The mechanism responsible for the prompt emission of gamma-ray bursts (GRBs) is still a debated issue. The prompt phase-related GRB correlations can allow discriminating among the most plausible theoretical models explaining this emission. We present an overview of the observational two-parameter correlations, their physical interpretations, and their use as redshift estimators and possibly as cosmological tools. The nowadays challenge is to make GRBs, the farthest stellar-scaled objects observed (up to redshift ), standard candles through well established and robust correlations. However, GRBs spanning several orders of magnitude in their energetics are far from being standard candles. We describe the advances in the prompt correlation research in the past decades, with particular focus paid to the discoveries in the last 20 years.

伽马射线爆发提示相关

负责迅速发射伽马射线爆发（GRB）的机制仍是一个有争议的问题。迅速的与相位相关的GRB相关性可以区分出最合理的解释此排放的理论模型。我们概述了观测的两参数相关性，它们的物理解释以及它们作为红移估计量和可能作为宇宙学工具的用途。如今的挑战是制造GRB，这是观测到的最远的恒星尺度物体（直到红移），标准蜡烛，并建立了完善且稳健的相关性。但是，GRB的能量学跨越几个数量级，远非标准蜡烛。我们描述了过去数十年中快速相关性研究的进展，特别关注了过去20年中的发现。
