Sasli Proposal Approved for part of first cycle of observations at Roman Space Telescope

Argyro Sasli, Postdoctoral Researcher in the School of Physics and Astronomy, has received word that her proposal has been accepted for the first ever cycle of observations at the Nancy Grace Roman Space telescope. The proposal will study Trans-Neptunian objects (TNOs), the most pristinely preserved remnants of the early solar system, encoding information about the formation of the outer planets. The proposal seeks to address two fundamental questions that remain poorly constrained: the TNO size-frequency distribution, and TNO surface compositions, particularly H2O ice abundance as a function of size and dynamical class. Sasli together with co-Is Bryce Bolin (Eureka Scientific), and Professor Michael Coughlin plan to use Roman's High-Latitude Wide Area Survey (HLWAS) data to simultaneously address both questions.
