Abstract
ABSTRACT Both gamma-ray bursts (GRBs) and pulsar wind nebula (PWNe) are energetic outflows that are produced in powerful high-energy astrophysical environments. Based on the correlations between the radio luminosity LR and X-ray luminosity LX as well as between the multiband spectral slope αRX and radio flux FR for compiled GRB and PWN samples, the radio and X-ray spectral properties are statistically investigated. The results show that (1) the correlations between LR and LX are consistent for GRBs and PWNe, within the uncertainties; and (2) for the whole sample, FR is related to αRX, and GRBs have lower αRX than PWNe. It may be concluded that GRBs and PWNe have the same or similar particle acceleration mechanisms and radiation processes, i.e. synchrotron radiation, to produce the radio-to-X-ray band emission.
