Unveiling the origin of fast radio bursts

Fast radio bursts (FRBs) are a new and exciting class of highly energetic extragalactic transients of unknown origin. Significant progress has been made to increase the number of detections over the past couple of years. Despite the growing FRB population, major questions remain about their mysterious origin: do all FRBs repeat? Is there more than one way to produce an FRB? Are there multiple progenitors? In this talk, I discuss the different approaches we can take to tackle these questions that are currently driving the field. I will focus particularly on multi-wavelength/messenger observations and the growing number of FRBs with host galaxy associations. I will draw on my research, which includes targeted FRB searches with the Low Frequency Array (LOFAR) triggered by gamma-ray bursts and gravitational waves, deep studies of the first FRB source discovered to repeat, and comparison of localized FRBs to viable origin theories.
