Physics Colloquium with Ferah Munshi on Dark Matter

Ferah Munshi (Hosted by Krawczynski) from University of Oklahoma will be presenting the colloquium "Can we constrain dark matter at the limits of galaxy formation?"

Dwarf galaxies provide a very important and intriguing laboratory for the study of dark matter physics. I will present results from extremely high resolution, fully cosmological simulations that contain many isolated dwarf galaxies [the MARVELous dwarfs] as well as satellite dwarf galaxies [the DC Justice League]. Together, they create the largest collection (211) of high-resolution simulated dwarf galaxies to date and the first collection to resolve ultra-faint dwarf galaxies in multiple environments. With this flagship suite I can statistically characterize dwarf galaxies in order to constrain dark matter physics. I will present results answering the following key question: What testable predictions can we make to constrain dark matter at the lowest dwarf masses? Finally, such exquisite, high resolution simulations produce a vast amount of data - this talk will also highlight novel simulation analysis tools that leverage databases and machine learning as well as the potential for data-driven interdisciplinary collaboration.
