"Galaxy Evolution: Gas phases and Feedback"
Studying galaxy evolution is a human endeavour. Simulations would ideally include physical models
based on relevance, but we are often limited by practical considerations like CPU time and code complexity.
I will examine energy inputs to galaxies from radiation and stellar feedback, how they are modelled in simulations,
and where they are expected to influence the state of the gas and the overall evolution of a galaxy.
I will focus on superbubbles (clustered supernova and stellar wind feedback) and local radiation fields, looking at
the differences in what these feedbacks can do in terms of where they act in the galaxy,
how that impact changes over cosmic time and how the limitations of simulations have affected our view of them.
