The intrinsic luminosity-decay correlation in subsamples of GRB X-ray afterglows

S. P. R. Shilling, S. R. Oates, J. L. Racusin +6

The intrinsic luminosity-decay correlation in gamma-ray burst (GRB) afterglows, between the early-time luminosity and the average rate of decay past this time, has previously been…
