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…
RadioAstron reveals a change in the jet collimation profile of 3C 84
P. Benke, T. Savolainen, G. Giovannini +5
Due to its brightness and proximity, the radio galaxy 3C 84 (optical counterpart NGC 1275 in the Perseus cluster) has been the target of extensive studies investigating the central…
Rapid jet ejection from PKS 0215+015 coincident with a high-energy neutrino event
F. Eppel, M. Kadler, E. Ros +19
Aims. We present a new neutrino-blazar multiwavelength flare coincidence observed in the blazar PKS 0215+015, which showed a strong multiwavelength outburst in coincidence with the…
Shared-optical-path VLBI frequency phase transfer from 86 to 258 GHz on an 8600 km baseline: Demonstrated with the APEX and IRAM 30 m telescopes
G. -Y. Zhao, A. L. Roy, J. F. Wagner +24
The receiver N3AR operating at a frequency range between 67 and 116 GHz has been commissioned at the APEX telescope in October 2024. This adds a new low-frequency band for APEX, wi…
Probing the innermost regions of AGN jets and their magnetic fields with RadioAstron II. Observations of 3C 273 at minimum activity
G. Bruni, J. L. Gómez, C. Casadio +18
RadioAstron is a 10 m orbiting radio telescope mounted on the Spektr-R satellite, launched in 2011, performing Space Very Long Baseline Interferometry (SVLBI) observations supporte…
Discovery of off-axis jet structure of TeV blazar Mrk 501 with mm-VLBI
S. Koyama, M. Kino, M. Giroletti +10
High-resolution millimeter wave very-long-baseline interferometry (mm-VLBI) is an ideal tool for probing the structure at the base of extragalactic jets in detail. The TeV blazar M…
