Abstract

The European VLBI Network (EVN) has been used successfully in the past to precisely localise repeating fast radio bursts (FRBs) to study their host galaxies and local environments. To date, our team has precisely localised five repeating FRBs using the EVN (two published, two pre-print/ATel and one unpublished) and uncovered a diverse host galaxy and local environment characterisation for repeating FRBs. The high spacial precision afforded by the EVN is a requirement for studying the FRB's immediate environment, which is crucial for understanding what type(s) of objects can produce FRBs. We propose to observe a list of repeating FRB sources with current ~arcminute localisations, to precisely localise to ~milliarcsecond precision in order to characterise the host galaxy and local environment. This is a natural continuation of our previous monitoring campaigns (PI Nimmo; EN005, EN007), but with a more extensive source list and using real-time activity alerts from other instruments to increase our chances of detection.
