Landing page for project EK051

The CHIME/FRB collaboration has published 20 repeating fast radio burst (FRB) sources, and a further 17 unpublished ones are know to our group via a MoU. The majority of the repeaters are at high declination (>60 degrees), i.e. they are circumpolar for many European stations. We are continuing our campaign with an ad-hoc VLBI array (On, Tr, Ir, Mc, Nt, Ur, Wb, Ef, Sr, eMERLIN, Gb, Ro70) that regularly (10 -- 16 hours per week) monitors these FRBs, aiming to localise them with sub-arcsecond precision. We search the baseband data for bursts with a custom pipeline, turn around times are of order a week. Here we ask for correlation of our data in the event that we detect a burst of any of the FRBs in our VLBI recordings. This strategy lead to the published localisation of two FRBs -- with three more underway, effectively tripling the number of FRBs with a mas-localisation. Previous iterations of this project have lead to several high impact publications, including ones in Nature and Nature Astronomy. We estimate that we can detect up to 10 FRBs over the course of one year, hence ask for 10 triggered correlator runs.

This data is part of the archive of VLBI data maintained by JIVE on behalf of the EVN, a network of radio telescopes located primarily in Europe and Asia, with additional antennas in South Africa. The EVN archive itself has the DOI https://doi.org/10.17616/R3Z197
