Probing the multiwavelength emission scenario of GRB 190114C

ABSTRACT Multiwavelength observation of the gamma-ray burst, GRB 190114C, opens a new window for studying emission mechanism afterglows. Its very high energy (VHE; ≳ 100 GeV) detection has motivated an inverse Compton interpretation emission, but this not been tested. Here, we revisit early afterglow from 68 to 180 s and perform modelling likelihood analysis with keV TeV data sets. We compute first time statistical preference in combined synchrotron (syn) self-Compton (SSC) model over syn-only model. In agreement earlier analyses, between 110 unstable SSC can be found, which also explained by systematic cross-calibration effect included instruments. conclude that there is no stable one two models.
