Dragon School: cosmic-ray theory, phenomenology and beyond

This school is intended to provide an overview about a variety of topic centered around the problem of cosmic-ray transport in the Galaxy and non-thermal diffuse emissions. We will provide both dedicated seminars and hands-on sessions on the modeling and computation of cosmic-ray propagation and the correlated non-thermal emissions in different astrophysical environments. In particular, the event will feature a detailed presentation of the state-of-the-art theoretical and numerical tools to calculate relevant astro-particle quantities (production of gamma-ray, radio or neutrino emission, as well as the signals produced by dark matter), especially focused on the broad applicability of the DRAGON2 code.

This event will be held at the Institute of Theoretical Physics in Madrid (Spain) from October 8th to October 10th 2025. The organizing committee of the workshop will be composed by the current main developers of the code: Daniele Gaggero (researcher at INFN Pisa), Silvio Sergio Cerri (researcher at Lagrange Laboratory – Observatoire Côte d’Azur, in Nice) and Pedro De la Torre Luque (Juan de la Cierva postdoc at UAM and IFT), along with Miguel Ángel Sánchez-Conde (associate professor at UAM and IFT).

The school will have a duration of three days, in which the first two days will be dedicated to lectures (during the morning), covering cosmic-ray related physics  (astrophysical plasmas, particle interactions, computational techniques, etc) and discussing the status of current observations of Galactic diffuse emissions (radio, X-ray, neutrino and gamma-ray diffuse backgrounds) and hands-on sessions (during he afternoon), while the third day will be dedicated to a number of invited talks about the use of diffuse emissions for indirect dark matter searches and the DRAGON2 code beyond the study of cosmic-ray propagation.

Title: «Propagation of cosmic rays and production non-thermal radiations with DRAGON and Hermes»

Abstract: Cosmic-ray measurements have reached unprecented precision in the last decade. These observations are  challenging our standard intepretation of how cosmic rays generated and how they propagate in the Galaxy. Therefore, it is crucial to achieve accurate predictions to understand the origin of discrepancies with data. On top of this, these predictions allow us to infer the non-thermal radiations that cosmic rays produce when they interact with Galactic magnetic fields, radiation fields and gas. This session is dedicated to provide a detailed overview of the DRAGON and Hermes codes and how they can be used to obtain predictions of the cosmic ray, gamma-ray, neutrino and even radio diffuse Galactic fluxes that are correlated.

Titulo: Diffuse radio emission

Abstract: Synchrotron emission from cosmic-ray electrons is a powerful tool for probing both the Galactic magnetic field and the energy spectrum of electrons within our Galaxy. This lecture will cover the fundamental principles of synchrotron radiation, methods for measuring this emission, and the current state of observations, with a focus on measurements in the GHz frequency range.
