| Title |
“Star-forming galaxies through cosmic time: the impacts and signatures of cosmic rays”
|
| Abstract |
At high redshifts, protogalaxies were forming their first generations of stars in intense bursts. During their active phases, these starburst galaxies would presumably be environments rich in energetic cosmic rays due to the presence of massive stars and their remnants. Stellar remnants can supply seed particles and generate the shocks (via supernova explosions and other violent events) needed to accelerate the particles to very high energies. I will outline how these energetic particles can interact with starburst galaxy environments, and discuss the impacts they may have on the evolution and star-formation histories of their hosts, how their astrophysical effects can manifest themselves on galactic, sub-galactic and super-galactic scales, and the prospect and challenges of observing their multi-wavelength signatures with the next generation of instruments.
