A Particle Detector Array deployed to the Murchison Widefield Array in the Murchison Radio-astronomy Observatory

J. E. Dickinson, J. D. Bray, D. Kenney +16

We report the design and functionality of the Murchison Widefield Array Particle Detector Array (MWA PDA), an array of eight particle scintillation detectors deployed to Inyarriman…

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).…

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…
