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…

A Repeating Fast Radio Burst Source in a Low-Luminosity Dwarf Galaxy

Danté M. Hewitt, Mohit Bhardwaj, Alexa C. Gordon +48

We present the localization and host galaxy of FRB 20190208A, a repeating source of fast radio bursts (FRBs) discovered using CHIME/FRB. As part of the PRECISE repeater localizatio…

Proper motion of the radio jets in two blazars at redshift above 3

Mate Krezinger, Sandor Frey, Krisztina Perger +7

There is still a limited number of high-redshift () active galactic nuclei (AGN) whose jet kinematics have been studied with very long baseline interferometry (VLBI). Without…

Astrometric Apparent Motion of High-redshift Radio Sources

Oleg Titov, Sandor Frey, Alexei Melnikov +10

Radio-loud quasars at high redshift (z > 4) are rare objects in the Universe and rarely observed with Very Long Baseline Interferometry (VLBI). But some of them have flux density s…
