Cosmic rays: physics, chemistry, and computational challenges
Book chapter, 2023
In regions shielded from ultraviolet radiation, energetic charged particles, called cosmic rays, are the dominant drivers of ionization, dissociation, and excitation. This chapter discusses the basics of cosmic-ray transport and acceleration, their impact on the thermochemistry of molecular gas, and methods to include cosmic-ray processes into astrochemical models.
