A milliarcsecond localization associates FRB 20190417A with a compact persistent radio source and an extreme magneto-ionic environment
Alexandra M. Moroianu, Shivani Bhandari, Maria R. Drout +38
We report the milliarcsecond localization of a high (1379 pc/cc) dispersion measure (DM) repeating fast radio burst, FRB 20190417A. Combining European VLBI Network detections of fi…

A Hyperactive FRB Pinpointed in an SMC-Like Satellite Host Galaxy
M. Bhardwaj, M. P. Snelders, J. W. T. Hessels +24
Precise localizations of fast radio bursts (FRBs) are essential for uncovering their host galaxies and immediate environments. We present the milliarcsecond-precision European VLBI…

Revisiting FRB 20121102A: milliarcsecond localisation and a decreasing dispersion measure
M. P. Snelders, J. W. T. Hessels, J. Huang +27
FRB 20121102A is the original repeating fast radio burst (FRB) source and also the first to be localised to milliarcsecond precision using very-long-baseline interferometry (VLBI).…
