Relativistic jets in active galactic nuclei and microquasars

GE Romero, M Boettcher, S Markoff… - Space Science Reviews, 2017 - Springer
Collimated outflows (jets) appear to be a ubiquitous phenomenon associated with the
accretion of material onto a compact object. Despite this ubiquity, many fundamental physics …

Dynamically important magnetic fields near accreting supermassive black holes

M Zamaninasab, E Clausen-Brown, T Savolainen… - Nature, 2014 - nature.com
Accreting supermassive black holes at the centres of active galaxies often produce 'jets'—
collimated bipolar outflows of relativistic particles. Magnetic fields probably play a critical …
