Abstract:We report flux-resolved spectroscopic analysis of the active galactic nucleus (AGN) ESO 103-035 using NuSTAR observations. Following an earlier work, we fit the spectra using a thermal Comptonization model with a relativistic reflection component to obtain estimates of the coronal temperature for two flux levels. The coronal temperature was found to increase from 24.0 +6.8 −3.4 to 55.3 +54.6 −7.2 keV (errors at 1-σ confidence level) as the flux increased from 9.8 to 11.9 × 10 −11 erg cm −2 s −1 in the 3-78 keV… Show more
