Implication

Simulation study reveals imaging constraints for resolving magnetosheath plasma jets in soft X-rays, indicating that instruments larger than SMILE-SXI are required.

Key Points

To determine the telescope aperture and observational conditions required to resolve magnetosheath plasma jets using soft X-ray emission imaging.
Simulated magnetosheath jets using hybrid-based models and generated realistic soft X-ray count maps calibrated to the SMILE Soft X-ray Imager (SXI) specifications.
Developed a Poisson means-based statistical test to quantify the contrast and photon counts necessary to distinguish single jets from foreground and astrophysical background emissions.
Line-of-sight integration significantly obscures jet structures when multiple jets overlap along the viewing path.
Resolving an isolated jet requires high density contrast, a minimum photon count threshold, strong solar wind driving to outshine background emissions, and a telescope larger than SMILE-SXI.
