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…
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…
Probing jet base emission of M87* with the 2021 Event Horizon Telescope observations
Saurabh, Hendrik Müller, Sebastiano D. von Fellenberg +282
We investigate the presence and spatial characteristics of the jet base emission in M87* at 230 GHz, enabled by the enhanced uv coverage in the 2021 Event Horizon Telescope (EHT) o…
Catching the 2021 γ-ray flare in the blazar TXS 2013+370
Giorgos Michailidis, Efthalia Traianou, Nicola Marchili +8
The -ray-loud blazar TXS 2013+370, a powerful multiwavelength emitter at , underwent an exceptional GeV outburst in late 2020-early 2021. In this work, we present ful…
Twenty years of blazar monitoring with the INAF radio telescopes
N. Marchili, S. Righini, M. Giroletti +14
The extreme variability of blazars, in both timescale and amplitude, is generally explained as the effect of a relativistic jet closely aligned to the observer's line-of-sight. Due…
A milliarcsecond localization associates FRB 20190417A with a compact persistent radio source and an extreme magneto-ionic environment
Alexandra M. Moroianu, Shivani Bhandari, Maria R. Drout +38
We report the milliarcsecond localization of a high (1379 pc/cc) dispersion measure (DM) repeating fast radio burst, FRB 20190417A. Combining European VLBI Network detections of fi…
