Prof. Camille Avestruz is an assistant professor in the department of physics at the University of Michigan with research interests that span astrophysics, cosmology, and computation. Her primary focus is to understand the evolution of clusters of galaxies. Other aspects of her work prepare for the next decade of observations, which will produce unprecedented volumes of data. Prior to the University of Michigan, she was a joint Enrico Fermi and KICP Postdoctoral Fellow at the University of Chicago, received her PhD in Physics at Yale University, and her bachelors in Physics, Mathematics, and Dance at Barnard College.
Title: Modeling Galaxy Clusters for Cosmology
Abstract: Galaxy clusters are visible across the electromagnetic spectrum. Observations of their structure, abundance, and evolution provide constraints to cosmology. We are in a golden age of statistical power for galaxy clusters, where observations will provide multiwavelength data for tens of thousands of galaxy clusters. However, our ability to maximize the use of clusters as cosmology probes is limited by how well we measure cluster masses and quantify systematic effects in galaxy cluster detection and characterization. I will discuss modeling efforts that enable us to test for systematics that arise from both astrophysical and observational effects.
