Cosmology with the Nancy Grace Roman Space Telescope

View Presentations/Virtual Seminar Thursday, Jan 27th at 10AM–12PM EST
This virtual seminar, was the rescheduled splinter meeting originally planned for the AAS 239th. This seminar discusses currently planned cosmological probes as well as new ideas for cosmological probes with Roman. Talks include an overview of cosmology including weak lensing, baryon acoustic oscillations, and supernovae with Roman; and a discussion of new ideas to explore in Roman cosmology.

Nancy Grace Roman Space Telescope Town Hall

The Nancy Grace Roman Space Telescope (formerly known as WFIRST) is a NASA flagship mission planned for launch in the mid 2020s. The Roman Space Telescope will perform breakthrough science in dark energy cosmology, exoplanet microlensing, and NIR sky surveys with its Wide Field Instrument. Roman will also feature the Coronagraph Instrument (CGI), a technology demonstration that will directly image and take spectra of exoplanetary systems using several novel technologies together for the first time in space. This session covers the status of the project and upcoming opportunities for community involvement in planning and executing the science and technology demonstration aspects of Roman.
    • Focus on Roman opportunities: ROSES call, Astrophysics Survey RFI etc.

Testing Hierarchical Models of Galaxy Evolution with the Roman Space Telescope

Through a wide variety of community defined surveys, the Roman Space Telescope will greatly expand our sampling of the structures, colors and spectroscopic properties of galaxies over a significant fraction of cosmic time. These datasets will enable the discovery of rare objects and allow us to track the growth of normal galaxies as a function of environment, advancing our understanding of galaxy evolution, and providing a solid foundation against which to test and develop models that link star formation and black hole growth to galactic dark matter halos and large scale structure. This session brings together observers and theorists to discuss how to optimize both the observing strategy and the simulation strategy to make the most incisive tests of theoretical models.
