Generating the TeV gamma-ray sky from population synthesis of pulsar environments

Year: 2025

Type: conference-paper

Abstract: Pulsar associations constitute the most numerous class of Galactic TeV sources, with pulsar wind nebulae (PWNe) and pulsar halos playing a crucial role in high-energy astrophysics. We build a population synthesis pipeline based on the COMPAS code to model stellar evolution and pulsar populations. Our framework tracks the evolution of pulsars through various PWN and pulsar halo stages, predicting both gamma-ray emission and nebular size distributions. By normalizing our model against observed northern sky surveys, we assess detectability constraints and provide a predictive outlook for the southern sky. This analysis offers valuable insights into the expected TeV source population and their observational prospects with upcoming facilities.
