Abstract

The European VLBI Network (EVN) has been used successfully in the past to precisely localise bursts (to a specific star-forming region within its host galaxy) from the first repeating fast radio burst (FRB) source, FRB 121102, and to study its persistent radio counterpart. More recently, our group used the EVN to precisely localise a second repeating FRB, FRB 180916.J0158+65. The environment of this source contrasts with what is observed in the case of FRB 121102, but also contrasts with what is observed in the only localised so-far non-repeating FRBs. This result shows that FRBs can reside in a diverse set of host galaxies and local environments. Future precise localisations of FRBs are crucial in understanding the FRB population, and to constrain progenitor models. We propose to observe a list of FRB sources with the EVN with a goal to precisely localise the bursts to ~milliarcsecond precision. This is a natural continuation of our previous proposal (Project code: EN005; PI: Nimmo), with the same science objective, but with the difference of a new source list with both repeating and potentially repeating FRB sources that have a-priori positions accurate to within a few arcminutes.
