8. Gravitational Lensing


    In the past two decades we have witnessed tremendous progress in the field of gravitational lensing, in both the weak and strong regimes. Cosmic shear has emerged as a prime cosmological probe, strong lenses have provided unique insight on the distribution of dark matter on galaxy and cluster scales, and time-delay measurements have enabled the measurement of the late-time expansion rate of the Universe. Yet, the field is about to be revolutionized by the advent of new surveys and facilities. Stage IV cosmology experiments will provide weak lensing data of unprecedented quantity and quality, while new photometric and spectroscopic surveys will increase the number of known strong lenses by orders of magnitude. It will be possible to study new classes of lensed sources. This wealth of data will also enable the study of new classes of lensed sources such as supernovae, fast radio bursts and gravitational waves, opening up new possibilities for discovery. With this mini-symposium we aim to bring together experts in all regimes of gravitational lensing, to anticipate the opportunities and challenges that this field will face in the coming years.
