic nuclei (AGNs) are resolved and found to harbor an edge-brightened structure where the jet base appears extended at the sides compared to its propagation axis. This peculiar phenomenon invites various explanations. We

Implications and improvements of edge brightening effects led by $Q$ factor minimization restricted to keep the same level of directivity for high efficiency continuous circular aperture distributions are here reported. In this manner, an optimizatio
