Astrophysics Colloquium: More Accurate Together: Opportunities in Multi-Survey Cosmology

The next decade will be a phase transition for observational cosmology, with upcoming imaging/spectroscopic/cosmic microwave/radio surveys mapping the sky at unprecedented precision. In this talk I will describe observational and astrophysical challenges for unlocking the cosmological information in each of these data sets individually. I will further detail how comprehensive multi-probe approaches can elevate next decade’s cosmological analyses to a new level of constraining power and robustness.
