Description
A handful of repeating Fast Radio Bursts (FRBs) have been found to be spatially associated with a compact persistent radio source (PRS). Observational evidence suggests that the continuum emission of PRSs originates from a nebula embedding either a magnetar or a binary system of compact objects. Therefore, PRSs are crucial targets to investigate the progenitors of FRBs and their formation channel. We followed-up a sample of 18 well-localized repeaters and one-off FRBs with sensitive ($10 \; \mu Jy \; beam^{-1}$) and high-resolution ($\sim 2’’$) uGMRT observations to search for possible PRSs. I will present preliminary results from such observing campaign, focusing on the comparison of our detections and upper limits with the properties of known PRSs in the literature.
