Description
Deep investigation of the environment where the bursts occur is the most promising way to shed light on these mysterious phenomena. Observations of a handful of events indicated different progenitor channels, yielding to distinct location, local environment and host galaxy properties. The recent discovery of a persistent radio source associated with FRB 20201124A and 20240114A supports the nebular model for the continuum emission, circumscribing the progenitors to magnetars (favoured) or hyperaccreting X-ray binaries. In the near future, the advent of new dedicated radio facilities will deliver dozens of arcsec-level localized FRBs per year, improving the statistics on host galaxies and continuum counterparts. The talk aim at reviewing current developments and future prospects of PRS characterisation.
