The Nancy Grace Roman Space Telescope, NASA’s next Astrophysics Flagship mission, is on track for launch in October 2026. With its large field of view Roman can cover the area of more than 400 Hubble or 100 James Webb Space Telescope images with just one snapshot. 

Together with other ground and space-based observatories such as the Vera C. Rubin Observatory, the Dark Energy Spectroscopic Instrument, the NASA SPHEREx explorer mission, the Euclid satellite, and the Simons Observatory, the community will receive a deluge of cosmological data to explore our Universe in the coming decade.

Data from these experiments will enable a variety of cosmological measurements that can be used to study the composition and evolution of the Universe, addressing questions as fundamental as: What is the nature of Dark Energy and Dark Matter? Is Einstein’s General Relativity the correct description of Gravity? What is the mass of neutrino species? How do galaxies form and evolve over time?

In close collaboration with the Roman Science Collaboration (RSC) and the Roman Project we are organizing a winter school on multi-probe cosmology. The primary goal of the school is to interface the leading experts in the field of cosmological modeling and data analysis with the next generation of researchers (80-100 graduate students and postdocs).
