Probing the -ray emission region and the connection to jet ejections in NRAO 150 with VLBI
L. C. Debbrecht, G. F. Paraschos, E. Ros +7
Relativistic jets launched by active galactic nuclei are fundamental for understanding the physics of accreting supermassive black holes and their immediate environments, yet the o…
Dynamics and geometry of the inner sub-parsec-scale jet in 3C 279 observed with the Event Horizon Telescope
Hendrik Mueller, Sebastiano D. von Fellenberg, Ai-Ling Zeng +275
The 2021 Event Horizon Telescope observations resolve the innermost jet region of the blazar 3C279 with unprecedented detail. The reconstructed images consistently reveal a compact…
Broadband multiwavelength properties of the archetypal blazar 3C 279 during the 2017 Event Horizon Telescope campaign
G. Principe, J. C. Algaba, E. Aviano +529
The archetypal blazar 3C 279 hosts a prominent relativistic jet and exhibits strong broadband variability across the electromagnetic spectrum. In April 2017, the Event Horizon Tele…
AGN Jets from Formation to Dissipation
A. -K. Baczko, Eleni Vardoulaki, Etienne Bonnassieux +26
Active Galactic Nuclei (AGN) are among the most energetic phenomena in the Universe, capable of launching powerful relativistic jets that extend from sub-parsec to megaparsec scale…
Relationship between the ray variability and the pc-scale jet in the blazar 3C 454.3
Eva Palafox, VÃctor Manuel Patiño-Ãlvarez, Vahram Chavushyan +3
3C 454.3 is a flat spectrum radio quasar (FSRQ) known for its high variability across the electromagnetic spectrum, showing structural and flux variability in its pc-scale jet, and…
Spectral index evolution of the limb-brightened jet in 3C 84
L. C. Debbrecht, G. F. Paraschos, E. Ros +11
Relativistic jets launched by active galactic nuclei are fundamental for understanding the physics of accreting supermassive black holes and their immediate environment, yet the me…
