Testing two-component models on very-high-energy gamma-ray emitting BL Lac objects

Understand

Context.

• It has become evident that one-zone synchrotron self-Compton models are not always adequate for very-high-energy (VHE) gamma-ray emitting blazars.
• While two-component models are performing better, they are difficult to constrain due to the large number of free parameters.
• Aims.
