Gamma-ray bursts and their afterglows are the result of intense explosions at cosmological distances, related to the core collapse of massive stars and possibly to the coalescence of compact binary systems. I will begin this review by summarizing the progress in our understanding of gamma-ray bursts, their progenitors, central engines and their host galaxies in the two years since the launch of the multi-wavelength Swift Observatory. I will focus the remaining part of the review on unanswered questions, pointing out where ALMA and the EVLA may be able to make significant contributions.
