Investigating Equipartition Energy Parameters in TeV GRB1901114C

Abstract
GRB190114C was identified on on January 14th, 2019 with the peak emission of 0.2 to 1 TeV. The leading mechanism to explain Gamma-ray Bursts above the 10 GeV Synchrotron energy limit and the production of Very-High-Energy photons is Synchrotron self-Compton (SSC). Most current studies assume equipartition energy parameters, ϵe and ϵB, that are the fraction of energy in electrons and magnetic fields respectively, to remain constant with time in SSC dominated bursts. We analyse existing low-frequency power-law fitted Spectral Energy Distributions for GRB190114C reported in the analysis of MAGIC et al., (2019) to demonstrate that ϵe and the Compton Y parameter increase as ϵB decreases with time. The consideration of this evolution can improve the accuracy of predicted models of spectral evolution of bursts. Our findings contradict the current understanding of the dominance of the inverse Compton spectrum reducing in the late afterglow and the previously suggested possibility of ϵe decreasing and ϵB increasing with time.
