Description
Fast Radio Bursts (FRBs) are bright, millisecond radio pulses occurring at cosmological distances. The nature of these sources is still unknown. Upon localisation of the repeating FRBs, luminous compact persistent radio sources (PRSs) can be detected in some cases. Studying the PRSs may give us clues about the immediate environments of the FRBs, which in turn provides insights into the nature of the FRB sources. However, the origin of the PRSs is also unknown. This work uses the MeerKAT telescope to search for PRS candidates towards selected FRB positions localised by ASKAP and MeerTRAP. We are also constructing a theoretical model of a magnetar wind nebula (MWN) to model the spectrum and frequency-dependent surface brightness profile of the PRS and the evolution of the dispersion measure and rotation measure. The proposed model is an attempt to explain the origin of faint PRSs and how they are associated with FRBs. This presentation summarises our recent progress and highlights ongoing and planned research directions.
