Multimessenger insights into the ultra-high-energy universe

The origins of the most energetic particles in the Universe have been a long-standing puzzle. In the quest to identify their sources, it is crucial to understand how these particles are accelerated, how they can escape their production sites, and which roads they can take on their journey to Earth. The multimessenger framework has proven to be a powerful tool for exploring the Universe at these extreme energies.
In this talk I will focus on the triad of (ultra-)high-energy messengers: cosmic rays, neutrinos, and gamma rays. I will begin with a summary of the state of affairs in this field, reviewing some key theoretical developments and recent experimental results. I will then delve into the essential components required for building theoretical models that explain these measurements. Particular emphasis will be placed on modelling the propagation of these messengers, including their interactions with matter and radiation fields, as well as with the poorly understood cosmic magnetic fields. Finally, I will discuss the prospects of building a unified and self-consistent model of the Universe at ultra-high energies and some of the implications such a model would have for astrophysics, cosmology, and fundamental physics.
