Constraint on Lorentz Invariance Violation for spectral lag transition in GRB 160625B using profile likelihood

Shantanu Desai, Shalini Ganguly

We reanalyze the spectral lag data for GRB 160625B using frequentist inference in order to constrain the energy scale ($E_{QG}$) of Lorentz Invariance Violation (LIV). For this pur…
