The conference will encompass talks presenting the most up-to-date results from recently completed and ongoing large-scale surveys spanning the entire gamut of observed wavelengths, ranging from radio, microwave, and optical to X-ray. Within this landscape of observables, the majority of the program will focus on innovative methods to combine multiple probes in order to advance our understanding of astrophysics and cosmology. Specific topics will include: Cosmic Microwave Background-Large Scale Structure (CMB-LSS) cross-correlation studies of the Sunyaev Zel’dovich effect and lensing, combined-probe analysis of galaxy clustering and lensing, measurement of the Integrated Sachs-Wolfe effect, cross-correlations of intensity mapping with other tracers of LSS, and an exploration of synergies between gravitational wave astronomy and LSS probes. The conference will provide attendees with a synoptic overview of ongoing surveys and state-of-the-art analysis techniques.
