Very Long Baseline Interferometry with the SKA Observatory

J. F. Radcliffe, J. Yang, Z. Paragi +129

Very Long Baseline Interferometry (VLBI) is a fundamental technique that combines signals from telescopes separated by thousands of kilometres to obtain some of the highest-resolut…

Comparing the size evolution of GRB 221009A with afterglow models

S. Giarratana, O. S. Salafia, B. Marcote +10

We present very long baseline interferometry (VLBI) observations of GRB221009A obtained with the global-VLBI network at 5 GHz between 231 and 750 days after the burst. The quality…

Fast radio burst - persistent radio source systems II. A faint PRS associated with the nearby FRB 20181030A?

D. Pelliciari, G. Bernardi, B. Margalit +10

Persistent radio sources (PRSs) are the continuum counterparts of fast radio bursts (FRBs), the latter being extragalactic transients of millisecond duration and Jy-level flux dens…

Observational Evidence of an Internal Shock Collision in the Relativistic Jet of the Nearby Radio Galaxy 3C 111

Kenzo Kawamura, Motoki Kino, Mareki Honma +21

We report 10 epochs of 22 GHz East Asia To Italy: Nearly Global VLBI (EATING VLBI) observations of the nearby radio galaxy 3C~111 obtained from 2020 to 2023. Combined with VLBA dat…

Colour evolution in the radio afterglow of GRB 241025A

S. Giarratana, O. S. Salafia, L. Nava +10

We present the observing campaign of the afterglow of GRB241025A, a gamma-ray burst (GRB) whose prompt emission has been simultaneously detected by Swift, Einstein Probe, Fermi/GBM…

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.…
