Testing Lorentz Invariance with GRB021206
Steven E. Boggs, Cornelia B. Wunderer, Kevin Hurley +1
Since the discovery of the cosmological origin of GRBs there has been growing interest in using these transient events to probe the quantum gravity energy scale in the range 10^16-…
A close look at the state transitions of Galactic black hole transients during outburst decay
