Dr. Doris Stoppacher is a postdoctoral fellow in the Computational Astrophysics Research Group at the University of California, Santa Cruz. She has a background in stellar and extra-galactic astrophysics but focused on galaxy formation modeling during her PhD. She is particularly interested in the formation and evolutionary channels of today's most luminous and massive galaxies residing in halos that serve as the building blocks of the cosmic web. Her postdoctoral research centers on developing a galaxy-scale star formation and feedback model to connect early galaxy formation during the epoch of reionization with the paradigms of late-time galaxy evolution.
Talk Title and Abstract:
A semi-analytical perspective on the challenges of modern galaxy formation modelling
Galaxy evolution theory aims to explain simultaneously and self-consistently the interplay of physical processes that govern galaxy formation on large and small scales. Galaxy formation comprises one of the most challenging topics in modern astrophysics because the mechanisms driving galaxy evolution work on highly diverse spatial and temporal scales. The properties of the dark matter halos are tightly correlated to both, large scale structure formation and the evolutionary state of the galaxies which reside in them. Models of galaxy formation and cosmological simulations are useful tools helping in improving our understanding of the physical processes at work. However, the intermediate regime of modeling baryonic physics which can guarantee for both optimal resolution and good statistics is not yet sufficiently developed. My research applies innovative ideas of how to treat baryonic processes related to galaxy formation in simulations contributing to this intermediate layer. Thereby I focus on the formation channels of the progenitor of the most massive galaxies to gain a better understanding of both, galaxy evolution and the formation of large-scale structures.
