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…
Constraining the jet base emission of M87* with past and future Event Horizon Telescope observations
Noemi La Bella, Michael Janssen, Britton Jeter +5
We investigate the detectability of the jet base of M87* at Event Horizon Telescope (EHT) observing frequencies. Although M87 is known to host a prominent relativistic jet, detecti…
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…
Probing anisotropic particle acceleration and limb-brightening in Centaurus A's jet
Felix Glaser, Christian M. Fromm, Luca Ricci +4
Relativistic jets are among the most fascinating objects in the Universe, and recent high-resolution Very Long Baseline Interferometric (VLBI) observations, including the Global mm…
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…
Locating the missing large-scale emission in the jet of M87* with short EHT baselines
Boris Georgiev, Paul Tiede, Sebastiano D. von Fellenberg +280
In Very-Long Baseline Interferometric arrays, nearly co-located stations probe the largest scales and typically cannot resolve the observed source. In the absence of large-scale st…
