Top: SED of the X-ray emission of NGC 4190 ULX-1 on a logarithmic scale. We plot the radiation from the innermost part of the disk that escapes through the funnel (blue line) and the radiation produced by Comptonization of the disk emission by nonthermal electrons in the funnel (orange line). The black line represents the total SED, while red dots correspond to energy-binned observations from NICER and NuSTAR. We also present, for comparison, the application of our model assuming an accretion rate of 1 Ṁ_Edd (dashed lines) and of 15 Ṁ_Edd (dash-dotted lines). Bottom: residuals of the best fit. The six spectral bins correspond to the data in the 0.4 − 20 keV energy range.
