Strong Lensing of Explosive Transients

Abstract: Recent rapid progress in time domain surveys makes it possible to detect various types of explosive transients (Gamma-ray bursts, Gravitational wave, supernovae, and Fast radio bursts) in the Universe in large numbers, some of which will gravitationally lensed into multiple images. Although a large number of strongly lensed distant galaxies and quasars have already been discovered, strong lensing of explosive transients opens up new applications, including improved measurements of cosmological parameters and powerful probes of small scale structures of the Universe, thanks to their rapidly evolving light curves as well as their compact sizes. Recently we have witnessed first discoveries of strongly lensed supernovae, and strong lensing events of other types of explosive transients are expected to be observed soon. In this presentation, I will review a recent paper on the current state of research on strong gravitational lensing of explosive transients and discuss future prospects.
