Relativistic jets from active galactic nuclei

R Blandford, D Meier… - Annual Review of …, 2019 - annualreviews.org
The nuclei of most normal galaxies contain supermassive black holes, which can accrete
gas through a disk and become active. These active galactic nuclei (AGNs) can form jets that …

First Sagittarius A* event horizon telescope results. V. Testing astrophysical models of the galactic center black hole
