Oral Presentation
The microphysics of galaxy formation and evolution: the role of cosmic rays
Presenter: Ellis Owen (NTHU)
High redshift star-forming galaxies are complex multi-phase systems where hot interstellar gas, cold dense molecular clouds and energetic particles (i.e. cosmic rays) all intermingle. Stellar remnants can supply seed particles and generate the shocks needed to accelerate them to very high energies. This talk considers the interplay and interactions between the ambient partially ionised gases, dense clouds, and the energetic non-photonic cosmic ray particles in these environments. I will present the energy deposition rates by cosmic rays as they propagate within their host galaxy and beyond, and will discuss the astrophysical implications on the host galaxy.
