Fast Radio Bursts (FRBs) are millisecond-long, bright radio flares predominantly originating from cosmological distances, whose origin is still largely unknown. Recent observations revealed continuum (persistent) radio sources (PRSs) associated with a few repeating FRBs. The PRS/FRB association helps shedding light on the nature of the FRB enviroment (i.e. where they form) and may even help to constrain the nature of the FRB sources themselves. However, very little is currently known about PRSs to date. In the last year, we began to construct a catalog of FRBs observed at arcsecond angular scales. In this proposal we intend to conduct follow-up observations of five potential PRSs at 1.4 GHz, aimed at confirming their compact nature on pc linear scales. Moreover, we ask additional observations of a sixth source, i.e. the already confirmed PRS associated with the hyperactive FRB 20240114A. Our observations will shed light on its physical properties by searching for a characteristic peak in its radio spectrum, which in turn would confirm a nebular origin.
