Multi-wavelength afterglows of fast radio bursts
arXiv:1407.0348 · doi:10.1088/2041-8205/792/1/L21
Abstract
The physical nature of fast radio bursts (FRBs) is not identified. Detecting electromagnetic counterparts in other wavelengths is essential to measure their distances and to settle down their physical nature. Assuming that at least some of them are of a cosmological origin, we calculate their afterglow lightcurves in multi-wavelengths (X-rays, optical and radio) by assuming a range of their total kinetic energies and redshifts. We focus on forward shock emission, but also consider the possibility that some of them might have bright reverse shock emission. In general, the FRB afterglows are too faint to be detected by current detectors. Only if an FRB has a very low radiative efficiency in radio (hence, a very large kinetic energy), and when it is close enough, can its afterglow be detected in the optical and radio bands. We discuss observational strategies to detect these faint afterglows using future telescopes such as LSST and EVLA.
