Abstract The well-known correlation between radio luminosity (LR) and X-ray luminosity (LX), LR /LX≈10−5, holds for a variety of objects, such as active galactic nuclei, Galactic black holes, solar flares and cool stars. Here we extend the relation to gamma-ray bursts (GRBs) and find that the GRBs also obey a similar LR − LX relation, with a slightly different slope of LR ∝ LX1.1. This relation implies that the explosions that occur on different scales may have a common underlying origin.
