| Abstract: | Fast radio bursts (FRBs) are one of the most intriguing discoveries in the transient radio universe happened in the last two decades. FRBs are observed as short, a few milliseconds wide, radio bursts with typical fluences of the order of a few Jy ms. However, their cosmological distances imply that these short-lived events radiate enormous amount of energy, and the exact mechanism and origin of such energy release is still an active topic of research. To date many hundreds of FRBs have been reported to be discovered (the actual number is potentially a few thousands but not published yet). A small fraction of these, called repeating FRBs, have been found to repeat. These repeating FRBs enable their precise localization using sensitive interferometeric telescopes, and hence, a multitude of probes, including multi-wavelength follow ups and deep searches for potential existence of their radiative environments. Such probes have resulted in to detection of persistent radio emission (PRS) associated with a few repeating FRBs so far. The observed PRSs have been found to be highly compact and provide a crucial clue to the central engine that is responsible for the FRB emission. I will provide a brief review of the worldwide efforts towards understanding the origin of FRBs, including our own recent results in this direction. |
