Multi-band Cross-correlated Radio Variability of the Blazar 3C 279
Krishna Mohana A, Alok C. Gupta, Alan P. Marscher +18
We present the results of our study of cross-correlations between long-term multi-band observations of the radio variability of the blazar 3C 279. More than a decade (2008-2022) of…
Filamentary structures as the origin of blazar jet radio variability
Antonio Fuentes, José L. Gómez, José M. Martí +22
Supermassive black holes at the centre of active galactic nuclei power some of the most luminous objects in the Universe. Typically, very long baseline interferometric (VLBI) obser…
Probing neutrino production in blazars by millimeter VLBI
Y. Y. Kovalev, A. V. Plavin, A. B. Pushkarev +1
The advancement of neutrino observatories has sparked a surge in multi-messenger astronomy. Multiple neutrino associations among blazars are reported while neutrino production site…
Properties of the jet in M87 revealed by its helical structure imaged with the VLBA at 8 and 15 GHz
A. S. Nikonov, Y. Y. Kovalev, E. V. Kravchenko +2
We present full-track high-resolution radio observations of the jet of the galaxy M87 at 8 and 15 GHz. These observations were taken over three consecutive days in May 2009 using t…
Key Science Goals for the Next-Generation Event Horizon Telescope
Michael D. Johnson, Kazunori Akiyama, Lindy Blackburn +42
The Event Horizon Telescope (EHT) has led to the first images of a supermassive black hole, revealing the central compact objects in the elliptical galaxy M87 and the Milky Way. Pr…
RadioAstron Space VLBI Imaging of the jet in M87: I. Detection of high brightness temperature at 22 GHz
Jae-Young Kim, Tuomas Savolainen, Petr Voitsik +19
We present results from the first 22 GHz space very-long-baseline interferometric (VLBI) imaging observations of M87 by RadioAstron. As a part of the Nearby AGN Key Science Program…
