Advances in Fast Radio Burst Localization with VLBI: Insights from Recent Developments
Content
Fast Radio Bursts (FRBs) have emerged as one of the most enigmatic phenomena in modern astrophysics, characterized by their millisecond-duration flashes of extreme luminosity originating from cosmological distances. Despite significant progress in the field, the exact nature and progenitors of FRBs remain elusive. Our group has made substantial advancements in the precise localization of FRBs using Very Long Baseline Interferometry (VLBI), leveraging the unparalleled resolution and sensitivity of the European VLBI Network (EVN). These efforts have enabled us to localize the millisecond-duration bursts to milliarcsecond precision, and directly image the persistent radio sources associated with some FRBs. These findings provided critical insights into their environments and potential progenitors, such as young magnetars, superluminous supernovae, and massive black hole systems. In this talk, I will present the latest results from our VLBI observations within the PRECISE and AstroFlash/EuroFlash activities. By combining multi-wavelength data and theoretical modeling, we have been able to differentiate between various formation channels and evolutionary stages of FRB sources. Our findings not only shed light on the physical conditions required to produce these bursts but also pave the way for future research with next-generation facilities. This work represents a significant step forward in understanding the origins and mechanisms of FRBs, contributing to the broader field of astrophysics and cosmology.
