Hard X-Ray View of Two Extreme Blazars

Utilizing the NuSTAR telescope, we study the hard x-ray spectrum of 1ES 0229+200 and H1426+428 using data collected during flaring and non-flaring periods. The data were cleaned and calibrated using NuSTARDAS software. Hard x-ray observations of similar sources have shown that the synchrotron radiation mirrors inverse Compton scattering, thus the study of high-energy x-rays can potentially provide more insight into the behavior of high-energy gamma-rays. We compare the observations of the flaring and non-flaring states, finding that for the two observations of H1426+428, the low state shows curvature, peaking at 10 kev, while the synchrotron emission of the high state peaks above 10 kev and shows no curvature. 1ES 0229+200, observed six times over two epochs, displays only marginal variability, with a spectrum that can be well described with a log-parabolic model, peaking beyond 10 keV.
