We examine GRB radio light curves (LCs) to look for the presence of radio plateaus resembling the plateaus observed at X-ray and optical wavelengths. We analyze 404 GRBs from the literature with observed radio afterglow and fit 82 GRBs with at least five data points with a broken power-law model, requiring four parameters. From these, we find 18 GRBs that present a break feature resembling a plateau. We conduct the first multiwavelength study of the Dainotti correlation between the luminosity La and the rest-frame time of break Ta* for those 18 GRBs, concluding that the correlation exists and resembles the corresponding correlation at X-ray and optical wavelengths after correction for evolutionary effects. We compare Ta* for the radio sample with Ta* values in X-ray and optical data, finding significantly later break times in the radio. We propose that this late break time and the compatibility in slope suggest either a long-lasting plateau or the passage of a spectral break in the radio band. We also correct the distribution of the isotropic energy Eiso versus the rest-frame burst duration T*90 for evolutionary effects and conclude that there is no significant difference between the T*90 distributions for the radio LCs with a break and for those without.2022ApJ...925...15Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/925/15CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/418/2202 : Analysis of {gamma}-ray bursts (Dainotti+, 2011)J/ApJ/746/156 : Radio afterglow observations of GRBs (Chandra+, 2012)J/ApJ/774/157 : Swift GRBs with X-ray afterglows and z<9.5 (Dainotti+, 2013)J/ApJ/781/37 : Multi-band photometry of GRB 130427A (Perley+, 2014)J/ApJ/814/1 : GRB 120326A, 100418A & 100901A obs.
