Description

Modeling the emission of gamma-ray photons of blazars is often performed as a core step in short-term IACT blazar analyses. It is, however, of interest to analyze the temporal component of blazar emission on a long-term scale, which yields insights into temporal aspects of acceleration mechanisms through comparison with theoretical modeling.

This requires, on one hand, a consistent and reliable method for analyzing large amounts of data with reproducible configuration in a shorter timeframe. For this purpose, the database-driven automation tool autoMAGIC was developed for data from the MAGIC telescopes.

On the other hand, a theoretical modeling tool is required to provide theoretical temporal simulations for comparison with long-term lightcurve data. Hence, this use case is being developed based on the cosmic-ray propagation framework, CRPropa.

This talk presents the autoMAGIC structure and an example analysis performed with autoMAGIC, demonstrating reliability compared to established methods as well as the outline and possible challenges in the comparison with theoretical modeling.
