A new method for the precise calibration of telescopes at the Cherenkov Telescope Array Observatory

A study initiated as a Physics degree thesis at the UAB has led to the first complete analytical description of muon-based calibration of the double-mirror telescopes used in gamma-ray astronomy. The new formalism allows for the precise prediction of the amount of Cherenkov light reaching the camera, taking into account the complex geometry of these instruments. The results, published in The Astrophysical Journal Supplement Series, are directly applicable to the calibration of future telescopes at the Cherenkov Telescope Array Observatory (CTAO).
