论文摘要
最近在GRB文献中对两种单独的长期伽马射线爆发（LGRB）的存在，有或没有无线电余潮排放，与无线电余潮排放相对应，与无线电/响亮的无线电和宁静种群相对应，在GRB文献中被争辩并受到青睐。已发现无线电广播LGRB的总各向同性伽马射线排放（EISO）和较短的固有及格及时伽马射线持续时间（例如T90Z）。此外，在Radio-Loud LGRB中发现了红移T90Z的抗相关性，据报道，这在无线电Quiet类中缺少。 在这里，我们讨论了两个拟议的无线电和射电Quiet LGRB的能量和时间特性之间差异的重要性。我们表明，在选择效果和样本不完整方面，可以解释许多支持LGRB两个不同无线电种群的建议证据。我们的论点是基于最近发现的相对较高的高度显着性正相关（EISO）与固有的及时及时持续时间（T90Z）之间的相对显着的正相关，这些持续时间（T90Z）都存在于短措施和长期GRB中，并在Shahmoradi（2013和2013年）和Shahmoradi（2013年）和Shahhmoradi（2013年）首次报道了Shahmoradi（2013年）。
The potential existence of two separate classes of Long-duration Gamma-Ray Bursts (LGRBs) with and without radio afterglow emission, corresponding to radio-bright/loud and radio-dark/quiet populations, has been recently argued and favored in the GRB literature. The radio-quiet LGRBs have been found to have, on average, lower total isotropic gamma-ray emissions (Eiso) and shorter intrinsic prompt gamma-ray duration (e.g., T90z). In addition, a redshift-T90z anti-correlation has been discovered among the radio-loud LGRBs, which is reportedly missing in the radio-quiet class. Here we discuss the significance of the differences between the energetics and temporal properties of the two proposed classes of radio-loud and radio-quiet LGRBs. We show that much of the proposed evidence in support of the two distinct radio populations of LGRBs can be explained away in terms of selection effects and sample incompleteness. Our arguments are based on the recent discovery of the relatively-strong highly-significant positive correlation between the total isotropic emission (Eiso) and the intrinsic prompt duration (T90z) that is present in both populations of short-hard and long-soft GRBs, predicted, quantified, and reported for the first time by Shahmoradi (2013) and Shahmoradi and Nemiroff (2015).
