Generating Synthetic Observations from Simulations of Galactic Outflows for LEM

Simulations of galactic outflows, and the outflow’s interaction with the circumgalactic medium (CGM), provide useful insights into astrophysical phenomena that cannot be resolved with current telescopes. Taking advantage of modeling tools developed in the past few years, such as pyXSIM and SOXS, we demonstrate the analytic potential of synthetic observations generated from high resolution hydrodynamical simulations of galactic outflows. In particular we focus on generating synthetic observations for the Line Emission Mapper (LEM) mission. Using simulations of a few kpc in size of starburst, AGN, and combined starburst-AGN driven outflows we demonstrate the diagnostic capabilities of these synthetic observations in recovering gas kinematics, temperature, and other gas properties. Our results provide methods of drawing direct comparisons between high resolution hydrodynamical simulations and LEM observations.
