The SKA-VLBI Perspective on Radio-Quiet AGN
Francesca Panessa, Tao An, James Petley +21
The accretion-ejection mechanism in Active Galactic Nuclei (AGN) remains a central open problem in astrophysics, tied to the role of AGN feedback in galaxy formation and evolution.…
Discovery of an extremely narrow trail-like feature crossing the Veil Supernova Remnant in deep amateur observations
David Martinez-Delgado, Jan-Niklas Pippert, Miguel A. Perez-Torres +9
We report the discovery of an extremely narrow and highly collimated gaseous trail-like structure crossing the eastern region of the Veil Nebula (Cygnus Loop). The feature was firs…
Unveiling multiple AGN activity in galaxy mergers
A. De Rosa, S. Bianchi, T. Bogdanovic +13
In this paper we present an overview of the MAGNA (Multiple AGN Activity) project aiming at a comprehensive study of multiple supemassive black hole systems. With the main goal to…
Subarcsecond international LOFAR radio images of Arp 220 at 150 MHz: A kpc-scale star forming disk surrounding nuclei with shocked outflows
E. Varenius, J. E. Conway, I. Martí-Vidal +16
We analyse new observations with the International Low Frequency Array (LOFAR) telescope, and archival data from the Multi-Element Radio Linked Interferometer Network (MERLIN) and…
23 GHz VLBI Observations of SN 2008ax
I. Marti-Vidal, J. M. Marcaide, A. Alberdi +14
We report on phase-referenced 23 GHz Very-Long-Baseline-Interferometry (VLBI) observations of the type IIb supernova SN 2008ax, made with the Very Long Baseline Array (VLBA) on 2 A…
