  Prompt photons are created in the early stages of heavy ion collisions and
traverse the QGP medium without any interaction. Therefore, photon-triggered
jets can be used to study the jet quenching in the QGP medium. In this work,
photon-triggered jets are studied through different jet and jet substructure
observables for different collision systems and energies using the JETSCAPE
framework. Since the multistage evolution used in the JETSCAPE framework is
adequate to describe a wide range of experimental observables simultaneously
using the same parameter tune, we use the same parameters tuned for jet and
leading hadron studies. The same isolation criteria used in the experimental
analysis are used to identify prompt photons for better comparison. For the
first time, high-accuracy JETSCAPE results are compared with multi-energy LHC
and RHIC measurements to better understand the deviations observed in prior
studies. This study highlights the importance of multistage evolution for the
simultaneous description of experimental observables through different
collision systems and energies using a single parameter tune.
