Title: Tracing the structure of dark matter haloes using globular clusters: insights from the E-MOSAICS simulations
Abstract: Massive galaxies predominantly grow by accreting smaller satellite galaxies. During this hierarchical build-up, stars and stellar clusters are deposited in the outskirts of the massive galaxy, where most of the dark matter lies. Diffuse stellar light and globular cluster populations are thus relics of the formation and assembly history of their host cluster. In this talk, I will discuss how we can constrain the shape, orientation and radial profile of dark matter haloes using the spatial distributions of stellar light and globular cluster populations. I will test the method using simulated star cluster populations and their host dark matter haloes from the (34.4cMpc)3 periodic volume from the E-MOSAICS project, and I will review how these numerical predictions can be tested using data from the Hubble and James Webb Space Telescopes, as well as from future data from the Euclid, Roman and Vera Rubin observatories.
