Description
The blazar OT 081 was detected only once in the very-high-energy gamma-rays range, by MAGIC and H.E.S.S. telescopes. The multiwavelength (MWL) data collected in that single opportunity, and reported in a recently published paper (Abe et al. 2025, "Multi-wavelength study of OT 081: broadband modelling of a transitional blazar"), show a challenging theoretical interpretation because of the high Compton Dominance of the MWL SED. In the flaring episode presented in Abe et al. 2025 moreover, the source, previously categorized as a BL Lac in several occasions, presents clearly characteristics of Flat Spectrum Radio Quasars. In this contribution we report the efforts in connecting the broadband model to the VLBI data, with two zone models that we also apply to a sample of candidate transitional blazars. The goal is to deepen our knowledge of blazars of controversial categorization.
