Abstract

In strict analogy to prompt pulses, X-ray flares observed by Swift-XRT in long Gamma-Ray Bursts define a lag-luminosity relation: Lp, iso 0.3-10keV ∞ tlag-0.95±0.23 The lag-luminosity is proven to be a fundamental law extending ∼5 decades in time and ∼5 in energy. This is direct evidence that GRB X-ray flares and prompt gamma-ray pulses are produced by the same mechanism.
