Parsec-scale polarimetry and kinematics of a spine-sheath jet in the neutrino-blazar TXS 0506+056
F. Eppel, P. Benke, C. Degli Agosti +10
In 2017, the blazar TXS 0506+056 showed a remarkable gamma-ray outburst simultaneously with a high-energy neutrino detection by IceCube from the same sky region. The significance o…
Radio properties of the quasi-periodic eruption source RXJ1301.9+2747 at parsec scales
S. D. von Fellenberg, R. Arcodia, P. Benke +6
Quasi-periodic eruptions (QPEs) are repeating soft X-ray flares associated with galactic nuclei. Several recent works have found evidence that the accretion flow in the galactic nu…
A helical magnetic field in quasar NRAO150 revealed by Faraday rotation
J. D. Livingston, A. S. Nikonov, S. A. Dzib +7
Active Galactic Nuclei (AGN) are some of the most luminous and extreme environments in the Universe. The central engines of AGN, believed to be super-massive black-holes, are fed b…
MOJAVE -- XXII. Brightness temperature distributions and geometric profiles along parsec-scale AGN jets
E. V. Kravchenko, I. N. Pashchenko, D. C. Homan +5
Radial gradients of the brightness temperatures along the parsec-scale jets of Active Galactic Nuclei (AGN) can be used to infer the energy balance and to estimate the parameter ra…
A multi-frequency study of sub-parsec jets with the Event Horizon Telescope
Jan Röder, Maciek Wielgus, Andrei P. Lobanov +287
The 2017 observing campaign of the Event Horizon Telescope (EHT) delivered the first very long baseline interferometry (VLBI) images at the observing frequency of 230 GHz, leading…
