UofT AstroTour: Cosmology with galaxy clusters (ONLINE)
Speaker: Ajay Gill
Galaxy clusters form the largest gravitationally bound objects in the Universe. The growth and evolution of galaxy clusters over time is sensitive to the nature of dark matter and dark energy, two of the most profound mysteries in modern science. In this talk, Ajay Gill will describe two experiments that observe galaxy clusters: the Atacama Cosmology Telescope located at the Cerro Toco in the Atacama Desert in the north of Chile and the Superpressure Balloon-Borne Imaging Telescope (SuperBIT). In particular, he will describe how different physical mechanisms in and around galaxy clusters can allow astronomers to learn more about their properties using multi-wavelength observations of both radiation from the early as well as the late Universe.
