Observed SED for NGC 1052 at subarsec (black circles) and low-angular resolution (grey spikes) compared with the predicted self-absorbed synchrotron plus associated inverse Compton (IC) emission for two particle distributions: a Maxwell-Jüttner energy distribution (dashed green line), representative of a thermalised distribution of relativistic electrons; and a power law energy distribution with a steep index, p = 6.3 (solid pink line; see Eq. (2)). For comparison, the continuum spectrum expected for a power-law energy distribution with p = 2.4 (F_ν ∝ ν^−0.7) is also shown (dotted grey line).
