Reading M87's DNA: A Double Helix revealing a large scale Helical Magnetic Field
Alice Pasetto, Carlos Carrasco-Gonzalez, Jose L. Gomez +7
We present unprecedented high fidelity radio images of the M87 jet. We analyzed Jansky Very Large Array (VLA) broadband, full polarization, radio data from 4 to 18 GHz. The observa…
Polarimetric properties of Event Horizon Telescope targets from ALMA
Ciriaco Goddi, Ivan Marti-Vidal, Hugo Messias +31
We present the results from a full polarization study carried out with ALMA during the first VLBI campaign, which was conducted in Apr 2017 in the 3mm and 1.3mm bands, in con…
Parsec-scale properties of the peculiar gigahertz-peaked spectrum quasar 0858-279
N. A. Kosogorov, Y. Y. Kovalev, M. Perucho +1
We performed multi-frequency studies on the gigahertz-peaked spectrum high-redshift quasar 0858-279. Initially, the source presented itself in the early VLBI images as a very pecul…
RadioAstron reveals a spine-sheath jet structure in 3C 273
G. Bruni, J. L. Gómez, L. Vega-García +13
We present Space-VLBI RadioAstron observations at 1.6 GHz and 4.8 GHz of the flat spectrum radio quasar 3C 273, with detections on baselines up to 4.5 and 3.3 Earth Diameters, resp…
Multiband RadioAstron space VLBI imaging of the jet in quasar S5 0836+710
L. Vega-García, A. P. Lobanov, M. Perucho +11
Detailed studies of relativistic jets in active galactic nuclei (AGN) require high-fidelity imaging at the highest possible resolution. This can be achieved using very long baselin…
Radio source evolution and the interplay with the host galaxy
Manel Perucho
There is compelling evidence showing that extragalactic jets are a crucial ingredient in the evolution of host galaxies and their environments. Extragalactic jets are well collimat…
Asymmetric jet production in the Active Galactic Nucleus of NGC1052
A. -K. Baczko, R. Schulz, M. Kadler +4
Context: Few Active Galactic Nuclei (AGN) reveal a double sided jet system. However, these are crucial to understand basic physical properties of extragalactic jets. Aims: We addre…
Long-term FRII jet evolution: Clues from three-dimensional simulations
Manel Perucho, José-María Martí, Vicent Quilis
We present a long-term numerical three-dimensional simulation of a relativistic outflow designed to be compared with previous results from axisymmetric, two-dimensional simulations…
Radio source evolution
Manel Perucho
Baldwin (1982) wrote that \emph{the distribution of sources in the radio luminosity, , overall physical size, , diagram} could be considered as \emph{the radio astronomer's $…
On the location of the supermassive black hole in CTA 102
C. M. Fromm, M. Perucho, E. Ros +2
Relativistic jets in active galactic nuclei represent one of the most powerful phenomena in the Universe. They form in the surroundings of the supermassive black holes as a by-prod…
