Description
Multiwavelength polarimetric studies provide a powerful tool to probe the structure and physics of blazar jets, and in particular high-energy polarisation measurements allow us to discriminate between competing models for their multimessenger emission. A new generation of X-ray and gamma-ray polarimeters is currently under development to achieve that. In this work, we investigate the detectability of blazar polarisation as a function of flux and polarisation degree (PD), and we estimate the corresponding duty cycle expected for future instruments. We further explore how this duty cycle depends on SED class, typical variability levels, and the shape of the synchrotron component. This provides a unified way to compare theoretical expectations with real observing capabilities and to assess which sources, physical models, and flux states are most favourable for polarimetric studies. Our results offer practical guidelines for planning future multiwavelength polarisation campaigns to conclusively differentiate between competing theories.
